I don't use any product and haven't since dance concerts many moons ago. Have naturally straight, darkish brown hair and usually only wash it once a week as is. I did colour it (blonde, of course haha) for almost my entire senior schooling but has been its natural colour for ages now. It actually isn't looking bad at the moment, it does feel a little oily though. Hmm maybe I should stick it out, no big events on the calendar as such, do a little experiment... for science...
