Give it the brush off
I don't know exactly what "white bristle" means but I think it is not animal derived. That is Ok times being as they are at present.
To the point: This brush feels Soooooooo nice on my scalp. You know it seems to awaken my scalp in some way or another. The first few combs made my hair kind of "finer" in some way and it lay flat. Not so good, I thought. By the third or fourth brush the hair had a loft and shininess that no ludicrous -priced conditioner or hair product had attained.
Try it more than one time. Don't overwork the brush. Let it glide, and leave it alone.
My hair is medium fine and is not oily or dry--just in the middle. My hair does tends to get mucked up with conditioner and over-formulated shampoo. Argan Oil is too much for me and I tend to use just a tiny bit of conditioner and it works good. A good Kent brush will remove the build up on the hair shaft. If you use a fine shampoo you may not need as much conditioner down the road. A good brush restores the texture and luster of your hair.
This brush gets down to business..So gentle. You know, it seems to sooth me this brush. Maybe too much coffee. Yep
