Can someone help me treat this redness?

Everytime i got a haircut this redness in my scalp comes out, I’ve been treating this and I already tried a lot of different ointment or shampoos but it still doesn’t work. Please help me this is now one of my insecurity I got this on 2018 and still have them till now.

After getting a haircut, try washing the hair with regular oil or shampoo mixed with two drops of chamomile or tea tree essential oil.

Both these oils are good anti-histamines that reduces rashes on the scalp.

Try a small patch test before applying it on the hair. Since these are natural plant oil extracts, the possibility of any side effects are minimal.
