The method of burning can only be used for simple identification. Whether the hair is mixed with chemical fiber or not, while some black heart traders, real hair mixed with animal hair such as horsetail, or some mixed with the hair recovered from the barber shop and dropped on the ground, can’t be identified through the method of burning
In order to let customers know more about the characteristics of hair quality and purchase high-end hair wigs, we summarized the following methods to identify hair:
Name explanation: the principle of hair is that we trim the hair whip, it must be the hair that has not been dyed or ironed, after removing the hair scales, it can be called hair.
Many people ask why it’s not better to keep the hair scales, because in order to fix the hair roots on the hair net during the process of wig crocheting, they usually lock the hair at the root of the hair net by folding their heads. If there are hair scales, they are very easy to knot. Don’t talk much nonsense.
Penetration test
It can be used to test whether the cutin on the surface of hair is damaged.
What is porosity? Permeability of hair refers to the ability of cuticle to absorb and penetrate moisture and hair products. Everyone has different permeabilities. When the hair is permeable, the permeabilities will increase. If in the sun, there is uneven color, mixed with a lot of color impure flower hair can be judged as landing hair.
What’s the difference between permeable hair and non permeable hair? The cuticle hair scales of non permeable hair adhere to the hair dryness. When exposed to the light, they can reflect the light on average, making the hair look shiny, and this kind of hair is not easy to be damaged when combing. For the hair with permeability, the cuticle hair scales are open, so the hair is uneven. It is the light that penetrates but cannot reflect the light, so the hair looks lack of luster.
Test method: lift a few small clusters of hair, tighten the hair tail, and use your fingers to slide along the hair stem from top to bottom to the hair root. If there is rough feeling, it is permeable. It should be noted that different parts of hair have different permeability, so it is necessary to test the permeability of different parts of hair.
Elasticity test
What is the elasticity of hair? It refers to the ability of the hair to be elongated and straightened, and then return to the original length. Healthy hair can generally be elongated to one third of its original length. When wet, the elasticity of the hair increases. If the cuticle is damaged, the hair is permeable, thus reducing the elasticity of the hair.
Test method: first pick up a hair, hold the two ends of the hair tightly with the index finger and thumb, and then gently stretch it to see how long the hair can be stretched, and whether the length changes when the hair returns to the original length. Usually damaged and inelastic hair can’t stand pulling and is easy to break.
Exclusion of cost accounting
Through the rising cost of real hair principle year by year, plus the management cost, operation cost, and inventory cost, the industry currently produces half hand-woven wigs and all hand-woven wigs with the same hair. If the factory directly sells the 30cm full hand-woven wigs, the price is less than 2000, and the cost calculation can basically exclude the non hair products. Generally, the online direct sale is about 2500-3000, which is in the mall In China, 25% of the exclusive stores are commonly used. If the price of the mall is about 3500-4000.
