"If a woman is in her twenties and thirties and losing a lot of her hair, what's happening is often too little stomach acid and pepsin. Because of that, protein isn't digested, and - what is hair made of? You got it...protein!
"Now with women in their forties who are losing their hair, most often it's a combination of low stomach acid, low thyroid, and, of course, sex hormone loss - mainly estrogen and progesterone. In this case, we replace missing hormones with bioidentical estrogen, progesterone, and thyroid. Then we also replace the missing or low hydrochloric acid. But there is one more element on the outside track - DHEA." - Dr. Jonathan Wright
