So as a non dread-head myself, I use a decent amount of silly products in my hair and after a time you can really feel the build up. Well, a few times now I've used Gilly's nag champa shampoo bar to wash my own hair and then not combed it out after and just let it air dry.
I'm some one with normally very straight (SUPER processed... I've been dying it loads of colours for years) hair and I cant tell you how many compliments I get on those days I've washed with dread shampoo. It gets all light and curly and so so so soft and you can tell it's just clearing out all the gunk that builds up.
So spread the word to your non-dread friends!!!
