Why does this happen

Girls help

Does anyone else’s hair after sex get greasy? I can shower wash my hair have sex and boom it’s greasy again 🙄 I don’t sweat a lot I’ve tried that theory I can have my hair up fan on and it still happens & it’s just super annoying now bc I feel like I can’t have sex in the daytime if I’m planning on going anywhere after bc the damn thing gets greasy so quick.

Any tips ?
