This restorative, in-salon intensive treatment repairs, strengthens, and improves the elasticity of hair in 4 minutes. Used post-chemical service to repair damage incurred during the service. K18 Professional Mask is a post-service part of our 2-step in-salon service or can be used as a stand-alone treatment for clients. This mask was engineered to repair damage caused during any salon service. With a pH of 5.0-6.0, the leave-in mask helps to close the cuticle and seal in the peptide to reconnect broken keratin chains, with added lightweight conditioning benefits to keep hair smooth and soft.
