Proteins in Shampoos and Conditioners

Proteins in shampoos and conditioners can last from a few days to a few weeks depending on the size of the protein and how it is applied. Smaller proteins will lodge inside the cortex of the hair and larger proteins adhere to the cuticle.

Please discontinue products containing these ingredients and allow a waiting period of 10-14 days to ensure that most of the protein has been eliminated from your hair before applying Hairprint.
