Organix has a full line of keratin products available at most drug stores. They are sulfate free, so they're a little easier on your hair. Sulfates will strip and dry your hair, especially if you color it. It's also paraben free if you care about things like that. Keratin shampoos can build up over time so use something like Neutrogena Anti-Residue occasionally.
I'm excited try this! Finally a MM love that won't be costing me more than I usually spend on something, but must try in order not to miss out on the "deal"!
