Ammonia negatively affects the cuticle of the hair, it also damages an amino acid or protein called tyrosine which is found inside the hair shaft. Tyrosine is responsible for producing melanin (the natural pigment in the hair shaft). When the Tyrosine is damaged the hair’s ability to hold onto color is greatly reduced or eliminated altogether, so big THANK YOU TO Loreal!!!
