April 2019 in “Journal of Investigative Dermatology” This study reported that gain-of-function mutations in TRPV3 lead to hair loss in mice by disrupting inner root sheath keratinocyte differentiation, ultimately causing follicular keratinocyte stem cell exhaustion and permanent follicle disruption.
April 2017 in “Journal of Dermatological Science” In this study, researchers found that in adult mice, new hair follicles with pigmentation can regenerate from the epidermis after skin wounding, aided by melanocyte stem cells moving from nearby existing hair follicles.
