I have fine hair and I am addicted to daily co-washing. After every co-wash, I check the condition of my hair to determine if it needs a moisturizing conditioner (B&B w/castor) or something w/a little protein (MNT). Afterwards I seal with castor oil.
I have been doing this for about a year and I am able to do this daily because I wear my hair in a pony tail to work. If I were to style it daily, I don't think I could do it.
During the Xmas holidays, I stayed w/my Mom and couldnt co-wash daily. I was styling my hair ( w/my new CHI
) and we were constantly on the go. My hair was a mess for those 10 days.
This works for me. Good luck...
