PROTECTING HAIR CONDITION

When creating a shade of color which is lighter than the natural hair, or when removing
synthetic color from the hair, the product we use MUST BE ALKALINE.
All permanent hair color, hair lighteners (bleach), and color removers.. are alkaline. We
use them with care, as in addition to providing the results we desire, alkaline products do
penetrate into the hair and break down hair stregth. The higher the alkalinity the more
aggressive the product is. So, careful application, processing AND "AFTER TREATMENT
CONDITIONING" are all massively important. While bonders DO minimize potential damage, NOTHING can 100 percent "re-bond" the disulfonic bonds broken down by
application of alkaline substances. Once penetrated with alkalinity, the hair will neverr be "virgin" hair again.
As my dear color expert friend Charles Dudley says: "We can do almost anything to the hair... ONCE!"
So, applying a second batch of lightener to previously lightened hair... may NOT be a
wise decision. Sadly, some people think that using a bonder allows them to repeatedly lighten, then darken, then relighten the hair without damage. NO! Also bleached hair is
NOT the best hair to perm or to relax.... as several highly alkaline services have been
applied to this hair.
Alkalinity is measured by PH. A Ph of 7 is "neutral". and the highest PH level (strongest)
is 14.
Acidic Demi Permanent hair color is approximately at ph of 6.8
Alkaline Demi Permanent hair color is approximately at a ph of 8.0
Permanent hair color is at a ph of 9.3
High lift blonde permanent hair color is at a ph of 10.3
Most hair bleaches (lighteners) and perm solution are at a Ph of 12
Sodium Hydroxide (conventional hair relaxer) is at a PH of 13.5
OVEN CLEANER is at a PH of 14
I hope the information here has been helpful. Summer is "blonding season" so it's time
to be extra careful with these wonderful clients. B
