Science Daily: Blocking enzymes in hair follicles promotes hair growth - Two FDA-approved drugs reawaken dormant hair follicles

summary - Inhibiting a family of enzymes inside hair follicles that are suspended in a resting state restores hair growth, a new study has found. In experiments with mouse and human hair follicles, researchers found that drugs that inhibit the Janus kinase (JAK) family of enzymes promote rapid and robust hair growth when directly applied to the skin.
