I used to have horrrrrrible knots in my hair when I was younger. Even in my early teenage years, mom would take looong times (hours, even) to get all the knots out for me.
Now? I'm one of those people that you said there aren't any of. I totally haven't had ANY knots in my hair in probably....two years. The conditioners I use almost exclusively are GVP Conditioning Balm, Giovanni Direct Leave-In, and Kinky Curly Knot Today. I use Suave Coconut for my co-wash (I've never been able to decide...is Suave Coconut an ok condish?)
Anyway, I'm not sure if it's just me being lucky, or if it's the products I use, or what, but...I literally never ever have knots in my hair.
