Perm principle for all the time that it is made practically not changed. As before, to create beautiful curls, changing the structure of the hair. But there was such a kind as biozavivka, the main active component of which is a biological protein cystine, which is similar in structure to a substance that is part of the hair. Such a method of curling hair acts more gentle and lasts less conventional chemistry - about three months.
There are several ways that you can get rid of a perm. Alas, they do not give an absolute guarantee, since a lot depends on the characteristics of the hair from the chemicals that were used in the process of curling.
The first way - to go to the same salon where you did this hairstyle, and request return all "as it was." Hairdressers know by means of what they were doing you a chemistry, so perhaps the problem is easily solved. But it has its "pitfalls": you risk severely harm their hair - they simply can not survive another stress and develop a strong fall.
You can try to rectify the situation at home - in beauty shops selling a variety of different means: special straightening balms, masks and gels. This is likely to be cheaper than a return visit the salon, but it's possible impact on your hair even worse - you can get rid of a wave with hair. The use of various devices such as smoothing the hair iron not give the desired effect.
The most secure way - wait for the hair to the industry, and then trimming a perm.
