Nail Treatment for Brittle Nails
Brittle nails, one of the most common nail concerns, cause nails to split, peel, crack, or break easily. While aging, hormones, frequent hand washing, and repeated exposure to water or chemicals are common causes, brittle nails can also be associated with underlying medical conditions, nutritional deficiencies, inflammatory skin diseases, or certain medications. Dr. Dana Stern has published landmark research on brittle nails and specializes in diagnosing and treating the condition.
What Are Brittle Nails?
Brittle nails are one of the most common reasons patients seek care from a nail specialist. If your nails are peeling, splitting, cracking, chipping, or breaking easily, you may have brittle nails.
Weak, peeling nails are not always a normal part of aging. Environmental exposures such as frequent manicures, repeated exposure to water, hand sanitizers, soaps, nail polish removers, and other chemicals can weaken the nail plate. Aging, nutritional deficiencies, certain medications, skin conditions such as eczema or psoriasis, thyroid disease, and repeated trauma to the nails can also contribute. Because there is no single cause of brittle nails, identifying the underlying factors is essential for successful treatment.
What Causes Brittle Nails?
The most common causes and contributing factors include:
Frequent exposure to water (“wet work”), repeated hand washing, and hand sanitizers
Repeated exposure to soaps, detergents, cleaning products, and solvents
Acetone-containing nail polish removers
Trauma to the nails, including aggressive manicures, over-filing, gel or dip removal, and chronic picking
Increasing age, due to decreased lipid content of the nail, hormonal and circulatory compromise
Underlying skin conditions, including eczema and psoriasis
Nutritional deficiencies, particularly iron deficiency and, less commonly, deficiencies of certain vitamins or minerals
Medical conditions, such as thyroid disease or circulatory disorders such as Raynaud’s
Certain medications that may affect nail growth or hydration
Genetic predisposition, as some individuals naturally produce thinner or more fragile nail plates

Brittle Nail FAQ
-
Brittle nails can be due to environmental exposures including products, nail habits, or abrasive tools or from aging, genetics or certain medical issues.
-
It depends on the cause and severity but typically if the treatment is working, fingernails will look improved in approximately 4 months.
-
There are several reasons why brittle nail treatments fail. One of the most common is that the underlying cause was never identified. Another common reason is misdiagnosis. Not all peeling, splitting, or weak nails are the same, and different types of brittle nails require different treatment strategies. Finally, healthy nail growth takes time. Because fingernails and toenails grow slowly, meaningful improvement often requires several months of consistent treatment and addressing the factors that continue to damage the nail plate.
-
Yes. Brittle nails are frequently mistaken for other nail disorders, and an accurate diagnosis is essential because treatment depends on the underlying cause. Peeling, splitting, cracking, and fragile nails can result from normal aging, repeated trauma, nail cosmetic practices, eczema, psoriasis, nutritional deficiencies, thyroid disease, fungal infection, or other nail disorders.
Because many conditions can produce similar nail changes, it is important to evaluate the appearance of the nails, your medical history, nail care habits, and any previous testing or treatments. Dr. Stern will carefully review these factors to determine the true cause of your nail fragility and recommend the most appropriate, evidence-based treatment plan.
-
Usually not. In rare cases where the nails become extremely brittle very suddenly, Dr. Stern will recommend specific laboratory testing. Live video consults include laboratory testing.
