Onychorrhexis, also known as brittle nails, describes nails with excessive ridges.[3] As a result, the nail becomes weak, breaks easily and splits at the free-edge.[1]
It is caused by frequent contact with soap and water, and excessive hand-washing.[3] Other causes include frequent use of nail polish remover, and conditions such as hypothyroidism, anorexia, bulimia.[3] Ibrutinib and oral retinold medicines can cause onychorrhexis.[3] It may be normal in the elderly.[2] It may possibly be associated with iron or zinc deficiency, and arsenic poisoning.[1]
Treatment is with biotin.[3]
Onychorrhexis affects up to 20% of the population.[3] Females are affected twice as often as males.[3]
