I used this to help detangle the horrible knotted/matted/tangled mess that were my twists after washing them and letting them dry/dread up. Took a long time and I lost 2 bristles but it probably was still the best tool I could use. Looking at the hairs in the brush, I guess/hope I lost mostly shed hair. Iono, the hairs were all long, so either they were mostly shed hair or I'm breaking my hair off near the root now.
