Which of the following conditions leads to nails growing in soft and brittle?

The condition characterized by nails that are soft and brittle is known as eggshell nails. This condition results in nails that are thin and prone to breakage due to their reduced strength and structure. Various factors can contribute to the development of eggshell nails, including nutritional deficiencies, overexposure to moisture or chemicals, and certain health conditions.

Understanding eggshell nails is important for manicurists since clients with this issue may require specific care techniques to prevent further damage, such as using strengthening treatments or avoiding harsh products during nail services. This knowledge helps professionals offer the best advice and service to maintain healthy nails for their clients.

The other conditions listed do not specifically result in soft and brittle nails. For example, onychophagy refers to the habit of nail-biting, agnails (also known as hangnails) are small tears in the cuticle area, and nail psoriasis involves changes in the nail structure that can include pitting or discoloration but typically does not lead to nails being classified as soft and brittle. Understanding these distinctions is crucial for providing appropriate care and education to clients.
