Kapalbhati pranayama benefits important uses hair growth

No it does not. No medicine or exercise or yoga can bring back hair. Once the hair follicles are lost then that's it. But having said that I have to say that Shane Warne seems to have got some of his hair back. He did that through a new procedure which transplants hair. Or at least that's what I think it is. Sir Elton John used to go in for a hair transplant before every show as well. So I guess if you want to get your hair back, then you have options but mind you these are all expensive ones.
