My Synthetic brush has curled at the tip. What can I do?

It is important to know before we discuss this further that synthetic fibres wear out and natural hair brushes wear down. The reason for curling at the ends of the brush can be down to several factors:

1. The surface you are painting on.
2. The surface that you are mixing your paint on.
3. Your technique. e.g if you ‘scrub’ with your brushes, this will wear them out. This causes friction and thus the hairs to splay/curl.

You could try the ‘boiling water’ trick. Carefully pour boiling water into a suitable container, immerse the brush head for 30 seconds to a minute then reshape and allow to dry naturally. This sometimes revives the twist or curl in the brush head.
