Hair Dyes – Natural dyes – How they work? Characteristics and Types

Hair Dyes

Hair dyes are used for coloring gray hairs and sometimes simply because you love to change your look.

Human hair has its color, which tends to fade over time and turn to gray and white.

In many cases, you can start to have gray hair when you are still relatively young, so many people, especially women, decide to dye it.

Hair dyeing can be done in two ways by coloring the hair or by bleaching it.

Coloring occurs when natural color or gray is covered or when you want to restore a faded natural color following aggressive treatments.

Conversely, discoloration occurs when dark hair is lightened or bleached.

There are so many hair dye products, but essentially they are divided into three types: creams, gels, or coloring shampoos.

They can also have the purpose of coloring the hair in a temporary, semi-permanent or permanent way.

Temporary coloring is possible using a shampoo that includes coloring substances that do not penetrate the hair but merely lean on it.

Thus, it should commonly use these products often because the color fades as soon as you wash your hair.

On the other hand, the semi-permanent coloring lasts longer on the hair; in general, it can last up to 8 washes.

The dyes used to obtain a semi-permanent color cannot lighten the hair, but they can cover gray and white hair.
