"No Poo" simply means washing your hair without shampoo.
Yes, I still wash my hair and no, my hair doesn't stink ;-)
Natural, nourishing, healthy ingredients are what make natural, nourished, healthy hair. The idea that your hair needs chemicals to be healthy is crazy! And frankly, the commercial shampoo marketers are genius to convince us of that.
You'll find everything you need to transition to no poo on this site! Have fun experimenting!
