This is a deep-cleansing shampoo which has just the right pH value to open the outermost layer of the individual hair strands (the cuticle layer), which prepares the hair for the next step in the keratin treatment. Our Shampoo Opener is an important part of the treatment when you want a long-lasting result, and therefore cannot be replaced with other shampoos.

How to use it:

Rinse hair and apply a small amount of Shampoo Opener. Make sure to massage the shampoo thoroughly into the entire hair. Now rinse the shampoo out of your hair and repeat the process. Rinse hair thoroughly after second application
