We all know that permanent hair color is also known as. oxidative hair color. That
is because the presence of oxygen.. and an oxidizing agent (peroxide) must be
present in order for the color to develop.
The chemical notation of hydrogen peroxide is H2O2. Two molecules of Hydrogen
mixed with two molecules of Oxygen. When peroxide is mixed with oxidative
(permanent) hair color, the peroxide acts like a "fuel". -- compare this to how
gasoline "fuels" the motor of a car.
As color develops, the peroxide begins to break down... and after about one hour, the
H2O2 becomes... H2O.. WATER! And, water no longer "fuels" that motor.. that "engine"
of permanent hair color. While some marginal deposit of tone might continue after
45 minutes to 1 hour. the simultaneous and effective "lift" and "deposit" involved in
the coloring process stops.
But that one oxygen molecule that separates from the original H2O2, does not simply
vanish. It becomes a negatively charged oxide.. or "free radical"... which modifies
the condition of the hair. According to hair color guru, Max Maisano, that free radical
spins out of control and creates what's known as reactive oxidative stress.. damage.
This is why Max and I have always agreed that a post color acidic treatment is absolutely
required when rinsing and shampooing hair color from the hair. I'm delighted to share
that Max will be joining Damion and I in class on Monday, July 24th in Naples, Florida.
We look forward to seeing you there! B
