HAIR LOSS - that's an understatement. Mine has been coming out in handfuls. I've always had thick, wavy, long hair and now I can see my scalp like an old lady - I'm only 35 ! I had no idea what was wrong. Stay away from this stuff unless you want to look like a billards ball ! Even at $100+ a bottle, mine's in the trash. There should be a warning on this !
