Which nail condition involves increased thickness and curvature to a degree?

Onychogryposis is characterized by an abnormal thickening and curvature of the nails, often causing them to become deformed and claw-like. This condition can result from several factors, including aging, trauma, and various systemic diseases. The increased thickness of the nail plate can lead to discomfort and difficulty in nail care, as the shape can make proper trimming and maintenance challenging.

Understanding onychogryposis is essential for cosmetologists, as it emphasizes the importance of recognizing various nail conditions that can affect clients. This knowledge helps in determining appropriate treatment options and advising clients on proper nail care. It also highlights the necessity of discussing any underlying health issues that may contribute to such nail changes, ensuring that clients receive comprehensive care and advice.
