when bleaching the hair the only answer is "WHITE"
Lighteners / Decolorizing
Lighteners are the chemical compounds that lighten hair by decolorizing the natural hair pigment. Just like color in the tubes. As soon as the lightener formula (powder or liquid) is mixed with the hydrogen peroxide, it begins to release oxygen. This process is known as oxidation, occurs within the cortex of the hair shaft.
Hair lighteners are used to create a blonde shade that is not achievable with permanent hair color , and are called BLEACH.
The lightest color one can achieve using hair color is with the type of color called HIGH LIFT BLONDING. Every line has their own version of HIGH LIFT blonde tones that ‘claim' to lift 4-5 Levels by using this tube of color plus a double dose of 40 Volume Developer.
THE DECOLORIZING PROCESS
· how much pigment the hair has
· the strength of the lightening product
· the length of time it was processed
During the process of decolorizing ( Bleaching), natural hair can go through as many as 10 stages FIGURE 16-20. The most common problem? would be when you see yellow hair..which would mean what? Check the stages....
The hair is never safely lifted past the ‘pale yellow stage’ to ‘white’ with lightener. Going that light with bleach even oil bleach causes excessive damage to the hair strands. One must be a seasoned hair colorist when going into the light blond range....we know how far we can go and be safe...and its nothing you can really 'teach'...... its simply experience!
It kicked ass

Some hair color products may cause a dramatic change in the structure of the hair while others cause relatively little change. Knowing how products affect the hair will be one other feather in your cap so you can make the best choices for your own hair.
A little quick review of hair structure...the hair is composed of 3 main parts.
Hair texture is determined by the diameter of the individual hair strand. Large,medium, and small diameter hair strands translate into coarse, medium and fine hair textures, respectively. Melanin is distributed differently within the different textures. The melanin granules in fine hair are grouped more tightly, so the hair takes color faster and can look darker. Medium textured hair has an average response to hair color product and finally coarse-textured hair has a larger diameter and can take longer to process.
So on the RAZERBURN blog, we just got through teaching the men to determine the 'texture' of their hair - just so they would have the information and knowledge for life...and sure enough here is one other spot that just having the proper diagnosis would be of such a great advantage.
Another aspect that plays a role in hair coloring you must remember is density, which is the numbers of hair per square inch which can range from thick to thin. Density matters as it affects 'proper coverage'.
Porosity is the ability to absorb liquid, porous hair accepts hair color faster and permits darker color than less porous hair. There are different degrees of porosity.....
low porosity: the cuticle is tight>the hair is resistant. which means it is difficult for moisture or chemicals to penetrate & requires a longer processing time. an example of resistant hair ? Gray hair.
average porosity: cuticle is slightly raised, hair is normal and processes in average time.
high porosity: cuticle is lifted;hair is over porous and the hair takes color very quickly <> color also fades quickly
OK... that is now every little tiny bit of info that I was going to have to mention or bring up...in order to explain to explain the world of professional Hair color. Hallelujah!
Whoops it just hit me............
one more day of this.....I need to go Over lighteners.....lighteners such as BLEACH and High Lift Blondes. I love bleaches...as a colourist...I look for the tools that create the most radical change in the hair....that take the hair from black to WHITE.....or from white to black...because to accomplish that well can only be done by handful of people. Its a terrific sense of accomplishment to be the tops in your field.
So stay tuned...I may finish this off today or bounce back to Frizz-FREE FRIDAY....
