Hair colouring is not a new trend. People in ancient times used natural dyes to colour their hair and with the advent of time moved on to chemical dyes. The first synthetic dye was created by the founder of L’Oreal in 1907. Hair colouring provides cosmetic benefit by covering greys and enhancing ones looks.
WHAT IS IN MY HAIR COLOUR?
Permanent hair colours use ammonia as an alkaline agent. Ammonia performs the function of opening up the hair cuticle and allowing the colour to penetrate the cortex. A combination of ammonia and hydrogen peroxide neutralize the existing pigments hence lightening the existing colour of hair, this means that the deposited colour will bee brighter.
HOW IS IT DAMAGING MY HAIR?
Ammonia causes the cuticle of the hair to open by raising the pH of the hair shaft. Protein and moistue escape from the hair shaft due to the opening of the cuticle. Once opened, it is impossible to close the hair shaft. The raised pH of the hair also adds to hair damage. Repeated use of ammonia-based hair colour degrades the hair structure and makes it dry, brittle and unhealthy looking.
ARE THERE ANY ALTERNATIVES?
Most hair colour brands are now launching ammonia free versions of their products. These contain ethanolamine which is safer for use on hair and is known to cause less damage.
