Talk to Dermatologist on Dermatologist Hair Skin

I want to know about my condition. Pic is attached. I have itchy bumps all over my scalp since 03 months. Before this and before getting bald, I was facing severe hairfall on shaking our even gently pulling them. White flakes come out of my hair when I shampoo. I also have acne on my cheeks, face, scapula and shoulder. Is this folliculitis ? I was prescribed Fuscidic acid cream for the bumps in my scalp previously and doctor said it is a skin infection. But apparently it didn't work. I stil have these bumps.
