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....
