Deadly Toxic Ingredients in Hair Dye

 DEADLY COLORS

Some people don’t want to show grey hair on their head when they get old; some don’t like the color of the hair they have got from birth; some want to change their hair color according to the characters they act. And some people want to give a different shade to their hair for fun. So, all of them tend to apply hair color or hair dye. Have you ever thought the toxic chemicals in them and their life-threatening side effects?

There are four types of hair colors in the market as:

1.     Temporary hair color (nonoxidative).

2.     Semi-permanent hair color (nonoxidative).

3.     Demi-permanent hair color (oxidative).

4.     Permanent hair color (oxidative).

Oxidative colors are need to be mixed with developer (hydrogen peroxide) and alkaline (ammonia) for oxidation and penetrate through hair, but nonoxidative colors do not want. If you apply type 1) or 2) you don’t want to much worry about that, because they stick around your hair externally and wash out when you wash your hair. So, the chemicals in them are not much toxic and harmful. But if you use 3rd or 4th type, you have to be cautious!

  

Temporary hair colors are direct dyes made up of large molecules and they deposit on the cuticle layer of the hair. Those colors washed away easily when you shampoo your hair. They are non-oxidative and free from developer (hydrogen peroxide) and alkaline (ammonia).

Semi-permanent hair colors also temporary colors which deposit on the cuticle layer. They also need not to be mixed with a developer and no need the action of an alkaline. The stains will last from 3 to 6 washes.                                             

Demi permanent hair die, on the other hand, needs to be mixed with a low volume of developer and the action of alkaline. The stains will last from 25 to 30 washes.         

Permanent hair dyes are made to last long and they contain lots of chemicals. In particular, alkaline chemicals such as ammonia that breaks up the overlapping scale structure of the cuticle by softening them. Then a developer (H2 O2) is used to oxidize the melanin in the cortex, turning it colorless. The developers also create the chemical reaction that brings in the new color to the hair. These new pigments are then trapped beneath the cuticle, and are resistant towards shampoo washes.

SHAMPOO – ARE THEY NICE AS THEY LOOK      Once I had a problem with my hair. There was some dandruff and it gave me a lot of troubles. So, I decided to get rid of it. When I went shopping, I looked for a better brand of dandruff shampoo. I found a bottle of shampoo with a popular brand and bought it.
