Hi - how long does the keratin treatment last that you are offering with groupon? Thanks, Cynthia

The Keratin treatment last up to 3 months providing you use a salt free and sulfate free shampoo. There are also NO toxic effects. You can also wash your hair the next day. The more you use the Keratin the longer it last.
