I already own a paddle brush with nylon and soft tips, but I was wondering if a large with long boar bristles and a bit of nylon bristles paddle brush is a better bet when it comes to brushing hair in the long run?  I already have a narrow boar bristles brush but it's too small for my thick hair. I was curious if I should get boar bristle paddle brush I just described in addition to my nylon paddle brush or it's not necessary? I heard that it will aid with distributing the scalp oils and make hair shiny and healthy.

Brushes on long hair are typcially used to distribute oil or put a smooth finish to your hair.  In the case of the latter, the brush would not necessarily penetrate all of your hair.

Thanks, ladies! I guess I wouldn't waste my money spending on the boar bristles paddle brush then. I already own my favorite tortoiseshell wide tooth comb I've been using for years and worked well for me.
