You would have often heard of 'Ammonia' in the context of hair colours. But what exactly is Ammonia? Does it harm hair? Can Ammonia free hair colours exist? Can they deliver your desired shade?
Ammonia is a basic high pH material, which is known to be highly irritating to the eyes and mucous membranes. It is used in hair colours to obtain the high pH required for colouring and to facilitate bleaching (lightening) of hair in order to deliver shades lighter than your natural hair colour. In order to bleach the hair, it is necessary for the bleaching agent to penetrate both the cuticle and cortex, as natural hair pigment is buried in the cortex. Ammonia, being a small molecule, readily penetrates the cuticle and cortex, and accelerates and enhances the bleaching effect on hair.
However, during the bleaching process, some of the protein linkages in your hair are broken – this causes damage and loss in hair strength. The damage caused to your hair, in turn, cannot be repaired. Your hair becomes a lot more sensitive to further chemical treatments (such as waving, colouring, etc.), becoming porous and sensitive to humidity. Consumers describe bleached hair as dry, brittle, rough, difficult to comb and more easily broken.
So stop. And think… What does this cost your hair?
Though No Ammonia or Ammonia free colours do not bleach and lighten your hair as strongly as an Ammonia based colour, they help retain the amino acid balance in your hair, causing less damage to your hair. A No Ammonia colour like one of the Godrej Expert range of hair colours, keeps your hair strong, is safe* to use and can lend beautiful, long lasting shades to your tresses.
So, take informed decisions and know your hair colour better, before you colour them lovely shades.
