What condition is defined by split or brittle nails?

Onychorrhexis is characterized by the presence of split or brittle nails. This condition often results from various factors, including excessive exposure to water or chemicals, underlying health issues, or nutritional deficiencies. The structural integrity of the nail plate is compromised, leading to visible fissures and fragility.

Understanding this condition is crucial for effective nail care and treatment in a cosmetology setting, as it may require specific interventions to restore nail health. Keeping nails moisturized, minimizing exposure to harsh substances, and addressing any nutritional concerns can help manage onychorrhexis.

Other options listed, such as nail psoriasis, onychomadesis, and onychocryptosis, refer to different nail conditions that involve other symptoms and causes. Nail psoriasis typically manifests as pitting or ridging on the nail surface, onychomadesis involves the shedding of the nail plate, and onychocryptosis refers to ingrown nails. Recognizing the correct terminology and symptoms is essential for effective diagnosis and treatment in cosmetology practice.
