But, unfortunately, cute curls do not last long, sometimes 2 days at most. The most reliable way to get permanently wavy curls is a chemical wave of hair.
What it is?
Permanent, it's the same perm permitting to wear curvy locks up to several months. It's all about the chemical composition that I process my hair. Without delving into the chemical details, let's just say that the shape of the hair is imparted to sulfur bridges or, in scientific terms, disulfide bonds. Just the bridges, and break down the chemicals with which the hair is processed. This allows the hair to accept absolutely any position that can be determined by the type of hair curlers and the way the hair is wrapped. Then I process the hair with a special fixer, which strengthens the disulfide bonds of the hair in a new position. In the end, when the hair curlers are removed, the hair retains a new shape for it - curly.
The birthday of a perm of hair is on November 16, 1906. Just on this day, the hairdresser K. Nessler in front of the audience held a wave of his own wife's hair. Then for the perm, special brass rollers were used, which were heated to an extremely high temperature, and then the hair was treated with chemical substances.
So what is the perm of hair?
Curl hair can be divided into varieties of chemical composition, which treat hair. Our mothers were easier, to some extent: at their service was a wave using alkaline and acid composition. Now almost every year new curlers and types of chemical preparations are being developed, therefore it is easy to get lost in the variety of types of curls. In this case, the previous methods also do not give up their positions.
Acid hair is still popular and is considered one of the most persistent curlers. On the hair, it lasts up to six months, but it is not harmless to the hair, despite the fact that the curling drugs penetrate the hair without revealing its external scales. Thus, a rather hard curl is obtained. Therefore, acid curl is contraindicated in soft and thin hair, as they stretch at the root, and can not hold the shape, and the acid can make them brittle. In addition, we do not recommend choosing an acid perm for the owners of dry fragile hair of sensitive scalp and.
Alkaline curl less resistant, retains its shape until 3 months. Curls look natural and turn out to be elastic. Unlike an acid wave, here the preparations penetrate into the hair opening their outer scales. This procedure softens the hair, but it is not suitable for most types of hair. If the hair is straight, heavy and stiff, it will be less resistant and will last only a month and a half. Alkaline perm is 10-20 percent cheaper than acidic.
Acid wave with the use of thioglycolic acid is rather fragile, magnificent curls lose volume in a month. Nevertheless, this kind is less harmful to the hair, because during the procedure does not cause such a sharp swelling, as in the first two types. Such a wave can be made even on dyed hair.
Neutral curl combines some features of the first types. As part of the chemical drugs that are used for this type of permanent, there is an allantoin, which has long been known for its emollient qualities. The balanced PH composition of the preparations so gently affects the scalp itself and that is shown absolutely for all types of hair. The hair is elastic and strong; the wave itself is relatively stable.
The amino acid perm is included in the composition of the amino acid preparation, as it can be seen from the name, and proteins. They treat and nourish the hair, which helps to minimize the negative impact of using chemicals. Curls are soft, natural and tender. But such a wave is short-lived, and, thus, is not recommended for long heavy and hard hair, as the curls will develop even faster, straightening under their own weight.
Silk perm or waving with silk proteins, sometimes it is called the "Silk Wave". Preparations with the help of which the hair is curled, thanks to the silk proteins in the composition, they carefully care for the hair and not only will not damage the structure of the hair, but will also improve it. Even clarified hair after such "chemistry" becomes healthier. Due to the fact that the curl preparation does not exert a strong influence on the sulfur bridges of the hair, the curls are soft and last for a couple of months. To allow the wave to last longer, use the "Silk Wave" for a medium-length hair or shorter so that it does not straighten out under its own weight.
Biowave is any perm, which does not contain ammonia, hydrogen peroxide and thioglycolic acid. They are replaced by drugs similar to hair molecules, which connect the sulfur bridges of hair. Curl on the basis of such preparations gives the hair not only luxurious curls, but also gives a completely healthy and natural look. Other types of curls, such as Italian (with the use of bamboo extract) or "Angel's curls", which include a botanical complex, also belong to bio-waving.
Curl with a lipid-protein complex LC2 (Japanese wave) are recommended for problem hair. It is much more resistant than silk, and two-phase lipid-protein complexes regulate the moisture of the hair, maintaining elasticity and shine. Curls of medium hardness are perfect for hair just below the shoulders.
Now you know what kind of hair perm is, but know that when you wig, regardless of the chemical composition, you can use a polyethylene cap with special holes through which a special hook stretches the hair strands. After that, a chemical agent and a method of packing are used. It should be noted that the scalp with this method is maximally protected from the negative effects of the chemical, so this wave will suit even a lady with a problematic scalp. It is for this reason that such a wave is also called "childish".
