What is perm

A chemical wave is supposed to be such a process, when luxurious curls are formed, which retain a certain shape for several weeks and even months. Simply put, those chemicals that are contained in curling preparations, tear apart microscopic internal bonds in the structure of the hair. Therefore, the curls take the form of the curlers used. Then the hair is smeared with a retainer, which holds these bonds together with the wound curlers.

It should be remembered that perm is a dangerous procedure for weakened hair. And only a specialist is able to draw a conclusion: whether to carry out chemical perm or not. To make sure that the version with a curl is suitable for you, try to make the appropriate styling. Look at yourself in the mirror or on the picture like Selfie.

And in the case of straight and stiff hair this term will decrease to one and a half months.

Alkaline curl, unlike the acid wave, will cause the appearance of external flakes on the hair. The composition of the drug includes allantoin. Thus, the procedure can be carried out on different types of hair. As a result, elastic and strong curls are obtained. In preparations of an amino acid perm, proteins or amino acids are contained. They have a curative and nutritional effect on the hair, so the harmful effect on hair is minimal.
