Although hair loss is not a life-threatening condition, it can be emotionally challenging for those who have it. Current treatments can restore hair growth in mild cases, but are less successful on larger bald areas. Now, researchers report in ACS Applied Materials & Interfaces that they have developed a new technique to culture hair-producing cells in the lab that someday could help hair grow back even better than before. From the earliest known times, people have grappled with hair loss. The ancient Egyptians, for example, would slather animal fats on their scalps to encourage regrowth. Current therapeutic options include either medication or autologous hair transplantation (redistribution of hair by grafting). However, both treatments are only effective for mild alopecia (hair loss) and doesn’t help in forming new hair follicles in the bald scalp.
