Dry or Brittle Nails
Hands | Dermatology | Dry or Brittle Nails (Symptom)
Brittle nails also known as Onychorrhexis, meaning that the nails easily become cracked or chipped, can be observed as a sign of aging or in response to the long-term use of nail polish or exposure to moist conditions (including frequent swimming or dishwashing).
Many medical conditions can affect the shape or texture of the fingernails. Some diseases are also associated with changes in the nails, which can include brittleness. The term onychoschizia refers to splitting of the fingernails as well as brittle or soft nails. Taking biotin (a vitamin) supplements can help in some cases of brittle nails, and application of moisturizers after soaking in water can also be of benefit.
It may result from excessive strong soap and water exposure, nail polish remover, hypothyroidism, anemia, anorexia nervosa or bulimia, or after oral retinoid therapy. Onychorrhexis affects up to 20% of the population.
