Life's a Bleach .. the Lightening of Melanin

Off the Hair Health Horse... back on the Hair Color Horse

Sorry I couldn't figure out why I was sleepy every time I've been posting lately...besides the usual medical crap going on, I was just unusually tired and just couldn't get inspired...I NEED TO WRITE ABOUT HAIR COLOR, to keep me jazzed and alive. So I am just going to have to aaaaside bar6565 alternate the posts, for fear of falling asleep and never waking up. DO NOT GET ME WRONG, Hair Health is as important a subject as there is, I promise you. But, for me I have done all of that writing and reporting... it was completed over the past 6 years  - so its simply a matter of "re-writing" my notes - which I guess is what was pushing the snooze button for me.
I  NEED  SOMETHING  ABOUT  HAIR  COLOR  TO  MAKE ME HAVE TO WRITE  FROM SCRATCH - its what made me become involved - inspired and REJUVENATED once again....something I very much NEED. So back we go. I ordered a couple of new Doll heads . . . Molly & Dolly's cousin's are on their way from back east. If you don't know who Molly and Dolly are . . . SHAME on you -- see here >> http://killerstrands.blogspot.com/2007/12/ble-atched-hair-series-1.html.
They are showing ble-atched- super light blond's well into the Fall - and its the subject I simply get the most questions about... getting to LEVEL 12 successfully & beautifully. So today we are going over the process from a different POV, twisted technical.
Hang on.
Below the surface off the skin is the hair root: above it is the hair shaft.
skin146
The hair root is housed in a sheath, a pocket in the skin, called a follicle. At the bottom of the follicle ( deep in skin) is the hair bulb. Cells that become a strand of hair are produced in the hair bulb, the LIVING PART OF THE HAIR, from which the hair grows. At the base of the bulb, nourishing it, is the papilla, a tiny mound of tissue laced with capillaries.
  hair bulb2
The hair shaft is comprised primarily of cross linked, fibrous proteins called Keratin. Keratin accounts for 90-95% of the hair weight.
Structures in the hair bulb called melanocytes make melanin, or natural pigment. that gives the strand color.2-3% of total weight comes from melanin.
How is hair formed?
The papilla supplies AMINO ACIDS ( remember this - I feel amino acids are important for new hair growth) to the hair bulb; the hair bulb produces keratinous cells; melanocytes infuse melanin into these protein-based cells; then, finally, the cells dry out and harden to form the hair strand ( called keratinization) which emerges from the follicle.
There are 2 types of melanin
  • Eumelanins - the darker pigments from black to brown
  • Pheomelanins - lighter, ranging from red-brown to red-yellow to yellow
All hair no matter what color it is (except white- unpigmented) contains both in varying degrees. Very black Asian hair is heavily pigmented but may contain only eumelanin.
The color of a strand of hair depends on how much melanin it contains, the proportion of eumelanin TO pheomelanin  + the pattern of distribution of the melanin. There are additional descriptions of how these work but truly this all you need to know to understand 'basically' how the hair's VIRGIN color. . .  GOT there!
LIGHTENING OF MELANIN
From your POV, the most important thing to know about melanin is what happens to it in the presence of hair color.  The color result depends as much on the natural pigmentation of the hair as it does on the artificial pigment used; the same ash brown formula may look ORANGE-Y on one natural base, drab on another, and Neutral on a third....something I try my damndest to explain to everyone.

Recognizing what depth the hair is to start with and how it will change tonally when lightened allows you to anticipate the final result. So many of you are so surprised & shocked at your results, which I guess really can only subside with experience. 
Through the years, all the various color manufacturers have come up with ways of getting this process across to hair colorists {and now ME to you }  . . . . but the point of any theory of lightening is to drive home the idea that the color result depends on MORE THAN WHAT YOU put in the BOWL - -  it also depends on the color contribution of YOUR hair on your head.  So no matter how many rules we come up with and no matter how many different ways we try to teach lightening of the hair, going from Level 6 Brown Hair to that rocking Level 12 that you have always wanted to be. . . .  it also depends on the color contribution of that hair on your head right now.
Natural color contribution depends on:
  1. the original virgin color &
  2. how much you lighten it
The natural base level and the lightening capability of your formula, determine the color contribution of your hair.
The color contribution of the hair AND
the artificial pigment used...determine the color result.
Natural color
+ lightening capability of the formula
= the color contribution of the hair
AND
The color contribution of the hair
+  the artificial pigment
= the Color result

Are you getting this...??  Color contributions of the hair is referred to any one of different ways: undertones, underlying pigment, natural  underlying pigmentation, pigment bases, residual pigment contribution, natural contribution of the hair, lightened natural pigment and remaining natural color.
Any of these term can be substituted in that last equation (above).

SEVEN STAGES OF LIGHTENING
This concept concerns the color changes that happen when hair is exposed to a product capable of lightening it.
One of the best lessons in hair coloring is how the FINAL Result depends as much on the natural contribution ( remember what YOUR hair has IN it naturally - as it was when you were born) of the hair a s it does on the artificial dyes, and the seven stages of lightening is a way to tell that story.
The 7 stages of lightening are the colors that hair attains as it is lightened with either permanent hair coloring or bleach.
If hair bleaching could be viewed in super SLOW MOTION, these are the tonal stages that would be seen during the progression from dark to light.
The 7 stages of lightening are:
  1. BLACK
  2. BROWN
  3. RED
  4. RED-GOLD
  5. GOLD
  6. YELLOW
  7. PALE YELLOW
  When hair is exposed to a lightener agent, its black and brown pigments are first to begin to break down or oxidize ( the eumelanin lightens first). Then the red & gold pigments gradually oxidize  - then yellow and pale yellow stages are simply lighter and lighter version of gold.

Notice 5 of the 7 stages have to do with red and gold, this is due to the tenacity of these colors in the hair. In other words, they are IMPOSSIBLE to get out of the hair! It takes longer to eliminate Red and forever to eliminate GOLD. I am hoping you will all relate this to your experience of being stuck in the "gold" stage as though it seemed like FOREVER 
The most sought after goal when going Gwen Stefani BLOND . .Pale Yellow, I refer to it as frozen butter. Pale yellow is the lightest hair can become without destroying the hair. Pale Yellow can be toned to be almost any color on the planet...including white.
I am hoping with this series in the long run I will see less banana-heads on the street, realizing fully what a grand wish that is, I am still hopeful - they make me shiver.gwen99
There are 3 parts to this  Post. . . I will finish it in the next 8 days. . . . so stay tuned!
