I can't keep my hair from becoming greasier throughout the day. I only use conditioner every three days & it's still greasy!
Does anyone have any tips on how to stop this?
Well, I´ve got the same problem... what I do to avoid this is wash AND condition my hair everyday. But when you apply the conditioner, do so only in the lower half of the hair, avoiding the scalp, which is likely the most greasy area in your hair. Do this in the morning, or before you got to sleep, then towel-dry, and let air do the rest... or you can use an air/blowdrier if you wish. This is my routine, and it works wonders for me.
Good luck! Hope it helps!
