Review (5/5): I'd recommend googling some info about them before buying
If you've never used a boar bristle brush before (or any natural type of natural bristle, I suspect), I'd recommend googling some info about them before buying. You don't use them quite the same way you'd use a brush with hard plastic bristles. You definitely want to comb the tangles out of your hair first, for example, and wait until your hair is dry to brush it. (Maybe you're supposed to do those things anyway, for all I know -- I have shorter hair so it's easier for me to use brushes incorrectly without too much damage, but I find plastic brushes more forgiving.)
Because of those things, I'm not sure a boar bristle brush would be great for styling my hair -- but I didn't buy it for that anyway. I bought it more as a type of hair treatment, to get the benefits of boar bristle brushing: distributing oils evenly, improving the condition of the hair, stimulating the scalp, extending time between washes, etc. I have oily hair, but all that oil just build up on my scalp. With this brush, my hair feels and looks much more balanced. I do get some static while brushing, but it settles down quickly.
The brush itself is durable, seems high quality, and has a ton of nice stiff bristles. It feels great on my scalp, and I love being able to help my hair's health without having to slather on a ton of extra treatment products!
