Hair cosmetics are packaged in different types of containers: bottles, jars, tubes, ampoules, etc. We strongly recommend using the factory packaging.

If you use filling in other (non-factory) types of packaging, under the influence of external factors, cosmetics lose their consumer qualities inherent in the manufacturer. If you buy cosmetics on filling, you should use them as soon as possible.

Cosmetic products are divided into many types: keratins, botoxes, restoratives, masks, shampoos, conditioners, etc. This characteristic shows which type a particular product belongs to.

Professional hair cosmetics are used to achieve different results. Depending on the problem and the preferences of the end users (customers).

Some need to straighten the hair for a long time, others prefer only to restore the hair after various chemical influences, others need shine or moisturizing, and the fourth all at once. 

Some cosmetic compositions are aimed at solving narrow problems, such as just straightening. Some products are more versatile and combine both straightening and restorative and other functions. 

Based on the needs and the desired result, the necessary complex is selected. 

Most professional salon hair treatments are recommended from the age of 18. This is due not only to possible allergic reactions, but also to the fact that the hair of young people in most cases does not require serious professional intervention or correction.

For those under the age of 18, there are other, safe and revitalizing hair spa treatments. Pay attention to the recommended age of application when choosing a cosmetic product.

Most professional cosmetics for hair, have a high concentration of oils, preservatives and other active ingredients that can cause allergic reactions. Such products should not be used during pregnancy and lactation.
