I wash mine 3 times a week. I used to only wash it once a week. My Mom says 3 times a week is too much. But she only gets hers washed twice a month!!!! And only if she goes to the beauty shop. Her hair is thin and breaks off on the VERY rare occasions when she washes it herself. Mine is long, healthy, and I have very little breakage. We just had a friendly argument about this subject. Plus, she thinks I take way too much advice from this board because since I started coming here, I have been doing alot of things for my hair that I did not do before. Like washing more often,hot oiling, protein conditioning,etc...These are things that my "beautician" NEVER discussed with me.
