The Ordinary Glycolic Acid 7% Toning Solution

yes great go for it... acids should use it on dry scalp/skin . Apply with the help of nozzle and massage gently on the root hair, leave it for 15 minutes then rinse it off with regular shampoo. I warn you that it makes hair lil dry don't forget to use conditioner or any hair serum just avoid in the roots

part your hair first for easier application and apply it on the roots !

I have done it as a sort of scalp mask and it works great for me! as a cyclist, I wear a helmet a lot, and my scalp is always crammed up and sweaty 😩 I was worried about clogged hair follicles, so I saturated a small cloth and dabbed it onto my scalp. left it fir the usual mask time, 10-20 mins and then rinsed it out with regular shampoo and conditioner. My hair felt so much fluffier at the roots. would recommend, but probably not more than once per week or so.
