Friendly brush.
However, be careful if you have knots in your hair or if you have frizzy type hair, it will be difficult for you. Personally, having curly hair, I had trouble at the beginning for the tangles, I had to do it sometimes using my fingers, I would say that this brush would be more suitable for people with straight, curly or curly hair with curls that are not "too tight".
On the other hand, once the knots have been untangled, the brush is really effective, it does not hurt the scalp and is as effective as a boar bristle brush (plates the hair very well)
