Oxidation causes the microscopic outer layer of hair follicles to peel back, releasing green color pigments and leaving behind red pigments, and thus producing a reddish undertone that you will see due to the damage.
In the salon, oxidation can be caused by coloring, highlighting, perming and thio straightening, all of which require the use of peroxide, which is an oxidizer. And it's oxidation that causes hair color to fade, lighten and become discolored, and also causes hair to become damaged or broken.
Whenever the hair is exposed to the sun, UV light, chemicals, or hair treatments, hair color oxidation occurs. This can cause the hair to lighten and have a reddish undertone, which is a result of a loss of pigment in the hair shaft, which is in turn caused by the outer layer of the hairs haft peeling away.

Oxidative hair colors are colors, that need an oxidation catalyst (usually hydrogen peroxide) to form a color molecule. Simply we can say, oxidative colors are all colors that are mixed with the developer (oxidant), so-called all permanent hair colors and almost all demi. permanent colors are oxidizing colors.
Box dyes often contain strong chemicals that can over-processed hair, making it dry and brittle. These chemicals can react unpredictably with other hair treatments, causing damage.
Developer typically contains hydrogen peroxide, which serves as an oxidizing agent in the hair coloring process. 😵💫 Easier terms - The dyes in permanent color are tiny molecules…. Add hydrogen peroxide(AKA developer) and that's what creates a chemical reaction(AKA oxidation)🤯
Dark brown refers to the tone of the hair, while ash refers to the undertone. Ash brown hair can be either light or dark, though it's usually on the lighter end of the spectrum.

There is circumstantial evidence that oxidative stress may be a pivotal mechanism contributing to hair graying and hair loss. New insights into the role and prevention of oxidative stress could open new strategies for intervention and reversal of the hair graying process and age-dependent alopecia.
Oxidation is a simple chemical change that can alter the colouring of a hair system over time. It is a direct result of the loss of pigment – specifically green pigment – in the hair shafts, caused by exposure to the elements or chemicals.
