i keep mine cut so short there really wouldn't be a need to wash it, but I still do, daily. you dirty fuckin pigs
If you actually are able to tolerate the greasiness for a few days, start to space out the time between washing your hair. Your hair *will* adapt and start getting greasy less fast. It is only because you wash your hair so much, that it works extra hard to keep it's essential oils.
I only wash my hair like once every 5 days during the summer, but during the winter, grease hangs in the air more thickly at my job, so I have to wash it closer to every 3 days. I'd probably go longer, but I live with smokers who don't care if the whole house, their clothes, their things, MY things smell like smoke, so I have to wash that stink out. *sigh*
yeah it's not much of a question on washing my hair persay, but i do have to wash my scapl because if i don't it gets all itchy and then if i don't scratch it it drives me crazy, and if i do i look like i got lice. so i just go one and wash my hair/scalp, like once every 3-4 days.
