How to perm healthy hair and how to master the time and steps of perm (free study)

In hair salons, there are so-called digital perms, ceramic perms, thermal wave perms and so on. The principle is the same. In addition to softening hair with chemicals, we also need to change its molecular structure with heat energy to achieve the design goal of hair stylists. Therefore, in the process of operation, we should pay attention to the following points in order to achieve elastic wave: 1, and we should judge the hair quality before perm. Different hair softening time is different, and the products to be used together. Observe the softening degree of hair at any time, and don't let the hair be excessively damaged. If the hair is excessively damaged, it is difficult to perm a very elastic wave. 2, do a good perm must understand the characteristics of the products used. Each product has its own characteristics, which requires us to know its performance before using it, and then use our own judgment on hair quality to grasp the time. Otherwise, even if we give you the top grade, it will be counterproductive. 3. Pay attention to the selection of lever and the diameter of lever. Be sure to choose a barbell with uniform temperature, because the heating temperature of barbells produced by different manufacturers is sometimes different, and some old barbells have different heating temperatures than new barbells, so it is necessary to check the heat of barbells in advance to ensure the consistency of fluctuation elasticity. As for the size of the barbell, it is determined by the design. 4. The key to blanching is to control the temperature. As mentioned above, the time and frequency of heating should be controlled by the combination of hair and product. The temperature of damaged hair should not be too high, and it can be heated in several sections, and each time should not be too long; The temperature of healthy hair can be slightly higher, the frequency can be smaller, and the time can be longer at a time. This should also be done in combination with the product description. In short, you can't let your hair perm, whether it's chemical or physical. 5, blanching should pay attention to the strength of the bar. There should be some strength on the bar. It's very important to make the hair stick evenly on the hair shaft, and it can't be elastic, because it depends on it when styling. If the hair is loosely wound on the barbell, the waves will have no power, and vice versa. 6. Bleaching requires sufficient setting water. It is also important to replenish styling water. It is necessary to fully penetrate every hair, especially the end of the hair that is rolled inside. If the hair ends are not completely shaped, it is impossible to perm an elastic wavy hairstyle. Long hair needs to be added twice The first pass is enough to remove the barbell and then add styling water to the end of the hair. Wait five minutes before flushing. In addition, I suggest not to change the barbell and add styling water, because it is difficult for the hair to stick to the barbell after changing the bar, but pay attention to blow-dry the two-pole contact of the barbell after use, otherwise it will be easy to short circuit. The above points are the essentials to be mastered in blanching, and I hope to give you some inspiration. As for half damaged hair and half healthy hair, it is necessary to soften the healthy hair first, and then gently soften the damaged hair after the healthy softening is completed. Then, when you curl your hair, you can apply some hair care products such as amino acids to form a protective film on the damaged hair. It is best to use an external heater when heating. If the temperature is damaged, press point 4 above. Related hairdressing study courses:
