The main types of chemical hair for hair

Before the advent of chemical wave in the early twentieth century, women sought to improve their appearance, forming curls and curls with the help of papillotok. Breakthrough came in 1905, when Nesser invented an apparatus for hairdressing operations of such a plan. It consisted of metal rods, on which the strands of the ladies, treated with a solution of sodium hydroxide , were wound , after which the "curlers" were heated by means of a current. The first experiments on waving were not always successful, because Often accompanied by burns of the skin and completely damaged hair. The first "victim" of this process was the curls of his wife K. Nesseser, on which he checked the work of his device. These days things are different.

Today there are many kinds of chemical waves. Among them, operations in the acid medium are distinguished (stable curls are formed, but the effect on the hair is very strong), alkaline (lasts up to three months, does not injure the curls), shaping the hairdress with neutral solutions (very soft effect, the wave acts optimally on the hair on any Site).

Among the chemical curls apart is an operation performed with the use of acids from the group of thioglycolic. It can be carried out even on dyed hair, tk. Preparations do not give excessive swelling of the strands, which allows to preserve their quality. A good effect is also given by a perm on the basis of amino acids. She is already treating injured curls as she goes along. It should be noted that curling with soft means does not last long and is not suitable for long heavy hair. Curls in this case will intensively "develop" under their own weight hairstyles.

A perm on average hair is chosen taking into account their condition and quality. If they are dry, and the scalp is prone to irritation, it is better not to order acid chemistry. With straight and hard Oriental hair, an alkaline variant is not suitable, because He will last for a month and a half.

How the hairstyle will look after applying chemical curls depends also on the way of winding. This can be processing on the hairpin (give curls that are similar to natural), on a pigtail (you will get a wavy "mane"), on the hairpin (curls will look like curving snakes, suitable for short and medium lengths). Twisting from the category "twin" can give an interesting effect, because Part of the length is wound horizontally, and a part - vertically. For short, weak hair, chemistry can be made at the roots to increase the volume of the hairstyle.

A large perm, the photo of which is presented in the article, can be obtained using special curlers (Olivia Garden), which in combination with special preparations give a hard curl (for medium length hair). It is also possible to model the appearance with the use of vellaformers, which are latex bags, in which curls curl by the compression (low stamina, the hair at the root remains straight).
