Back in the 1950s, just 7% of women had their hair colored.
Compare that to 2015, the percentage ofwomen with colored hairhad increased to roughly 75%.
Then there are those who put their dye in hair conditioner.
But, why is this even necessary at all when dyeing your hair?
This is more of a concern when dealing with bold and electric colors.
The ammonia is responsible for raising the PH of your hair when you apply the dye.
That way, your hair cuticle opens up easy and allows the dye in.
