"(...)the best thing is liquid panthenol. It normally comes in foam form for burns, but in liquid form, it stimulates hair growth. It’s actually used in hospitals for chemotherapy patients who lose their hair and have sensitive scalps. My friend recommended that I use it, and my hair grows so much faster now. I put mine in a little spray pump so I can just apply to the roots after I wash my hair and rub it in. I like to leave it in to give my hair a slight lift, which I like, because I have a small head."
