Chemistry of hair for women, types of chemistry: wet, large or light to medium hair
As the well-known joke says, in women withwishes about hairdos all is simple: straight hair should be curled, curly - straighten, long cut, and short grow. It is the eternal desire for new beauty horizons that allows girls to look unique. And chemistry for hair, as in the common people called chemical perm, is one of the ways of transformation.
What is the chemistry for the hair?
Depending on the composition that is usedmasters for curling curls, chemistry is divided into several species that affect the hair in different ways and give a different effect. So, what is the chemistry for the hair?
Acid perm. It was made by woman of fashion of 1970-1990-ieslast century. Today the industry has risen to a new level, and now such a wave does not burn the hair, but acts much more gently, but the same reagent is used - glyceryl monothioglycolate (pH 6.9 - 7.2). Modern acidic chemistry makes it possible to create curls of any shape that do not decay and keep the wrapping well. The reagent penetrates deep into the hair and fixes the shape there, partially destroying the core of the hair, but leaving it smooth and shiny outside. Such a haircut should not be made to the owners of weak thin hair, but girls with a rigid structure can easily experiment!
Alkaline perm. This kind of long-term stylingis carried out in different versions: pure to create elastic curls, diluted to simulate a light wave and with the addition of plant extracts to compensate for harm from chemical attack. In all cases, the active ingredient is ammonium thioglycollate (pH 8 to 9.5). Alkaline chemistry is less aggressive and does not damage hair so much, because it does not require a temperature effect to fix the effect. Nevertheless, you should make sure that your master has already dealt with this type of styling, because improperly following the instructions can lead to burns to the scalp and damaged hair. The price of this wave is an order of magnitude lower than other options, but it is not suitable for everyone: it keeps on fine, but can not cope with hard hair.
Neutral perm. This method is for those who want a longeffect, but does not dare to make a full-fledged chemistry, which holds, until you cut it off. A composition with a neutral pH will help curl curls in curls or waves for several months without damaging, and even restoring the structure of the hair due to the keratin contained in it. Gradually the effect will decrease, until after about 4-6 months the hair will not straighten out completely. This is how the radical curl is made for a volume that does not curl, but only lifts the hair on the roots from the head, creating an amazing volume. It is important to understand that after a neutral wave it is necessary to use only special means for hair with neutral pH, otherwise the effect will not last for several weeks.
Bio-perm. This prefix does not just causeusefulness of the procedure, but literally determines the composition. There are no usual alkalis and acids, ammonia or hydrogen peroxide is not found. The active ingredient is cysteine, akin to the natural hair proteins, which, when condensed, fixes the curls in the desired form for 6-9 months. The hair after this procedure is lively and shiny. The main minus - the producers have not found a way to get rid of the unpleasant smell, which is eaten in the hair and for a couple of days the owner of the new hairstyle does not leave. Almost all manufacturers recommend that after the bio-sponge, they do not wash or comb their hair for three days, because after washing off the composition, it still continues to gently impact the hair and reaches its final result only on the third day.
Amino acid perm. Producers argue that the regularthe use of the composition not only does not damage, but will restore thin, dull and brittle hair due to the amino acids and proteins contained in the composition. Such chemistry does not take on heavy and hard hair, because it is designed exclusively for weakened thin curls, and here it is applied only to medium or short hair. Large long curls will spin for several days under their own weight, and short and light will keep the shape for up to two months.
Carving - a new word in the wave. This is a modern long-term styling, which does not damage the hair and lasts up to two months. At the same time the composition is designed so that the hair under its influence acquires strength and additional shine. The main disadvantage of this chemistry is the amount that will have to be left in the salon. On the other hand, all good things have to be paid well, so the price is reasonable.
In addition to the differences of the curl on the principle of the main active substance, there are other signs.

A large wave is the dream of many girls. It is these curls that look as natural as possible, as if the hair is curled by nature. Usually large curlers are used for it, or three large bobbins at once, because the standard ones give too little curls.
At the same time, the hair "jumps", creating a large volume and significantly decreasing in length (see photo).
Light chemistry on medium hair
Even more natural and looks naturallight curl that does not create curls, but only imitates a light natural wave. On long hair it is not done, because such an unobtrusive hairstyle will simply fall apart under the weight of the hair, but on the tresses of medium length the vertical wave looks exquisitely.
Wet chemistry on medium hair: before and after photos
Wet hair requires styling with the help of tools,creating the effect of wet hair. Becoming fashionable at the end of the last century, such women's hairstyles are popular now. Curls after such chemistry are still wet treated with mousse or gel, applying the composition to the tips and distributing to the middle of the length. The roots dry up, creating a volume, and the ends of the hair look as if their owner has fallen on a summer rain.
Perm coiled
In contrast to all aspirations for naturalness,which pursue the previous types of curls, the spiral focuses on artificiality. Elastic if puppet curls in nature can meet except that of individual African peoples. A perfect geometric spiral is very popular, as the reviews say.
