When we have to buy wig sets for various reasons, the first consideration is the material of wig sets. How to select high-quality wig sets? Don't worry, let's introduce it slowly:
To identify whether the material of the wig is good or not, the method of fire can only simply identify whether the hair is mixed with chemical fiber, while some black heart traders, the real hair is mixed with animal hair such as horsetail, or some are mixed with the hair recovered from the barber shop, which can not be identified by the method of fire.
Here are the methods to identify SHUNFA:
Explanation of Name: the principle of smooth hair is that our trimmed hair whip must be uncolored and unpolished hair. It is called smooth hair after removing the hair scales.
Many people ask why it is not better to keep the hair scales, because in order to fix the hair root on the hair net, the hair is usually locked at the root of the hair net after folding the head. If there are hair scales, it is very easy to knot the discounted hair.
1、 Porosity test
It can test whether the hair surface, that is, the cutin of the hair, is damaged.
1. What is porosity? The permeability of hair refers to the ability of hair cuticle to absorb and penetrate moisture and hairdressing products. Everyone has different hair permeability. When the hair has permeability, the permeability will be enhanced. If the color is uneven and mixed with a lot of flower hair with impure color under the sun, it can basically be judged as landing hair.
2. What is the difference between permeable hair and non permeable hair? The cuticle hair scales of non permeable hair are flat against the hair stem. When exposed to light, they can reflect light evenly, making the hair look shiny, and this kind of hair is not easy to be damaged when combing. For permeable hair, because the cuticle hair scales are open, the hair is uneven. The light penetrates and cannot reflect the light. As a result, the hair looks lack of luster.
3. Test method: lift several small clusters of hair, tighten the hair tail, and slide your fingers along the hair stem from top to bottom to the hair root. If there is a rough feeling, it has permeability. It should be noted that different parts of hair have different porosity, so it is necessary to test the porosity for different parts of hair.
2、 Elasticity test
1. What is the elasticity of hair? It refers to the ability of hair to be elongated and straightened, and then return to its original length. Healthy hair can generally be elongated to one-third of its original length. When wet, the elasticity of hair will increase. If the cuticle is damaged, the hair has permeability, which reduces the elasticity of the hair.
2. Test method: first pick up a hair, hold both ends of the hair with your index finger and thumb, and then stretch it gently to see how long the hair can be stretched, and whether the length changes when the hair returns to its original length. Usually damaged, inelastic hair can't stand pulling and is easy to break
3、 Cost accounting exclusion method
Through the rising cost of real hair principle year by year, plus the management cost, operation cost and inventory cost, the industry currently uses smooth hair to make semi hand woven wigs and full hand woven wigs. If the factory sells directly and the price of 30cm full hand woven wigs is lower than 2000, it can basically exclude non smooth hair products from the cost calculation. Generally, online direct sales are about 2500-3000, In the exclusive stores of the mall, the domestic general price is 25%. If the price of the mall is about 3500-4000.
