My MAC blush brush, while beautifully shaped, is old and washing has made the hairs quite rough (I’m pretty sure it goes back years when beauty magazines would tell you to wash them with baby shampoo. ) I’m a little disappointed to get rid of TBH. Now there are about 50 different blush brushes and I don’t know what to get just to put some blush on my face. Dish? Round? Synthetic? Natural hair? I have quite a few eye brushes and other face brushes, like foundation and highlighter, but only one blush brush. Recommendations? And / or some way to smooth out the bristles and save my current brush, at least as a backup? Thank you!
