Uncovering Surprising Solutions for Hair Loss: From Hairy Moles to Aged Skin Pigment Cells.
Scientists have discovered that senescent pigment cells in skin moles can stimulate robust hair growth, challenging the belief that these cells impede regeneration. The study showed that molecules osteopontin and CD44 play a key role in this process, potentially opening new avenues for therapies for common hair loss conditions. The growth of hair follicles is well regulated by stem cell activation; these cells divide, enabling follicles to produce new hair in a cyclical manner. Androgenetic alopecia, also known as male or female pattern baldness, is the most common type of hair loss affecting both men and women.
