Why does the brush head get dry or clump?

This is likely because the bottle wasn’t tightly closed, or the brush head was exposed to air for too long. Before using, we recommend shaking the nail polish bottle. If you notice small dry clumps on the brush, you can gently wipe them off with a cotton pad dipped in nail polish remover. If the entire bottle has dried out, it’s best to replace it with a new one. Always make sure to tighten the cap immediately after use to prevent air from getting inside.
