I had experienced severe hair loss 2yrs ago after using a new hair cleanser. 6months after hair loss, no new hair grew back, so I shaved all my hair off, and did not use any hair growth supplements, or hair growth
aids. It has been 9 months since I shaved off all my hair, and up until about 2 weeks ago it all grew back to normal. I noticed hair loss in one of the same areas as when I had used that cleanser. The hair grew back but is now balding again. The other areas all grew back to normal.
