Thank you so much for the video! I bought a brand new makeup brush set (online)- one for myself and one for my friend, and one of the brushes have this same problem. The bristles got split in the traveling case it came in. And the split actually runs down to the shaft of the brush. I am going to try this technique to help restore its original shape.
Thank you so much for the help! Been trying to figure how to fix my brushes since the bristles was bending so much to one side, it was getting harder to work with the brushes. ^U^
in case someone gonna read this again, just dip it in the water for a few minutes and it will soften. if you're not sure/afraid if it will bend, just try stroking the brush lightly on your palm back and forth.
i seriously need new, not chinese brushes. This literally promises acrylic, oil, and watercolors yet it cant even handle watercolors! Smhh Sadly it doesnt look like its working but hoping for the best! my younger cousin keeps ruining my brushes oof
