I wash my hair everyday, I just use shampoo no conditioner. After I wash it with hot water, I then scrub-in shampoo let it sit for ~30 seconds, then wash it out. Blow-dry it and then all is well, hair is not greasy at all. And mostly throughout the day it is easy to manager. It's like mid-length, a little past my ears. When I get home from a day it's slightly greasy but not too to bad. I go to sleep and then next morning it is greasy as can be. What am I doing wrong here?
