I voted a month, because I have officially been regularly pooing/cowashing/dcing for exactly a month, and I feel as if my hair has benefited so much! I have definitely noticed a big difference! I never used to before because I was under the impression I could not handle my hair, or that I just didn't know what I was doing.....I feel so much better about my hair now. Of course, I'm still kicking myself about not taking better care of m hair in the past, and the fact that I let my hair suffer for so long, but after this past month, I swear my hair is different!
