Needless to say as soon as I got home I ordered myself 2 from ASOS.com.
These brushes look like the old fashioned ones that grandpa's used to use, that were round. And the bristles are really fine. I'm not sure what it is about the structure, but it just works really well on both wet and dry hair to get all your tangles out.
You can buy the large for $17 and the travel size for $20 on ASOS.com
