The Huberman Lab Podcast discusses neuroscience: how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health. We also discuss existing and emerging tools for measuring and changing how our nervous system works. Dr. Andrew Huberman is a tenured Professor of Neurobiology and Ophthalmology at Stanford School of Medicine. His laboratory studies neural regeneration, neuroplasticity, and brain states such as stress, focus, fear, and optimal performance. For more than 20 years, Dr. Huberman has consistently published original research findings and review articles in top-level peer-reviewed journals, including Nature, Science, Cell, Neuron, and Current Biology. He is a regular member of several National Institutes of Health review panels and a Fellow of the McKnight Foundation and the Pew Charitable Trusts. Dr. Huberman regularly consults for technology development companies, professional athletic organizations, and various units of U.S. and Canadian Special Operations.
The Science of Healthy Hair, Hair Loss and How to Regrow Hair
In this episode, I explain the biology of hair, hair growth, why hair growth slows and what cause 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.
