Why the makeup brushes fall hairs

Many ladies are troubled by the hair falling of makeup brushes no matter how expensive the brushes are. If the brushes keep falling many hairs for long time, it must be quality problem. But most makeup brush manufacturers will tell you that it is normal to have several hairs falling at the beginning. Here we would like to explain why the makeup brushes fall hairs:
It is known that the standard production process should be as following: weight certain hairs and comb, insert the hairs into moulds to shape, bundle up the hairs with string, insert the hairs into ferrule and adjust the exposed length, dip glue onto the hairs from ferrule, shape after glue dried, assemble handles, and pack the brushes for shipment.
The whole production process is manual, so the work craft will determine the quantity of hair falling.
Firstly, if the hair quality is not good, with too many short hairs or broken hairs, the brushes will certainly fall a lot of hairs.
Although the combing can remove some short hairs, it can not remove all short and broken hairs. That is why it is normal to have several hairs falling at the beginning.
Secondly, during bundling up the hairs with string, as good animal hairs are very soft and thin, if too tight, the hairs will be broken; if too loose, it will affect the glue affect. Therefore, too tight or too loose will both cause hair falling. Also, to save time and cost, some low-grade makeup brushes will cancel such process, which will certainly cause hairs falling.
Finally, gluing is one of the most important processes for hair falling. The glue should be a kind of special glue, with waterproof and can withstand high temperature. Otherwise, the glue will dissolve after watering, and then the makeup brushes will fall buckets of hairs. Also, during washing brushes, if the glue can not sustain high temperature, the makeup brushes will also fall a lot of hairs if the water is a little hot.
Anyway, it is normal to have several hairs falling at the beginning. Users no need to become angry once seeing hairs falling and assume it to be quality problem. In the following articles, we will introduce some methods to reduce hairs falling of makeup brushes during daily using and washing.
