I'm going to be honest I didn't even know Tangle Teezer did a brush specifically for thick and curly hair but boy am I glad I do now. My hair is extremely thick, coarse wavy and just generally a bit of a tangly mess. I do love the original however I do find it doesn't quite get through all my hair and I have to separate it out into sections which is all round just a bit of a pain. With the specially designed one I find it gets through all of my hair no bother and doesn't leave my hair looking too frizzy and crazy.
I do tend to prefer to brush my hair when it's wet and I find this performs for me much better than the original. I feel like the bristles on the Thick and curly brush are sturdier therefore they make much easier work of knots in thick hair. However they aren't to sturdy that they make it difficult to brush with. As with the original Tangle teezer I really love the super compact design as it makes it perfect for traveling with or throwing in my bag.
Overall I'm really impressed by this brush and would highly recommend it to anyone with, curly, thick or coarse hair.
