Hydrogen Peroxide / Developers Let me bring the concepts down … to the planet, a lot of this may seem unnecessary and strange sounding but everything needs to be taught and understood for those of you wanting to professional hair-habits-and-how-to-break-them/” title=”The Worst “Bad Hair Habits” and How To Break Them”>hair color at home front. All of the info talked about, needs to be said …so I can refer to it as I head deeper into teaching hair coloring at home, be patient. If you want to learn information that would cost a tremendous amount of $$ plus years of experience, just read and re-read every post. I am teaching all our secrets – I don’t know a soul that would do that.} Getting down to the nitty-gritty > to make a batch of haircolor to put on hair, this is the picture: You have a bowl…a tint brush …on one side of the bowl is some color ….squeezed out of a tube…on the other side of the bowl…..Is the “white stuff”…..which has no smell until the 2 substances are combined…then POW- mix the 2 things together and it explodes in aroma and changes hair color . That white stuff is the Developer …or Hydrogen Peroxide. I snicker when I hear that some new hair color is great & wonderful because it doesn’t use peroxide. To me….as a chemist….as a Colorist…the last thing on the planet I would want would be a hair color that does NOT have hydrogen peroxide in it ! The only hair color that does not work with Developer is SEMI-Permanent Hair Color A developer is an oxidizing agent that, when mixed with an oxidative hair color, supplies the necessary oxygen gas to develop color molecules and : create a change in hair color Developers, also called oxidizing agents or catalysts, having a pH between 2.5 and 4.5 . Although there are a number of developers on the market, hydrogen peroxide (H2O2) is the one most commonly used in hair color. VOLUME is the measure of the potential oxidation of varying strengths of hydrogen peroxide. The lower the volume, the less lift is achieved; the higher the volume, the greater the lifting action. The majority of permanent hair color products use 10 ,20,30,40 Volume hydrogen peroxide for proper color development. One of the best little tricks in the world of developer are TINTED versions, in other words we have Blue and Violet Tinted Developers in 20 And 40 Volume which helps when needing any sort of warmth reduction ( too much brass/blorange/Gold) if those are your problems give either Blue or Violet Developer a try.
