The most famous and popular means for styling hair is varnish. There are other means, but they are used much less often, without a varnish, almost no girl can do. However, frequent use of lacquer can adversely affect the health of hair, so its quality should be at the level. So what should be a good hairspray?
Modern varnishes are able not only to retain the shape of the hairstyle, but also to look after the hair. They can strengthen the structure of hair and protect them from ultraviolet (this is done by extracts from various plants), supply hair and scalp with amino acids and vitamins, give hair shine and beautiful shade.
Composition
Before you buy a hair spray in the store, it is worth familiarizing yourself with its composition. As part of a good lacquer, there should be no alcohol, as it dries and irritates the scalp (this can manifest as allergies or itching), thinning the structure of the hair. If you regularly use cheap varnish with alcohol, then the hair will become dull, will stick together, and the tips will be split. To reduce the negative impact of alcohol, some manufacturers add special condensing substances to the lacquer.
Make sure that there are substances on the vial label that improve the structure of the hair, for example:
- glycerol (to retain moisture);
- betaine (lends shine);
- panthenol (for recharge of hair);
- benzopheon (for protection).
Absolutely another matter is varnishes with medicinal grasses. They not only shape the hair, but also make the hair obedient and flexible.
At the heart of any varnish is a solution consisting of various resins. Resins can be of both natural and synthetic origin. Also there is a solvent (alcohol or not alcohol). Such a mixture forms a fixative film on the surface of the hair.
The varnish also includes various plasticizers, solvents and film formers. Plasticizers give the hair elasticity, so that the hair is not "petrified".
A very important element in the lacquer is a propellant. With this substance, the hair spray and spray. Previously, freons were used for this purpose, but now they have been replaced by safer substances.
In the varnish at times you can find special colors that give a shade to the hair. Keratin, which is also found in lacquer, is designed to restore the normal structure of the hair, making them strong.
Negative impact
It should be borne in mind that the principle of action of the varnish does not have a positive effect on the hair. Varnish envelops the outer layer of hair, thereby closing the pores. When the varnish dries and "glazes", the hair will become stiff. The varnish clogs the microscopic pores, which means that moisture does not get into the hair deep inside. If we add to this effect the desiccation and thinning of the hair from the action of alcohol, which is the basis of the varnish, then the picture becomes quite depressing.
Very often manufacturers of varnishes promise that their products do not stick together hair. However, all varnishes have this drawback, just the degree of bonding is different for all.
Some varnishes on the label contain information that they impart volume. But in practice this effect is very rarely confirmed.
An important component of the varnish is the smell. It is desirable that it is neutral and quickly eroded. It happens that the lacquers have a very pleasant smell, but this is also not liked by everyone, as the smell of perfume and the varnish can be contrasted with the smell of cosmetics. The odor of lacquer is specific and he will always remind of himself.
There is an opinion that the lacquer protects the hair from the effects of the environment (from the cold including), because it covers the hair with a film. However, this is not so, because in the cold under the influence of lacquer the hair becomes brittle and breaks.
One of the main ways to reduce the negative impact of lacquer - its removal before bed. This can be done by simple neat combing. This procedure removes the film that forms on the hair. If the film is not removed, then over time, the hair will become dull and will look unhealthy. If you have to use a lot of varnish, then in the evening it is better to wash it off.
Therefore, a good lacquer should:
- do not glue the hair;
- easy to spray;
- not to have an odor;
- Do not damage the scalp and hair.
