Art brushes keep fraying

[Dazzlingnails]

Hey! So I bought lots of new brushes and keep running into the same problem. They after only a little while keep fraying so it makes art difficult. They are not cheap brushes either so I would like to find a way to fix them. Any tips on how to make them new again and how to avoid that from happening?

How are you cleaning them?

I use the brush cleaner that comes from the same company.
