i think i messed up my scalp from DIY hair bleaching a couple of years ago, so a dermatologist gave me an LCD shampoo along with an alkaline moisturizer. this will keep dandruff in check for 24 hours but beyond that my head will start itching again. im seeking for a different dermatologist but im afraid theyll all just rope me into buying things that wont really fix my scalp just so i keep coming back to them. what have yall done to fix your own scalp issues?
