Toxic ingredient - Ammonia in hair color

 

What is the purpose of ammonia in hair colour?

The purpose of ammonia in hair dye is to help open up the cuticle layer of the hair to allow the color molecules to penetrate the hair. It also serves as an activator to peroxide in the colour developer and helps to form the color in the hair. Some formulas replace the ammonia with other alkalines to fulfil the same function.

What is ammonia?

Ammonia occurs naturally and is produced by human activity. It is an important source of nitrogen which is needed by plants and animals. Bacteria found in the intestines can produce ammonia.
Ammonia is a colorless gas with a very distinct odor. This odor is familiar to many people because ammonia is used in smelling salts, many household and industrial cleaners, and window-cleaning products.

Ammonia gas can be dissolved in water. This kind of ammonia is called liquid ammonia or aqueous ammonia. Once exposed to open air, liquid ammonia quickly turns into a gas.
Ammonia is applied directly into soil on farm fields, and is used to make fertilizers for farm crops, lawns, and plants. Many household and industrial cleaners contain ammonia.
It is on the CERCLA priority list of hazardous substances.

How can ammonia affect my health?

No health effects have been found in humans exposed to typical environmental concentrations of ammonia. However, exposure to higher levels of ammonia in the air may be irritating to your skin, eyes, throat, and lungs and cause coughing and burns. Lung damage and death may occur after exposure to very high concentrations of ammonia. Some people with asthma may be more sensitive to breathing ammonia than others.

Swallowing concentrated solutions of ammonia can cause burns in your mouth, throat, and stomach. Splashing ammonia into your eyes can cause burns and even blindness.

Ammonia is believed to be one of the main chemicals to cause respiratory disorders in hairdressers.

Brunettes and Color

Being a hot brunette, especially a fake one involves a lot of work. First of all the color needs a good shampoo and a good conditioner for colored hair to maintain that healthy fabulous look. When the color starts to fade she can use a shampoo and conditioner with color pigments to add that little extra to boost the fading color. When the natural color starts showing close to her scalp she needs more serious work. Of course she wants an even tone all over her hair so she tints only the roots, because if she adds color to her whole hair she will end up with black ends and brown roots. Make sense?

So she adds the color only where needed, the roots, and when the color is processed she quickly rinses her hair so that it is damp all the way through before massaging up a lather from the color. This lather and that last tiny tiny bit of color from the bottle is massaged through her hair and then combed through, then massaged again. It sits for about 5 minutes before she rinse her hair again this time using shampoo and conditioner, for colored hair of course!



Why will the ends be darker if color is added on all the hair instead of only the roots?

If you think about it as simple math. Already dark color+more color=very dark color.
What most people say now is "but my ends are all faded and needs more color" well, do they need as much color as the roots? No they don't, and if they are really faded use a waterbottle to spray the hair after half the processing time and then add color to them. This weakens the color but still allows it to process chemically and therefore touch up.
