Changes in nail colour, texture, thickness, shape, or attachment can develop for many reasons, including injury, repeated product exposure, aging, skin conditions, infection, or underlying health concerns. Some changes are temporary and harmless, while others require assessment by a qualified healthcare professional.
This guide explains common nail plate conditions, the signs associated with them, and when professional support may be appropriate. It is intended for general education and does not replace medical diagnosis. Unexplained changes, pain, swelling, redness, warmth, or suspected infection should be assessed by a doctor, dermatologist, or podiatrist.
Paranychia
Paronychia
Paronychia is inflammation or infection of the skin surrounding the nail. Common signs include redness, swelling, tenderness, warmth, and sometimes pus. It can develop after damage to the protective skin around the nail from hangnails, biting, picking, or aggressive cuticle work.
When to Seek Medical Care
Nail services should not be performed when an active infection is suspected. A doctor or dermatologist should assess the area, particularly if symptoms are worsening, pus is present, redness is spreading, or the person has diabetes or a weakened immune system.
Onycholysis
Onycholysis is the separation of the nail plate from the nail bed. It may be associated with repeated trauma, product irritation, infection, certain medications, psoriasis, or other health conditions. The separated portion will not reattach; improvement occurs as healthy new nail grows.
Professional Guidance
The underlying cause should be identified before treatment or cosmetic enhancement is considered. Applying BIAB, gel, or acrylic over significant separation may trap moisture or place additional stress on the affected nail. Unexplained, persistent, painful, or discoloured nail separation should be assessed by a doctor or dermatologist.
Beau's Lines
Beau's lines are horizontal grooves indicating past trauma or medical issues like malnutrition. Research shows that these lines can appear after significant stressors to the body, such as surgery or severe illness.
What to Know:
Beau’s lines usually grow outward with the nail. If several nails are affected or the cause is unknown, consult a doctor or dermatologist to identify whether an illness, medication, injury, or another factor interrupted nail growth.
Yellow Nail Syndrome
Yellow nail syndrome is a rare condition characterized by yellowing nails, often accompanied by swelling and respiratory difficulties. This syndrome may occur alongside chronic respiratory conditions.
What to Know:
Yellow, thickened, or slow-growing nails can have several possible causes. Unexplained changes particularly when accompanied by swelling or respiratory symptoms should be assessed by a doctor.
Koilonychia
Koilonychia, colloquially known as spoon nails, features nails that curve upward. This condition can sometimes be associated with iron-deficiency anemia or another underlying health concern.
What to Know:
If you suspect koilonychia, it’s important to consult a healthcare professional for a proper diagnosis. Keeping your nails moisturized also aids in maintaining nail health.
Nail Fungal Infections
Nail fungal infections can result in discoloration, thickening, and brittleness. Fungi thrive in damp environments, and wearing wet shoes can increase your risk significantly.
What to Know:
Keeping nails clean and dry is vital to preventing future infections.
Onychogryphosis
Onychogryphosis manifests as thick, claw-like nails, often affecting toenails. It can result from neglect, trauma, or systemic conditions. Proper care is essential, especially for people with diabetes, where this condition is more prevalent.
What to Know:
Regular trimming and filing can help manage this condition. Consult with a healthcare provider for underlying issues, and adopt proper foot hygiene practices to prevent worsening.
Nail Clubbing
Nail clubbing occurs when nails curve downward, which may indicate respiratory or cardiovascular diseases.
What to Know:
It is crucial to consult a doctor if you notice nail clubbing.
Ingrown Toenail
Ingrown Toenail
An ingrown toenail develops when the edge or corner of the nail presses into the surrounding skin. It most commonly affects the big toe and may cause tenderness, redness, swelling, or inflammation. Contributing factors can include improper trimming, tight footwear, repeated pressure, injury, or the natural shape of the nail.
When to Seek Professional Care
A doctor or podiatrist should assess an ingrown toenail if it is painful, swollen, recurring, or showing signs of infection such as pus or spreading redness. Clients with diabetes, poor circulation, or reduced sensation should seek medical or podiatry guidance rather than salon treatment.
Leukonychia
Leukonychia presents as white spots or lines on nails, typically due to trauma, allergies, or health concerns. It’s usually harmless but can generate cosmetic anxiety in some individuals.
What to Know:
In most cases, leukonychia needs no treatment. Maintaining good nail hygiene and keeping nails trimmed can improve their appearance. However, if you see persistent white marks with other symptoms, consult a healthcare provider.
Nail Discoloration
Changes in nail color can range from yellow to blue and may signal various health issues, including infections or lack of oxygen. In fact, blue nails can indicate respiratory problems and should be treated as a red flag.
What to Know:
Identifying the underlying cause is critical for treatment. If discoloration correlates with health issues, seek professional advice. Practicing proper nail hygiene can help maintain healthy nails.
Psoriatic Onychodystrophy
This condition is linked to psoriasis and involves nail changes like pitting, thickening, and discoloration.
What to Know:
A doctor or dermatologist should assess suspected nail psoriasis. Cosmetic nail services should only be considered when the nail and surrounding skin are stable and free from active inflammation.
Nail Thickening
Nail thickening can indicate underlying issues such as fungal infections or psoriasis. This condition often demands attention, as it can complicate nail trimming.
What to Know:
Consult a healthcare professional to diagnose the cause of thickening.
Onychoschizia
Onychoschizia refers to splitting or peeling of the nails, often attributed to dehydration or overexposure to chemicals. This condition can of people who frequently expose their hands to water.
What to Know:
Reducing repeated water exposure, wearing gloves during household cleaning, and regularly moisturizing the nails may help limit further splitting. Once medical concerns have been ruled out, IBX or another appropriate strengthening service may provide cosmetic support while the damaged nail grows.
Pincer Nail
Pincer nails curve inward, resembling a pincer. This condition can be painful and unpleasant if not managed properly.
What to Know:
Painful, severe, or worsening pincer nails should be assessed by a podiatrist or doctor. Avoid aggressive trimming or attempting to correct the nail through a standard pedicure.
Pitting
Pitting appears as small depressions on the nail surface, often linked to psoriasis. While common, pitting can affect self-esteem and confidence levels.
What to Know:
Addressing the underlying condition is crucial. Regular fingernail care can help reduce the visibility of pits.
Nail Psoriasis
Nail psoriasis leads to various changes, including discolouration, pitting, and separation from the nail bed. It’s often an indicator of an autoimmune condition.
What to Know:
Suspected nail psoriasis should be assessed by a doctor or dermatologist. Avoid covering actively inflamed, painful, separating, or significantly damaged nails with cosmetic enhancements.
Splinter Hemorrhage
Splinter hemorrhages appear as small red or brown lines under the nails. They may result from trauma or indicate significant conditions like endocarditis.
What to Know:
If you notice splinter hemorrhages, seeing a healthcare provider is essential to rule out serious conditions. Minor cases due to trauma may not need treatment.
Blue Fingernails
Blue fingernails signal possible oxygen deprivation in the blood, which may arise from respiratory issues or circulatory problems. Immediate medical attention could be critical.
What to Know:
New or unexplained blue nail colour should be medically assessed, particularly if it is accompanied by breathing difficulty, chest discomfort, dizziness, or blue colour around the lips.
Crumbling Nails
Crumbling nails feel brittle and break easily. They may result from frequent hand washing, chemical exposure, or fungal infections.
What to Know:
Keep your nails moisturized, and adopt a gentle nail care routine. Use protective gloves for household chores to reduce crumbling.
Median Canaliform Nail Dystrophy
Median canaliform nail dystrophy causes a central ridge in the nail, leading to abnormal growth. It may resolve spontaneously, or be secondary to other nail issues.
What to Know:
This condition usually doesn't require treatment unless it becomes bothersome. Regular trimming and moisturizing keep the nails healthy.
Ridges
Ridges can be vertical or horizontal, often associated with aging. While generally harmless, they can sometimes indicate nutritional deficiencies.
What to Know:
Vertical ridges commonly become more noticeable with age. Deep horizontal grooves, sudden changes, or ridges affecting several nails should be medically assessed when the cause is unknown.
Terry's Nails
Terry’s nails feature a white discoloration with a dark band at the tip, often reflecting liver or kidney diseases. Early identification can be critical for underlying health issues.
What to Know:
Consulting a healthcare provider is essential to determine the root cause. Treating the underlying health issue often improves nail appearance.
Severely Damaged Nail
A destroyed nail may result from trauma or infections and can be painful. Immediate hygiene and care are critical.
What to Know:
Clean the area thoroughly and protect it with a bandage. If there's significant pain or signs of infection, seek medical attention promptly.
When to Book a Nail Assessment
A professional nail assessment may be helpful if you are experiencing:
Persistent peeling, splitting, or brittleness without signs of infection
Nail weakness following improper product removal
Difficulty choosing between IBX, BIAB, hard gel, or another nail service
Repeated breakage during natural nail growth
Concerns about whether your nails are suitable for a cosmetic enhancement
The assessment helps identify appropriate cosmetic care and whether a medical referral is advisable. Pain, swelling, warmth, pus, unexplained discolouration, or suspected infection should be assessed by a qualified healthcare professional.
Supporting Your Natural Nail Health
Not every nail change is suitable for cosmetic treatment. Pain, swelling, warmth, unexplained discoloration, nail separation, or suspected infection should be assessed by a qualified healthcare professional before a salon service is performed.
Once medical concerns have been ruled out, professional nail care may help protect weak or damaged natural nails. Depending on the condition and your goals, appropriate options may include:
IBX treatment for peeling, splitting, or weakened natural nails
BIAB structured manicures for added support and protection
Gentle dry manicure techniques that minimize soaking and unnecessary trauma
A personalized maintenance plan based on nail condition and lifestyle
Unsure Which Nail Service Is Right for You?
A Nail Health Assessment provides a one-on-one evaluation of your natural nails and helps determine whether IBX, BIAB, hard gel, or another approach is most appropriate.
