The bristles are deformed, is there any simple maintenance method?

It is normal for the bristles to deform after long-term use, but regular maintenance can extend the life of the brush head! Here are some tips for you
Be sure to wipe the nail polish on the brush head clean after use to avoid residual hardening that causes the bristles to stick together.
Don't bend the bristles hard, apply the nail polish gently to avoid pulling and deforming.
When storing, place the brush flat or upright to avoid squeezing the bristles.
If the bristles begin to deform, rinse them gently with warm water, then pat them dry with a paper towel, and the shape will be better after drying.
It is best not to place the brush head in a high temperature or direct sunlight to prevent the bristles from hardening.
If the bristles have been severely deformed and affect use, it is recommended to replace the new brush head so that the coloring is even and beautiful~
