Yeah I've been thinking for the past two years maybe it's my armpits or my ass or something that smells. But I realized it's only my face and scalp because I have a lot of oil on my face. I just never thought it was oil because I didn't have zits. But I smelled everywhere and then one day last month I rubbed my hands through my hair and then smelt it and it smelt bad. I washed my hands, did the same thing on my face and it was bad. It's cause of oil. If you have very dry skin and a dry scalp though you need to put oil on instead of take it off. It's a f**ked up thing but now I'm better knowing it's only my head. I think it's a teen thing because I didn't have this when I was little so hopefully this shit is only a stage.
