Second, the operating principle of hair root positioning perm: small-scale capacity adjustment of local or whole hair roots to achieve the purpose of increasing hair volume and creating a fluffy feeling.
Third, the type of hair root positioning perm: 1, braiding method: braiding hair roots with three hands, the length is about 2 ~ 3 cm, and perming. 2, knot method: tie a knot at the root of the hair, and then perm. 3. Single curling method: the hair is wound on a curling core with a diameter of 0.4 ~ 0.6 cm from the hair root for perm. 5. Direct connection method: firstly, the hair root is wound with a small winding core for 2-3 times, and then the hair tail is wound on a large winding core, which can produce a big wave effect of fluffy hair root. 6. Indirect connection method: firstly, part of the hair is separated as required, then another part of the hair is wound around a small winding core for 2-3 times, and finally, the hair ends of the two parts of hair are wound together on a large winding core for fixing, and then the hair is permed, which can produce fluffy and big wave effect.
Fourth, the hair root patch technology: For the long hair that has been permed for 3 to 6 months, if it is permed again, the new hair of the hair tail and hair root after perming will have two different curling effects, which will affect the perm quality. The following is the hair root patch technique. Curl down from the end of the hair as needed until it is close to the new hair. Wrap a piece of plastic paper around the core and continue to roll down to the hair root. After all the curls are curled, apply the first dose, so that the first dose can only be absorbed by the hair roots and new hair, and the curled part of the hair tail can not be absorbed by the plastic paper, thus achieving the purpose of protecting the curls and perming the new hair.
