Keratin, as a treatment or an ingredient

Keratin treatments glue protein onto the hair, a treatment we highly discourage. Although the Keratin is the same protein as your hair, it prevents Hairprint from working. It cannot be removed by our Pretreatment Shampoo or a Clarifying Shampoo. 

If you have had a keratin treatment on your hair, wait at least 2 months for it to naturally dissipate before applying Hairprint. Also, please note, it can last as long as 6 months on your hair.

If you have keratin listed as an ingredient in your hair care product, please discontinue use and wait 3 weeks before applying Hairprint. 

Please read our Hair Residue FAQ to learn about more hair care product ingredients that may prevent Hairprint® from working properly.
