TLDR Fat tissue around hair follicles releases a growth factor that helps hair grow and develop color.
The study by Nicu C et al. demonstrated that dermal white adipose tissue (dWAT) surrounding hair follicles (HFs) plays a crucial role in regulating human hair growth and pigmentation through HGF/c-Met signaling. This finding suggested that targeting HGF/c-Met signaling in the perifollicular region could offer a novel therapeutic approach for treating disorders related to human hair growth and pigmentation.
