Achromotrichia
Definition
A pathological condition or biological phenomenon characterized by the total loss or congenital absence of natural pigment within the hair shaft structure, leading to complete whitening or discoloration. This structural dermatological process is caused by the cessation of melanin production by the melanocytes within the hair follicle, and can be triggered by hereditary factors, severe nutritional deficiencies (such as a lack of copper or pantothenic acid), intense oxidative stress, or autoimmune disorders.
