Onychoschizia – Peeling/splitting layers from frequent wetting, chemicals, or iron deficiency. Trachyonychia – Rough, sandpaper-like nails seen in alopecia areata, eczema, or lichen planus. Psoriatic Pitting – Shallow pits due to abnormal keratinization in psoriasis. Alopecia Areata Pitting – Fine, regular pits from autoimmune matrix involvement. Lichen Planus (Nails) – Thinning, ridging, and possible scarring of the nail plate. Darier Disease – Red/white streaks with V-shaped notches at the nail edge. True Leukonychia – Nail plate whitening from abnormal keratin formation. Leukonychia (General) – White discoloration from nail plate/bed changes (often trauma or illness). Apparent Leukonychia – Nail bed whitening that fades with pressure (e.g., Terry’s nails). Clubbing – Rounded fingertips and curved nails; associated with lung, heart, or GI disease. Brachyonychia – Short, broad nails; congenital or linked to hyperparathyroidism. Onychogryphosis – Thick, curved “ram’s horn” nails from neglect, trauma, or vascular disease. Dorsal Pterygium – Scarring skin growth over the nail (lichen planus). Ventral Pterygium – Nail plate adhesion underneath; seen in connective tissue disorders. Splinter Hemorrhages – Thin red-brown streaks; trauma, vasculitis, or endocarditis. Pincer Nail – Excessive side-to-side curvature causing pain; arthritis or tight footwear. Yellow Nail Syndrome – Thick, slow-growing yellow nails with respiratory disease or lymphedema. Pachyonychia Congenita – Genetic thick nails with painful palm/sole calluses. Koilonychia (Spoon Nails) – Concave nails often tied to iron-deficiency anemia. Onychauxis – Thickened nails from aging, trauma, or psoriasis.

  • Inherited traits
  • Infections (bacterial, fungal, or viral)
  • Medical conditions (such as psoriasis, thyroid disorders, or fungal infections elsewhere on the body)
  • Nutritional deficiencies (iron, zinc, or biotin)
  • Exposure to chemicals (nail polish removers, detergents, or cleaning products)
  • Trauma or injury to the nail
  • Poor nail care habits (biting nails, picking at cuticles, or using nails as tools)

Diagnosing Hand Nail Conditions

Diagnosing hand nail conditions typically involves a physical examination of the nails and surrounding skin. In some cases, a sample of the nail may be taken for laboratory testing to identify any underlying infections or conditions. Your healthcare provider may also ask about your medical history, nail care habits, and any recent illnesses or injuries.

Treatment Options for Hand Nail Conditions

The treatment for hand nail conditions depends on the underlying cause. Some conditions may resolve on their own with simple nail care and lifestyle changes, while others may require medical treatment. Here are some common treatment options:

Condition Treatment
Brittle Nails Keeping nails moisturized, wearing gloves when handling water or chemicals, and avoiding nail polish removers with acetone.
Fungal Nail Infection Antifungal medication (oral or topical), nail polish with antifungal ingredients, or laser treatment.
Nail Biting Behavior therapy, habit reversal training, or wearing gloves to prevent biting.
Splitting Nails Keeping nails moisturized, avoiding nail polish removers with acetone, and filing nails into a rounded shape.
Pitting Nails Treatment of any underlying conditions, such as psoriasis or connective tissue disorders.
White Spots on Nails No treatment usually necessary, as they are often harmless. If caused by a fungal infection, antifungal medication may be prescribed.
Nail Psoriasis Topical treatments, light therapy, or systemic medications to manage psoriasis symptoms.
Nail Clubbing Treatment of any underlying lung or gastrointestinal conditions, as nail clubbing can be a sign of an underlying medical condition.

Gilbert - Fingernails can serve as small but powerful indicators of overall health. Changes in their color, texture, or growth pattern often reflect underlying nutritional deficiencies or medical conditions. For example, brittle nails may suggest a lack of vitamins or thyroid issues, while yellow nails can be linked to diabetes or fungal infections. Horizontal or vertical ridges may indicate mineral deficiencies, aging, or systemic illness. Because nails grow slowly and are affected by blood supply and nutrient levels, they can reveal both past and ongoing changes in your body’s internal health. | Facebook
