How Hair Dye Works

Hair dye works by penetrating the hair shaft and altering its natural color. The different types of hair dyes include permanent, semi-permanent, demi-permanent, and temporary options.

Permanent Hair Dye

As the name suggests, permanent hair dyes produce long-lasting results. They use a combination of ammonia and hydrogen peroxide to lift the hair cuticle and deposit color deep into the hair shaft.

Semi-Permanent Hair Dye

Semi-permanent dyes do not contain ammonia and only partially penetrate the hair shaft. This results in a less permanent color change that gradually fades over several weeks.

Demi-Permanent Hair Dye

Demi-permanent dyes use a low concentration of peroxide, providing color that lasts longer than semi-permanent options but is not as permanent as the traditional ones.

Temporary Hair Dye

Temporary hair dyes coat the outer hair shaft and do not penetrate the cuticle. They are easily washed out with shampoo and are ideal for short-term color experimentation.
