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 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. For the full show notes, visit
