Translated from Latin, the word "permanent" means "permanent". Based on the name, it can be understood that the result of straightening will be permanent. This is due to the presence of chemicals that break down the disulfide bonds inside the hair shaft. The reaction takes place with natural keratin, which is the main constituent of the hair.
The compositions used in the process of chemical straightening have the most gentle effect on the curls, and the natural ingredients provide the strands with shine, smoothness and a well-groomed appearance, reminiscent of the result after salon styling. Since the procedure provides a long-lasting effect, in the course of natural hair regrowth it will be necessary to correct the root zone., especially if the work was carried out with naturally curly strands. Chemistry of the latest generation does not deform protein compounds in hairs, but only acts on disulfide bridges. And the destruction of cystine and its derivatives is compensated for by protein complexes of a different type, which provide elasticity to the curls.
