I have read that it's a part of your body detoxing, pushing out the toxic malnourished hair to make way for strong healthy hair to grow in it's place. There's a book called Your Right To Be Beautiful, by Tonya Zavasta, where she talks about the subject of hair loss on a raw diet and how it does regrow. I believe she herself experienced it. She also gives a hair mask recipe that she said helped her. Hope this helps!!
