Well I work in a factory where I have to wear ear plugs constantly. But, I bleached and dyed my hair a couple days ago and it's been nothing but a mess. My scalp is irritated and has scabs where I bleached and colored it at. I've been applying peppermint oil to it to ease the itch but I don't know what else to do to actually help it heal. Also my ears have been slightly itchy on the inside and in the canal, and I have a small bump/lump/cyst (?) behind one ear, what could that be? Please help.
