I'm having pimples on my scalp for about 11months. I tried using 8x shampoo which didn't work. I was told it is due to mild dandruff. Give me a sol.

See doctor. If u have had pimples (? Folliculitis) on ur scalp for 11 months u shd see ur doctor or a dermatologist. As u may first need a course of antibiotics. Dandruff as well as the associated itching may trigger it and also shd be addressed. Another trigger ( common in India) is daily use of oil on scalp hair which shd be stopped. Good luck. .
