Have you tried a honey and molasses treatment? I used to do this until my hair started getting too soft (over-conditioned).
I'll warn you, it is very messy and smelly, but it really works. Coat your hair with honey,molasses, or a combination of the two, put on a plastic cap for at least an hour, then rinse thoroughly.
YES WE CAN!
