How Do Hair Dyes Work?
Hair dyes are classified into four: temporary, permanent, demi-permanent, and semi-permanent.
This classification is based on the hair dye`s ability to sustain the color of hair. Demi-permanent and permanent dyes are made up of oxidizing agents which react with the existing hair color to form a new shade.
Temporary and semi-permanent dyes work by coating hair strands with color.
While temporary hair dyes only coat the hair cuticles, semi-permanent dyes can be absorbed into the hair cortex. Because these two hair dyes only work by coating the hair dyes they are referred to as non-oxidative hair dyes.
With temporary, semi-permanent, and demi-permanent dyes it is possible to get rid of the color after several washes depending on the dye type.
For permanent dyes, however, the color remains on hair unless the hair is cut. The roots however will grow in your natural hair color therefore constant retouching is necessary to maintain the color.

How To Dye Hair Safely
The following tips are essential to follow to keep yourself and your hair safe during the hair dyeing process.

The safest bet when it comes to using hair dye is to keep to the instructions.
Especially when switching from one hair dye to another, the instructions might not apply.
It is therefore important to observe caution and pay attention to detail throughout the whole hair dyeing process.
3. Use protective gear
To protect other parts of your body from the dye, it is important to wear the required protective gear.
In line with the first point, the instructions will always show any necessary gear and equipment you need.
A good staple is a protective glove that protects your hand from chemical harm and discoloration from the dye.
4. Avoid mixing dyes
Different hair companies have different sets of ingredients that make their products.
Mixing hair dyes means risking possible chemical harm arising from these chemicals mixing up violently.
It is advisable to use products or a treatment plan from the same provider to reduce any chances of chemical harm to your hair or scalp.
