I love me some DIrTy Hair! I mean for coloring and updos mainly. It makes coloring hair, and styling hair much easier. The foils and backcombing can really grip to the hair, and allow a better foundation for us as stylists to work with. A BIG Thank you to all of you who so kindly come to your appointments with dirty hair. Dirty as in a day or two without washing- Please don't assume you are doing your stylist a favor by coming in after 2 weeks without washing your head. When the shampoos isn't sudsing, we have an issue with hygeine.
