i agree...ur hair will decide for u. U wont know til u try. Start off small then work ur way up to 3x a week. The more u do it, the more u'll be able to tell
I also agree with the ladies above. It solely depends on your hair...all methods of hair care are different from another and how it effects our hair. I can CoWash 5x times a week which can be extremely too much for your hair. Rely on your hair's response.
