Decoding Your Toenail Health: A Comprehensive Guide

Our toenails, often relegated to an afterthought in our daily grooming routines, are far more than just protective coverings for our toes. They are intricate barometers of our overall health, capable of revealing subtle clues about nutrient deficiencies, underlying medical conditions, and even the presence of systemic diseases. Learning to “read” your toenails is a powerful skill, empowering you to identify potential issues early and seek timely medical advice. This definitive guide will equip you with the knowledge to decode the silent language of your toenails, transforming you into an astute observer of your own well-being.

The Anatomy of a Healthy Toenail: What to Look For

Before we delve into the myriad ways toenails can signal health issues, it’s crucial to understand what a healthy toenail should look like. This provides a baseline against which to compare any abnormalities you might observe.

A healthy toenail typically exhibits the following characteristics:

• Color: Evenly pinkish, indicating good blood flow beneath the nail plate. The lunula (the half-moon shape at the base of the nail) should be visible, a slightly lighter, opaque white.

• Surface: Smooth and uniform, free from ridges, pits, or grooves. There should be no signs of flaking, splitting, or peeling.

• Thickness: Moderately thick and consistent across the nail plate. It should not be excessively thick or unusually thin.

• Shape: Gently curved, mirroring the contour of your toe. It should not be dramatically curled inward (ingrown) or excessively flattened.

• Texture: Firm but flexible, not brittle or overly soft.

• Cuticle: Intact, healthy, and attached to the nail plate, acting as a protective barrier against bacteria and fungi.

• Growth: Steady and continuous. While toenails grow slower than fingernails, a noticeable lack of growth can be a red flag.

Think of your healthy toenail as a perfectly manicured miniature landscape – smooth, consistent, and vibrant. Any deviation from this ideal warrants closer inspection.

Color Clues: What Your Toenail Hue Reveals

The color of your toenails offers some of the most immediate and telling insights into your internal health. Subtle shifts in hue can indicate a range of conditions, from benign cosmetic issues to serious systemic diseases.

Yellowing Toenails: More Than Just Stains

Yellow toenails are one of the most common complaints, and while often attributed to aging or nail polish, they can signify deeper problems.

• Fungal Infection (Onychomycosis): This is by far the most frequent cause of yellowing. The nail may also become thick, brittle, and develop a foul odor. The yellowing often starts at the tip or side of the nail and spreads. Example: Imagine a runner who frequently wears sweaty shoes develops a yellowish, crumbling big toenail. This is a classic presentation of toenail fungus.

• Psoriasis: Psoriasis can affect nails, causing them to yellow, thicken, and develop pits. This is often accompanied by skin involvement elsewhere on the body. Example: A person with a history of psoriatic skin plaques notices their toenails turning a cloudy yellow with small indentations.

• Lymphedema: In rare cases, yellow nail syndrome (a triad of yellow nails, lymphedema, and respiratory problems) can occur. Here, the nails are typically very thick and slow-growing. Example: An individual experiencing swelling in their legs also notices their toenails have become uniformly thick, hard, and yellow.

• Diabetes: Poor circulation and increased susceptibility to infections in diabetic individuals can lead to yellowed, thickened nails. Example: An elderly individual with poorly controlled diabetes observes their toenails developing a persistent yellowish tint and becoming more difficult to trim.

• Aging: As we age, toenails naturally thicken and can take on a yellowish hue due to slower growth and increased exposure to environmental factors. This is generally uniform and not accompanied by other symptoms. Example: A healthy 80-year-old notices their toenails are a light yellow, but otherwise appear normal and healthy.

• Smoking: Nicotine and tar can stain nails, leading to a yellow or brownish discoloration, particularly on the nails of the toes closest to the cigarette during smoking. Example: A long-term smoker observes their big toenails have a faint yellow-brown stain on the tips, consistent with years of nicotine exposure.

White Patches or Spots: A Spectrum of Significance

White marks on toenails, known as leukonychia, can range from harmless to indicative of underlying health issues.

• Trauma: The most common cause of white spots or lines is minor injury to the nail matrix (the area where the nail grows from). These marks grow out with the nail. Example: You accidentally drop a heavy object on your toe, and a few weeks later, a white spot appears, slowly moving up the nail as it grows.

• Fungal Infection (Superficial White Onychomycosis): This type of fungal infection presents as powdery white spots on the surface of the nail that can be scraped off. Example: A person notices a chalky white patch on the surface of their toenail that seems to spread and can be easily scraped with a nail file.

• Nutritional Deficiencies: While often cited, zinc or calcium deficiencies are rarely the sole cause of white spots. However, severe malnutrition can impact nail health. Example: In extreme cases of prolonged dietary deprivation, a person might exhibit widespread white streaking on multiple nails.

• Systemic Illnesses (Rare): In very rare instances, white nails can be a sign of more serious conditions like liver disease (Terry’s nails, where most of the nail is white with a narrow pink band at the tip) or kidney disease. Example: A patient with advanced liver cirrhosis presents with nails that are predominantly white, except for a thin, dark band near the fingertip.

• Allergic Reaction: An allergic reaction to nail polish, hardeners, or adhesives can sometimes manifest as white patches or streaks. Example: After using a new type of nail polish, an individual develops several small, irregular white spots on their toenails.

Blue or Purplish Toenails: Circulatory Alarms

A bluish or purplish tint to toenails often points to issues with oxygenation or blood circulation.

• Subungual Hematoma (Bruise): This is the most common cause, resulting from trauma that causes bleeding under the nail. The color will typically be dark blue, purple, or even black, and will grow out with the nail. Example: You stub your toe forcefully, and within hours, your toenail turns a deep purplish-black due to blood pooling underneath.

• Poor Circulation/Cyanosis: Lack of oxygen in the blood can cause the nail bed to appear bluish. This can be due to cold exposure, Raynaud’s phenomenon, or more serious conditions like heart or lung disease. Example: In extremely cold weather, a person’s toenails might temporarily take on a bluish hue as their body constricts blood vessels to conserve heat.

• Silver Poisoning (Argyria – Rare): Prolonged exposure to silver can lead to a grayish-blue discoloration of the skin and nails. Example: A person who has been taking colloidal silver supplements for an extended period notices a subtle bluish tint developing on their nails.

• Certain Medications: Some medications, particularly certain antimalarial drugs, can cause blue discoloration of the nails. Example: A patient undergoing treatment with a specific antimalarial drug observes that their toenails have acquired a faint but noticeable bluish tinge.

Black or Brown Toenails: From Bruises to Moles

Dark discoloration beneath the toenail is always a cause for closer examination, as it can range from a simple bruise to something far more serious.

• Subungual Hematoma (Bruise): As mentioned with blue nails, trauma can cause blood to collect under the nail, appearing black or very dark brown. This is the most common reason. Example: An avid hiker develops a black big toenail after a long downhill trek, indicating repetitive micro-trauma from their shoes.

• Melanonychia Striata: This appears as a vertical brown or black streak on the nail. It’s caused by melanin production in the nail matrix. In individuals with darker skin tones, this is often benign and common. However, it can also be a sign of:

  • Benign Nevus (Mole): A harmless mole in the nail matrix.

  • Melanoma: A serious form of skin cancer. Any new, rapidly changing, wide, or irregularly pigmented dark streak warrants immediate medical evaluation. Example: A fair-skinned individual notices a new, wide, and irregularly shaped black streak appearing on their toenail that rapidly grows wider over a few months. This requires urgent medical attention.

  • Racial Melanonychia: Common and benign in individuals with darker skin, presenting as uniform, narrow, longitudinal streaks. Example: A person of African descent has had a thin, consistent brown line on their thumbnail for years, which is a normal variation.

• Fungal Infection: While less common, some fungal infections can cause dark brown or black discoloration, often accompanied by thickening and crumbling. Example: A person with a long-standing fungal infection notices one of their toenails has turned a dark, muddy brown, along with the usual thickening.

• Medications: Certain medications, like some chemotherapy drugs, can cause nail discoloration, including darkening. Example: A patient undergoing chemotherapy observes their toenails becoming significantly darker during their treatment cycle.

Red Streaks or Spots: Bleeding Under the Surface

Red marks on the toenails usually signify bleeding or inflammation.

• Splinter Hemorrhages: These appear as tiny, thin red or reddish-brown lines resembling splinters under the nail. They are caused by damaged capillaries. While often due to minor trauma, they can also indicate:
  • Endocarditis: An infection of the heart’s inner lining. Example: A person with a heart murmur develops unexplained fever and new splinter hemorrhages under several nails, prompting an urgent cardiac workup.

  • Psoriasis: Can cause splinter hemorrhages.

  • Trauma: The most common cause, especially in active individuals. Example: A construction worker frequently dropping tools on their feet might notice occasional splinter hemorrhages due to repetitive minor trauma.

• Subungual Hematoma: As discussed, a large bruise can appear deep red before turning purple or black. Example: Immediately after a severe stubbed toe, the area under the nail might appear bright red before turning darker as the blood clots.

Surface and Texture Abnormalities: Beyond the Smooth

Beyond color, the surface and texture of your toenails offer a wealth of information. Any deviation from a smooth, uniform appearance can be a health indicator.

Ridges and Grooves: Lines of Insight

• Vertical Ridges (Longitudinal): These are very common and usually harmless, often becoming more prominent with age. They reflect the natural aging process of the nail matrix. Example: An elderly individual has faint, parallel lines running the length of their toenails, which have been present for years and cause no concern.

• Horizontal Grooves (Beau’s Lines): These are depressions that run across the nail. They indicate a temporary interruption of nail growth, often due to:

  • Severe Illness: High fever, infection, or major surgery. Example: After a prolonged hospitalization due to a severe respiratory infection, a person notices distinct horizontal grooves appearing on their nails, growing out from the base.

  • Nutritional Deficiency: Especially protein deficiency.

  • Medications: Certain drugs can cause them.

  • Extreme Stress: Physical or emotional.

  • Trauma to the Nail Matrix: Repetitive pressure from ill-fitting shoes. Example: A runner develops horizontal lines on their big toenails, consistent with the pressure exerted by tight running shoes during long distances.

Pitting and Crumbling: Signs of Underlying Disease

• Pitting: Small, pinpoint depressions on the nail surface. This is a classic sign of:

  • Psoriasis: Often accompanied by oil spots (yellow-red discoloration under the nail) and onycholysis (nail separation). Example: A person with diagnosed psoriasis notices their toenails developing numerous tiny, irregular depressions, almost like they’ve been pricked with a pin.

  • Alopecia Areata: An autoimmune condition causing hair loss. Example: An individual experiencing patchy hair loss also observes small pits forming on their toenails.

  • Eczema: Severe eczema affecting the digits can sometimes lead to nail pitting.

• Crumbling or Brittleness: Nails that easily break, flake, or crumble are usually a sign of:

  • Fungal Infection (Onychomycosis): As the infection progresses, the nail becomes increasingly brittle and easily breaks apart. Example: A person’s once-firm toenail now seems to shatter and crumble with minimal pressure, indicating advanced fungal infection.

  • Thyroid Disorders: Both hypo- and hyperthyroidism can affect nail health, leading to brittleness and dryness. Example: An individual diagnosed with an underactive thyroid notices their toenails becoming exceptionally dry and prone to breaking easily.

  • Nutritional Deficiencies: Lack of biotin, iron, or protein can contribute to brittle nails. Example: Someone following a restrictive diet who is also experiencing hair thinning notices their toenails are unusually brittle and prone to chipping.

  • Repeated Exposure to Water/Chemicals: While more common in fingernails, excessive exposure can also impact toenail integrity.

Thickening (Onychauxis) and Thinning: Changes in Density

• Thickening (Onychauxis): Excessively thick nails can be challenging to trim and often indicate:

  • Fungal Infection: The most common cause, often accompanied by discoloration and brittleness. Example: A person’s big toenail has grown progressively thicker over years, making it difficult to cut, along with a yellowish hue.

  • Aging: As mentioned, nails naturally thicken with age. Example: An elderly individual has generally thicker toenails than they did in their youth, but they are otherwise healthy.

  • Trauma: Chronic, repetitive trauma (e.g., tight shoes, sports) can lead to compensatory thickening of the nail plate. Example: A soccer player develops noticeably thicker big toenails due to the constant impact and pressure within their cleats.

  • Psoriasis: Can cause significant nail thickening.

  • Peripheral Vascular Disease: Reduced blood flow can lead to thickened, discolored nails. Example: A patient with poor circulation in their feet notices their toenails have become very thick, hard, and discolored.

• Thinning: Unusually thin nails that are prone to tearing or breaking can point to:

  • Nutritional Deficiencies: Especially iron deficiency anemia (sometimes leading to “spoon nails” or koilonychia). Example: A person suffering from severe iron deficiency anemia finds their nails are unusually thin, soft, and even develop a concave, spoon-like shape.

  • Lichen Planus: An inflammatory condition affecting skin, hair, and nails.

  • Raynaud’s Phenomenon: Severe cases can impact nail health due to poor circulation.

Shape and Growth Abnormalities: Beyond the Standard Curve

The way your toenails grow and their overall shape can also provide crucial clues.

Ingrown Toenails: More Than Just a Nuisance

• Ingrown Toenails (Onychocryptosis): Occur when the nail grows into the surrounding skin, causing pain, redness, swelling, and sometimes infection.
  • Improper Trimming: Cutting nails too short or rounding the corners is a primary cause. Example: A teenager who consistently cuts their toenails too short experiences recurrent pain and redness in the corner of their big toe, leading to an ingrown nail.

  • Ill-Fitting Footwear: Shoes that are too tight or narrow compress the toes, forcing the nail into the skin. Example: A person who wears tight dress shoes daily develops a recurring ingrown toenail on their big toe.

  • Trauma: Stubbing the toe or repetitive pressure can predispose to ingrown nails.

  • Genetic Predisposition: Some people naturally have nail shapes that are more prone to ingrowing.

  • Nail Fungi: Thickened fungal nails can press into the skin.

Clubbing: A Serious Respiratory or Cardiac Sign

• Clubbing: The nails curve significantly downward, resembling the round end of a club, and the fingertips often become enlarged and bulbous. This is a serious sign of chronic oxygen deprivation and often indicates:

  • Lung Diseases: Chronic obstructive pulmonary disease (COPD), lung cancer, cystic fibrosis. Example: A long-term smoker with chronic breathing difficulties develops pronounced clubbing in their toenails and fingernails.

  • Heart Disease: Congenital heart defects, endocarditis.

  • Gastrointestinal Diseases: Crohn’s disease, ulcerative colitis.

  • Liver Disease: Cirrhosis.

  • Thyroid Disorders: In rare cases.

  • Example: A person with newly diagnosed inflammatory bowel disease notices their toenails and fingertips starting to curve downward and widen.

Spoon Nails (Koilonychia): A Sign of Iron Deficiency

• Koilonychia: The nail plate becomes thin, brittle, and develops a concave, spoon-like depression. This is a classic sign of:

  • Iron Deficiency Anemia: The most common cause. Example: A woman experiencing fatigue and pale skin also notices her nails are unusually soft and have developed a distinctive scoop-like indentation in the center.

  • Hemochromatosis: Iron overload disorder.

  • Raynaud’s Phenomenon: Severe cases can contribute.

  • Trauma: Repetitive trauma to the nail can sometimes mimic koilonychia.

  • Example: A vegan who hasn’t been diligent about iron intake exhibits spoon-shaped nails along with other symptoms of anemia.

Perionychium and Cuticle Health: The Surrounding Story

The skin and cuticle surrounding your toenail are just as important as the nail plate itself. Their condition can reveal infections or systemic issues.

Redness and Swelling (Paronychia): Infection or Inflammation

• Paronychia: Inflammation or infection of the skin around the nail.
  • Acute Paronychia: Often caused by bacterial infection (e.g., Staphylococcus) from trauma, aggressive cuticle pushing, or nail-biting. Presents with rapid onset of pain, redness, swelling, and often pus. Example: After a pedicure where the cuticles were aggressively trimmed, a person develops a painful, red, and swollen area around their big toenail, with pus forming.

  • Chronic Paronychia: Often caused by fungal infection (Candida) or repeated exposure to irritants/wet environments. Develops slowly, with tenderness, mild swelling, and cuticle retraction. Common in individuals whose hands or feet are frequently wet. Example: A cleaner who constantly has their feet in damp shoes notices chronic redness, mild swelling, and a receding cuticle around several toenails, despite no acute injury.

  • Psoriasis: Can cause inflammation and redness around the nail.

  • Allergic Contact Dermatitis: Reaction to chemicals, nail polish, or adhesives.

Absent or Damaged Cuticle: Losing a Protective Barrier

• Absent or Severely Damaged Cuticle: The cuticle acts as a vital seal, protecting the nail matrix from infection. A damaged or absent cuticle can be due to:

  • Overly Aggressive Manicures/Pedicures: Cutting or pushing back the cuticle too forcefully. Example: After a professional pedicure, a person notices their cuticles are visibly red and raw, and later develop an infection.

  • Nail Biting/Picking: Habitual manipulation of the nails.

  • Certain Skin Conditions: Eczema or psoriasis.

  • Example: A person with a habit of picking at their cuticles frequently experiences paronychia due to the compromised protective barrier.

The Role of Systemic Diseases: Toenails as Diagnostic Clues

It’s vital to remember that toenail changes are often just one piece of a larger puzzle. Many systemic diseases manifest on the nails, making them valuable diagnostic indicators.

• Diabetes:
  • Yellowing and Thickening: Due to poor circulation and increased susceptibility to fungal infections.

  • Slow Growth: Impaired circulation reduces nutrient delivery to the nail matrix.

  • Increased Risk of Ingrown Nails and Infections: Neuropathy can reduce sensation, leading to unnoticed injuries, and impaired immune function increases infection risk. Example: A diabetic patient with peripheral neuropathy doesn’t feel a small ingrown toenail developing, which then becomes severely infected.

• Thyroid Disorders (Hypothyroidism and Hyperthyroidism):

  • Brittle, Dry Nails: Both conditions can impact nail strength and hydration.

  • Slow or Rapid Nail Growth: Hypothyroidism can slow growth, while hyperthyroidism can accelerate it.

  • Onycholysis (Nail Separation): Particularly in hyperthyroidism (Plummer’s nails). Example: A person recently diagnosed with an overactive thyroid notices one of their toenails has begun to lift from the nail bed at the tip.

• Kidney Disease:

  • Half-and-Half Nails (Lindsay’s Nails): The proximal (lower) half of the nail is white, and the distal (upper) half is pink or brown. This occurs due to increased connective tissue and blood vessel changes. Example: A patient undergoing dialysis for chronic kidney failure exhibits the distinct half-white, half-pink appearance on several of their nails.

  • Terry’s Nails (also Liver Disease): Predominantly white with a narrow, dark band at the tip.

• Liver Disease:

  • Terry’s Nails: Widespread whitening of the nail, with only a narrow band of pink or brown at the tip. Associated with cirrhosis. Example: An individual with alcoholic cirrhosis shows signs of advanced liver disease, including prominent Terry’s nails.

  • Clubbing: Can be seen in chronic liver disease.

• Heart Disease:

  • Clubbing: As discussed, a significant sign of chronic oxygen deprivation.

  • Splinter Hemorrhages: Can indicate endocarditis.

  • Cyanosis (Bluish Nails): Poor oxygenation.

• Anemia (Iron Deficiency):

  • Koilonychia (Spoon Nails): The most characteristic sign.

  • Pale Nail Beds: Less visible in toenails than fingernails, but still possible.

  • Brittle Nails: Prone to breaking.

• Psoriasis:

  • Pitting: Small indentations on the nail surface.

  • Onycholysis: Separation of the nail from the nail bed.

  • Oil Spots (Salmon Patches): Yellow-reddish discoloration under the nail.

  • Thickening and Crumbly Nails: Can resemble fungal infections.

  • Splinter Hemorrhages: Small red streaks under the nail.

  • Example: A dermatologist examining a patient for psoriasis observes several classic nail changes, including pitting and areas of nail separation, confirming the diagnosis.

• Lichen Planus:

  • Thinning of the nail plate.

  • Longitudinal ridging.

  • Pterygium: The cuticle grows forward and fuses with the nail plate, causing a V-shaped defect.

  • Total Nail Loss (Anonychia): In severe cases.

Actionable Steps: What to Do When You Notice a Change

Observing a change in your toenails is the first step; knowing what to do next is crucial. Not every change requires immediate panic, but some warrant prompt medical attention.

When to Self-Monitor:

• Minor Trauma: A small bruise or white spot after an obvious injury.

• Temporary Discoloration: From nail polish, or if a minor blue tinge resolves quickly after warming up.

• Age-Related Changes: Gradual thickening or vertical ridges that are uniform and not accompanied by other symptoms.

• Isolated, Benign Changes: A single, small, unchanging white spot from a remembered minor impact.

In these cases, observe the nail. Does the discoloration grow out with the nail? Does the symptom resolve? If so, it’s likely benign.

When to See a Podiatrist or Dermatologist:

• Suspected Fungal Infection: Yellowing, thickening, crumbling, foul odor. Early treatment is key. Action: Schedule an appointment for a fungal culture and appropriate antifungal treatment.

• Painful or Infected Ingrown Toenail: Especially if red, swollen, or pus is present. Action: Avoid self-treatment that could worsen the infection. A podiatrist can safely remove the offending nail edge.

• Significant Thickening, Brittleness, or Separation: That isn’t resolving or is worsening. Action: These could be signs of fungal infection, psoriasis, or systemic issues requiring diagnosis.

• New or Changing Dark Streaks/Spots: Particularly if irregular, wide, rapidly growing, or extending into the cuticle. Action: This requires immediate evaluation to rule out melanoma. Don’t delay.

• Sudden or Unexplained Changes: Any rapid onset of discoloration, pitting, or unusual growth patterns without a clear cause. Action: Seek professional opinion to identify the underlying cause.

• Multiple Nail Involvement: If several toenails are affected, it increases the likelihood of a systemic issue rather than just a local problem. Action: Discuss the widespread changes with a healthcare professional.

When to Consult Your Primary Care Physician:

• Signs of Systemic Illness: If nail changes are accompanied by other symptoms like unexplained weight loss, fatigue, fever, shortness of breath, new pain, or swelling. Action: Your primary care doctor can conduct initial tests and refer you to a specialist (e.g., endocrinologist, rheumatologist, cardiologist) if a systemic condition is suspected.

• Suspected Nutritional Deficiencies: If you suspect issues like iron deficiency, your PCP can order blood tests. Action: Discuss your dietary habits and any other symptoms that might indicate a deficiency.

• Known Chronic Conditions: If you have diabetes, thyroid disease, kidney disease, or other chronic illnesses, report any new nail changes to your managing physician. They can assess if the changes relate to your existing condition or its management. Example: A diabetic patient reporting new nail changes to their endocrinologist could trigger adjustments in their diabetes management plan.

Prevention and Maintenance: Cultivating Healthy Toenails

Prevention is always better than cure. Adopting good toenail care habits can significantly reduce your risk of many common problems and help you maintain optimal nail health.

• Proper Trimming:
  • Cut nails straight across, not curved. This prevents ingrown toenails.

  • Do not cut them too short. Leave a small amount of white nail at the tip.

  • Use clean, sharp nail clippers specifically for toenails.

  • Example: After showering, when nails are softer, use a large, straight-edged toenail clipper to make a clean cut straight across, then gently file any sharp corners.

• Choose the Right Footwear:

  • Shoes should fit well, with ample room in the toe box. Avoid shoes that pinch your toes or are too tight.

  • Wear breathable materials to reduce moisture buildup.

  • Change socks daily, especially if they become damp.

  • Example: When buying new shoes, always try them on in the afternoon when your feet are slightly swollen, and ensure there’s a thumb’s width between your longest toe and the end of the shoe.

• Maintain Foot Hygiene:

  • Wash feet daily with soap and water.

  • Dry feet thoroughly, especially between the toes, to prevent fungal growth.

  • Moisturize your feet, but avoid applying lotion directly to the nail bed or between toes, which can trap moisture.

  • Example: After showering, use a dedicated towel for your feet, paying extra attention to drying the spaces between your toes before putting on socks.

• Protect Your Feet:

  • Wear flip-flops or shower shoes in public changing rooms, gyms, and showers to prevent fungal infections.

  • Protect your toes from trauma.

  • Example: When using a public gym shower, always slip on your rubber shower sandals to avoid direct contact with the floor.

• Diet and Hydration:

  • A balanced diet rich in vitamins (especially biotin), minerals (iron, zinc), and protein supports healthy nail growth.

  • Stay adequately hydrated.

  • Example: Incorporate foods like eggs, nuts, leafy greens, and lean proteins into your daily meals to provide essential nutrients for strong nails.

• Avoid Harsh Chemicals:

  • Limit exposure to harsh nail polish removers (opt for acetone-free).

  • Use gloves when handling strong cleaning products.

  • Example: When removing old nail polish, choose a non-acetone remover and follow up with a moisturizing cuticle oil.

• Professional Pedicures (with Caution):

  • Ensure the salon follows strict hygiene protocols (sterilized instruments, new files for each client).

  • Avoid aggressive cuticle trimming.

  • Example: Before getting a pedicure, observe the salon’s cleanliness and don’t hesitate to ask about their sterilization procedures for tools.
