This is a fine brush for very fine hair; perfect for a baby brush. I'm not a baby. ;)
I have long hair and this brush works okay for the top layer, but the bristles aren't strong enough go right through to remove tangles. I use my old plastic (yuck) bristled brush in the morning & this one works for neatening at other times.
(I'm a vegan and don't want to use animal products, so no boar bristled brush for me.)
