2. The thickness of the hair piece should be greater than the radius of the rod and less than the diameter of the rod;
3, the partition should be symmetrical, the thickness of the hair piece should be uniform, and it should not be squeezed or pressed;
4, the tension is important, and it must be even from left to right, and the hair tip cannot be broken;
Hairdressing standard bar is an essential tool in the process of perm. Different types of sticks, using different curling techniques and perming drugs, can make different styles of curly hair. It is a basic tool that hairdressers must skillfully use. There are ten models of label issuing strips, and the length is about 8 cm (different manufacturers have different processes, which will be slightly different).

Matters needing attention in hairdressing standard column:
1, accurately judge hair quality;
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. Understand the performance of the products used;
Each product has its own characteristics, so you need to know its performance before using it, and then use your own judgment on hair quality to master the time. Otherwise, even if it is used in top products, it will be counterproductive.
3. Choose the right barbell;
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.
4. Temperature control;
The combination of hair quality and products can control the heating time and times. 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.
5, 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. Condensed water should be sufficient;
1) adding styling water is also very important. 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.
2) Long hair needs to be added twice. The first pass is enough to remove the barbell and then add a 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.
