What condition involves periodic shedding of the nail on the finger?

Onychoptosis refers to the periodic shedding of the nail on the finger. This condition can occur due to various factors, including trauma, certain diseases, or underlying health issues. In cases of onychoptosis, the nail may separate from the nail bed, leading to what appears as partial or complete loss of the nail.

Understanding onychoptosis is essential for nail technicians, as recognizing the signs can help in advising clients on their nail health and determining when professional medical advice may be necessary. It is also valuable for nail technicians to be aware of the factors that can contribute to this condition, as it underscores the importance of nail care and maintenance.

Other options, while related to nail health, do not pertain to shedding nails. For instance, onychorrhexis involves the brittleness of nails leading to longitudinal ridges and splits, and onychophysis refers to the thickening of the nail plate. Psoriasis is a skin condition that can affect the nails but is primarily characterized by scaly patches of skin rather than periodic shedding of the nail itself.
