The Science of Healthy Hair, Hair Loss and How to Regrow Hair
Huberman Lab
In this episode, I explain the biology of hair, hair growth, why hair growth slows and what causes hair to stop growing and/or “fall out.” I discuss the essential role of hair stem cells and other supporting biological factors for healthy hair growth. Then I describe various approaches (mechanical and chemical) to slow hair loss by increasing blood flow to hair stem cells, including minoxidil, tadalafil, PRP, microneedling, Botox and ketoconazole treatments. I also discuss how age-related hormone changes cause hair loss and explain the effectiveness of treatments such as caffeine, saw palmetto, growth hormone, finasteride and dutasteride. For all hair growth options, I describe potential side effects, how soon to expect results and the amount of hair regrowth to expect and I highlight effective combination treatments for hair regrowth even in hair “dead” (bald) zones. For many listeners, thinning, brittle hair, or pattern baldness are a source of anxiety and stress. This episode explains the mechanisms underlying hair regrowth tools and the science behind them so that you can evaluate potential treatments and associated side-effect profiles and select the best one(s) for you.
