What are the reasons for brush shedding

Many new customers have come to inquire about the issue of hair loss when using a newly purchased brush?
1. The brush needs to be perforated for hair planting, and the diameter of the hole varies depending on the customer's use, with holes ranging from 1.5 to 10 mm. Firstly, there are several important factors that directly lead to hair loss when the master adjusts the machine.
Each hair bundle and eye hole must be full, otherwise hair will fall off, which is one of the reasons.
2. In addition, when the hole is full, the pulling force of each hair bundle is not enough, and the normal bristling force in the brush industry is 8 kilograms.
