Question

what are the hair shaft or hair dye keys​

Answer 1

$\large\mathbb \blue{\fcolorbox{blue}{black} { \ HERE\ IS\ YOUR\ ANSWER \ }}$

• For hair dye pigments to enter into the hair shaft, it needs some type of catalyst to open the cuticle layer of the hair shaft.

• Ammonia is used in hair color. This chemical elevates the pH of the hair, and in doing so, the cuticle relaxes and lifts up. Once the hair cuticle is raised then the color pigments can enter the hair.

• Ammonia-free colors mostly work by using an ammonia alternative called MEA, or monoethanolamine, or an oil-based delivery system, to more gently open and penetrate the hair shaft.

• As far as a hair color developer goes, developers are the oxidizing agent that allows the hair color to do its job. Most permanent hair colors today uses hydrogen peroxide as a developer.
