GlossaryBrittle Nails

condition where nails easily split, crack, or break

Brittle nails, also known as onychoschizia, refer to nails that are prone to splitting, cracking, or breaking easily. This condition can be caused by various factors, including frequent exposure to water or chemicals, nutritional deficiencies (such as low levels of biotin or iron), and underlying health issues like hypothyroidism or psoriasis. Proper nail care and addressing any underlying health concerns can help improve nail strength and reduce brittleness.
