I have long, thick, curly hair and it's usually a nightmare to detangle. I use this tangle teezer when I'm washing my hair, while the conditioner is in and don't have to do anything else once I've come out but apply some product! No knots, no frizz. My dad bought one for his five year old who has Afro-carribbean hair and he's found it a lot easier styling her hair too. A few of my friends have also tried it out and noticed the difference just when brushing their dry hair. It really is a great little tool. I've had mine for three years now and I'm sure it'll last many more years to come.
