The Science of Healthy Hair, Hair Loss and How to Regrow Hair

About this video

Huberman explains the biology of hair, arguing each strand has its own stem cell niche in the follicle that produces hair for different durations: head hair can grow for four to six or even eight years, while eyebrows grow only for months. He covers what determines hair length and growth cessation, hormone-related hair loss in men and women, mechanical and stress influences, and approaches including minoxidil, dutasteride, ketoconazole, microneedling, and thyroid, estrogen, and IGF-1 pathways, while dispelling the myth that balding patterns are simply inherited from one’s mother’s father. In the excerpted segment, citing a systematic review of microneedling for hair loss, Huberman says microneedling appears to benefit men and women especially combined with other treatments, and that combining microneedling with minoxidil is far more effective than either alone, including in recovering so-called dead zones over long periods.
