To date, in the field of the chemical wave of hair, a grandiose coup has taken place - new high-quality high-performance products and preparations have started to be used. From the previous method of curling, there was only the basic principle, which consists in changing the very structure of the hair.
At the same time, the methods of approach to the actual procedure of the curling procedure have made significant progress, at the moment allowing hair to curl, minimally injuring them. The newest products help to avoid the danger of harm to hair with a perm.
Drugs that affect hair have become softer, such as ammonia, are used in them in minimal amounts, almost no alkaline composition is used, and acids are selected as sparing as possible.
What types of perm exist?
By the method of holding the perm is divided into chemical and temporary. Temporary can be carried out at home, but it does not last very long. Chemical is done by an experienced craftsman in the salon and can hold on for a long time.
Before you start the procedure of chemical wave, you need to know that it can not be done during pregnancy or lactation, if you undergo a course of treatment with hormonal drugs or have recently dyed hair.
Depending on how the perm was made, it is divided into the following categories:
- in a spiral;
- "On the pin";
- radical;
- "twin";
- on papillotkah;
- with the twisting of the second bobbin;
- "On a pigtail";
- "Children's".
During the creation of a chemical wave on the hairpins, the impression of curly light natural wavy ringlets is provided.
If the curl is spiral, then the hair is laid in a spiral, which is twisted by small rings that do not intertwine with each other. This kind of waving can be recommended for those who have long hair.
The method of curling with the twisting of the second bobbin, in which the curls of hair are obtained in different sizes, looks rather trivial. This is due to the method of execution, in which a part of the hair is wound first to one bobbin, and then the second one is twisted.
When curling "on the hairpin" creates an effect of curvy ringlets, which looks very good for those who have hair that is shoulder-length or longer.
Also on the hair of a long length, the "wiggle" wig looks good, when the strands are weaved into tight small braids, twisted at the ends with bobbins.
A chemical radical wave is carried out when it is necessary to luxuriate at the roots, while only that part of the strand that is adjacent to the scalp or if the hair that has been exposed to a chemical wave is grown out and it is necessary to make curls at the roots of the hair is treated.
The type of curl "child" is the most sparing option. At the same time, just as with the dressing, you have to put a polyethylene hat on your head, pull out the strands through it and make a usual perm.
The peculiarity of the "twin" curling technique can be called the effect produced, in which a part of the strands of curl in the form of horizontal curls, and the other part - in the form of vertical curls.
Depending on the method of exposure and the materials used, the wave can be divided into the following types:
- amino acid;
- based on acid;
- on the basis of acid with the use of thioglycolic acid;
- neutral;
- alkaline.
On an acid basis, the curl has the strongest effect, is suitable for all hair and allows a long lasting fixation.
Curl, based on acid with the use of thioglucolic acid has a neutral pH and for this reason less harm to the hair, without causing a strong swelling. However, this method of curling is not suitable for straight and smooth hair, as it is very short-lived.
At an amino acid type of a wave are used preparations which allow to saturate hair and promote their fast restoration.
Alkaline curl acts softer than acid, but its effect lasts an average of about three months and does not suit everyone. However, it allows to achieve the effect of natural natural hair.
Neutral curl acts gently and evenly, suitable for all types of hair.
