29 Jun 2022 --- New hair follicles are produced as a result of an interaction between immune cells called regulatory T cells and skin cells that use a hormone as a messenger: improving hair growth, discovers US-based researchers at Salk Institute for Biological Studies. They suggest that the discovery may be applied to treat alopecia, a condition in which an individual's immune system destroys their own hair follicles, resulting in hair loss.This study showed that regulatory T cells and glucocorticoids have a regenerative effect on hair follicles, in addition to being immunosuppressants.
