Review title is great.. [SEP] I thought, one piece, great... I was wrong. First, this feels terrible on my scalp. That may just be me. I tested it to see how it would work after I had already brushed my hair with my normal brush but instead it tore out my hair. I have no idea how that happened but it did it with both brushes. I then decided to try it with a few tangles in my hair and it wouldn't pull through... I would not recommend these...
