Permanent waving (or just "chemistry") of hair does not lose its popularity, and with time it undergoes some changes, which makes it even more perfect. The basis of such a wave of hair is a chemical reaction aimed at modifying the so-called sulfur bridges, which play a major role in the formation of hair curls. During the reaction, some sulfur bridges are destroyed, others are created anew, so that the hair becomes curly or wavy. Over time, the sulfur bridges oxidize with oxygen in the air and the hair begins to straighten.
Do not be afraid that a permanent wave will spoil the hair and lead to their loss. Experts argue that the chemical compounds used in hairdressing do not penetrate the hair follicle or scalp and do not destroy normal hair growth. Modern chemistry does not cause serious harm to the hair, only a little discoloration.
Popular types of permanent wave

Especially suitable for those women who will wear "chemistry" as an independent hairstyle. The American haircut is made on special curlers Olivia Garden, after which there are no creases on the hair, and the order of the curls corresponds to the location of the future hairstyle.

Curling on velvetformers - is carried out with the help of special devices created by Wella. According to the technology, hair is not wound on curlers, but they themselves are curved from the inside. Strands are placed in special narrow latex bags, after stretching them. Then they are compressed, while the hair is folded into rings. As a result, soft waves with a "broken hair effect" are formed, which are easy to use as a base for laying. This wave lasts 1,5-2 months. Velloformery designed for hair length of 20-45 cm, the roots of the strands remain straight.
