Dissapointed.  Barely any boar bristles, mostly nylon. [SEP] When I brush with this I don't feel it going through the layers of my hair. I being able to feel the bristles through my hair if I place my hand on the other side when I brush. This doesn't do that. I do have rather thick hair, so it may not be the case for people with thinner hair.<br /><br />Another reason for my disappointment with this brush is that it is mostly synthetic, nylon bristles. My hair becomes frizzy after using it.<br /><br />There is also a terrible chemical smell. I've actually had this brush for years now. (writing a review super late because my good boar bristle brush broke and I had to use this one again...oh boy, the difference). Even after years of owning this brush and washing it occasionally it still stinks like chemicals.<br /><br />I kept it because I needed a brush for my long haired dogs anyway. I went and bought a genuine boar bristle brush elsewhere.
