Lets review what happens when bleaching the hair.
Everyone talks about it, but no one really understands what happens both chemically and aesthetically
Bleach must go through the OXIDATION process in order for the hair strands on top of the head to have the color be removed from them.
By REMOVING the hair color that is in the hair strands it removes the "virgin color" and leaves a color that has become what we all know as the word "BLONDE".
That is why many times, I try to say that the color Blonde...is really not a color that we deposit onto the strands of hair..........we do NOT put BLONDE......."IN"......... in the strands,
what happens chemically and aesthetically is :
Blonde is what is remaining............
once we remove the virgin hair color you were born with.
Oxidation in the de-colorizing process means the hydrogen peroxide is mixed with an alkaline product such as bleach.
Once activated, the de-colorizing mixture changes melanosome structure and lightens the color of the hair. It does this by breaking the melanin into tiny fragments which are no longer able to absorb light to the same degree as before. The melanin does not immediately lose its color when oxidized. The hair goes through relatively predictable color changes as the pigment disperses and lightens the hair to a new level.
( these stages are Brown-----brown/Red-----Red-----Red/Orange------orange----orange-------yellow-----Gold----Yellow------Brass------Pale Yellow)
The following table lists each level of hair color with its corresponding undertone, as well as shades that are achievable at each level.
Chemistry and Effect of Bleaching the Hair
Level Achievable Shades
platinum blonde silver ash blonde ultra pale pastel blonde
strawberry blonde beige blonde tan blonde taupe blonde
honey blonde light copper blonde dark strawberry blonde dark beige blonde
copper redfire red dark blonde
There are no established times for de-colorizing the hair to any given level.
Processing time always varies, depending on:
- strength of the decolorizing mixture,
- use of heat
- type and
- density of natural pigmentation.
TYPES OF DE-COLORIZER
There are three general classifications of de-colorizers used in the salon: oil, creme, and powder. Each performs a specific function, and has unique characteristics.
De-colorizers also include developers and may also include powder activator(s). They are formulated to stay moist during processing in a no-drip consistency. They are popular for their versatile application techniques and are used in both on and off-scalp methods.
Powder de-colorizer are often selected when lighter blonde results are desired on darker natural hair colors. Most powder de-colorizer are for off-scalp techniques, although some do provide the flexibility for on-scalp applications. The pH of powder de-colorizer is approximately 10.5.
There are two basic classifications:
1. On-scalp: Used on-scalp for double processing and off-scalp in highlighting and creative color techniques.
2. Off-scalp: This type of bleach is usually stronger and faster-acting than on-scalp bleaches due to the higher pH and stronger peroxide activity.
Off-scalp is considered highlights, Balayage, etc.. type, techniques.
