I have male pattern baldness and believe there is nothing which helps my hair to regrow other than transplantation. I am living in the UK (Indian origin with black hair). As said, I am using this Loreal Thickening (Regenium-XY) just to reduce hair fall. I use it 4 to 5 times a week. Now, I feel like using a conditioner along with it. Could anyone reccommend me one which is chemical free or something which isn’t harsh on hair. Any other reccommendations to keep hair healthy ?
