Today such procedure as keratin hair straightening is very popular. The essence of this method is the elimination of electricity and smoothing the cuticles with the help of liquid keratin. Keratin straightening helps to make the hair more manageable, healthy and silky. After the procedure is done, you can forget about hair problems for 3-6 months.
The purpose of keratin straightening is to restore distorted curls and make them aesthetically pleasing and manageable. Basically, the hair is subjected to deformation due to the negative influence of weather conditions.
Keratin is divided into two types - American and Brazilian. But, everything depends on the manufacturer and the composition, so it is worth choosing high-quality keratin.
American preparations contain a substance methylene glycol, which is safe for human curls. Such a product is expensive compared to the Brazilian preparation. But it justifies its price, because the American keratin contains an abundance of natural and useful substances, as well as biological additives.
Brazilian products help to provide a durable and long-lasting result. But because of the content of such a component as formaldehyde, it evaporates when in contact with the technique for straightening hair. This affects the mucous membrane of the respiratory tract and everything settles on the lungs.
FELPS brand keratin is Brazilian, but it is one of the few preparations of the South American continent that does NOT contain formaldehyde.
