What is Ammonia?

Ammonia is a common ingredient in hair color, it’s an alkaline chemical that helps the dye deposit itself onto the cortex of the hair. Typically, ammonia changes the pH level of the hair, and this can weaken strands and cause protein loss. Ammonia is in permanent hair dyes to give the tone longevity, but it’s not necessary in all at-home hair colors.
