    The Hairless Gene, often abbreviated as HR gene, is a gene that plays a crucial role in the regulation of hair growth and development. Mutations in this gene can lead to conditions such as congenital atrichia, where individuals are born with hair that is subsequently lost and not regrown, resulting in permanent hairlessness. This gene is essential for the normal cycling of hair follicles and the maintenance of hair.
