What are the ingredients of permanent hair color?
There are two main ones, ammonia and hydrogen peroxide. Ammonia opens the cuticle of the hair shaft so the color molecules can enter. Hydrogen peroxide bleaches the hair so that new color can be added to create the desired shade. Some permanent colors come with more natural ingredients than others, but will likely still have some synthetic chemicals as well.
How is hair color changed?
The hair shaft is like a tube. The outside is the cuticle and inside is the cortex with the pigment. Any applied coloring goes through the cuticle to the cortex, but it may or may not interact with your natural pigment.
If you have dark hair and want it lighter, there are 2 steps: (1) your color is bleached and (2) the new color is added
If you have light-colored hair and want it darker, only step (2) is needed.
Hair coloring is thought of in 3 levels, based on how long the coloring lasts.
· Level 1, semi-permanent hair color – The color molecules are very tiny. They go through the hair’s cuticle into the cortex where your natural color is, but they don’t interact with your natural pigment. Because they’re so tiny, they leave the hair more easily and so this coloring level isn’t permanent. It lasts through about 6 to 12 shampoos. It also doesn’t lighten your hair because there’s no peroxide or ammonia present. Nor does it cover gray more than about 50%.
· Level 2, demi-permanent hair color – The color molecules are again very small and they go through into the cortex. Here, they combine with each other to form bigger molecules. Therefore they don’t wash out as quickly, lasting through a couple dozen shampoos. This type of coloring includes some peroxide, which enables it to subtly lighten the natural shade and blend better with existing gray.
· Level 3, permanent hair color – Again, tiny molecules enter the cortex but this time they react to the natural molecules and expand to a size too large to be washed out. Ammonia and peroxide are both used, so the hair is first lightened, and then colored to the desired shade. Since the final shade is a combination of your natural color and the added color, it will be unique to you.
“Hair coloring has become so popular because it’s so easy to customize,” said Jacquelyn, the office manager at Salon Cabochon in Sacramento, CA. “And so many more men have discovered the fun of changing your hair color once in a while. I mean, why just pay attention to the cut and style? Why not be creative with the color too?”
Hair Coloring Techniques
Selecting the best shade or highlights depends on various factors. It completely depends on facial shape, complexion, haircut, facial expression, eye color, hair length, as well as personal taste. These colors can be various shades and intensity. Depending on intensity or tone colors can be warm or cool. Warm tones are shades of oranges, reds and yellows and cool tones are shades of blues, violets and greens. People who are cool should not use warm tones because that might lower down their features. The best shades for cool people are purple orchid hues, burgundy and lipstick red. People who are warm by nature should preferably use simple gold highlights and golden blondes. Cool tones suit the people with olive complexion and a medium complexion with no pink to a faint pink at the cheeks.
