Semi-permanent hair dye helps to get a rich and bright color. These dyes will help to forget about the pungent smell of ammonia, the appearance of irritation and itching after staining. After dyeing it, the hair becomes shiny and soft. Today, there are various brands of semi-permanent hair dyes on sale, each with its own composition and properties.
Features of semi-permanent dyes
Such dyes appeared not so long ago, but have already gained immense popularity. They are based on special carbohydrate substances. The main thing that distinguishes these from permanent dyes is that they lack pure ammonia. It is replaced by its gentle salt derivatives.
They contain oxidizing molecules having meager sizes. They penetrate the hair shaft. There are also tonic molecules of medium size that settle in the cuticle, giving the curls a different shade.
As a result of staining with semi-permanent paint, these particles are embedded in the natural structure of the hair, while it is not broken. There is a displacement of natural pigments.
The stability of semi-permanent dyes directly depends on the structure of the hair rods. For example, color lasts longer on porous and damaged strands than on hard and healthy ones.
These dyes got their name because with every shampoo, water molecules replace pigments. As a result, the hair color gradually becomes weaker.
Benefits of funds

After about 5-6 head wash procedures, the color is completely washed off. However, there are modern paints that can last 2-3 months. It is also noted that they, although they have a gentle effect, after washing off, it is not always possible to return the original natural color. Molecules that still remain in the hair will react with substances of persistent dyes, which are used in the future.
