A new study has found that autophagy plays an important role in activating hair follicle stem cells and keeping the hair growth cycle going. By boosting autophagy, rapamycin improved hair growth in mice and in a human hair organ culture [1]. Round and round it goes The hair leads a cyclical life. First, a hair...

Scientists have successfully regrown hair in a mouse model of hair loss using custom-made plastic microneedles loaded with rapamycin and epigallocatechin gallate (EGCG), an active ingredient in green tea [1]. A hairy problem While not life-threatening or debilitating, age-related hair loss (senescent alopecia) is one of the most conspicuous and hated manifestations of aging. As...

Scientists showed that hair loss happens partially as a result of stem cells escaping from hair follicles. They also shot a stunning time-lapse video of the process. The stem cell cycle Stem cells reside in “stem cell compartments” in various tissues. By differentiating into multiple types of cells upon demand, they contribute to tissue regeneration....

Last week, a new study published in Aging reported similar mechanisms of TGF-ß2 and collagen on hair follicle aging, dermal papilla cell senescence, and in vitro spheroid formation. Aging hair follicles Hair follicles reside in the epidermal and dermal skin layers. At their base is the dermal papilla, where hair growth is controlled by dermal...

Scientists at the Johns Hopkins University reversed hair whitening and loss associated with a high-fat, high-cholesterol diet by using an experimental compound in a mouse model [1]. The compound The experimental compound used by the researchers, called D-threo-1-phenyl-2-decanoylamino-3-morpholino-1-propanol (D–PDMP) acts by blocking the production of glucosphingolipids (GSL), which are lipids that are abundant in the...
