The boar hair bristled hair brush was another brush that I used for many years. I purchased several different boar hair bristles of different consistencies, shapes, and bristle qualities. I've owned all that are pictured above and then some. My favorite was the "boar hair paddle," a rectangular shaped brush with a long handle (pictured on the left). That brush and I went way back... lots of good times shared. I only purchased brushes with 100% natural boar hair. I knew that some boar hair brushes were being advertised as such yet the bristles were a mix of synthetic hairs, not necessarily natural boar hair. Those brushes will tear your hair up if you're not careful!
I would use this brush sometimes daily on my wet natural hair. The frequency of my use of the boar hair brush definitely took its toll on my hair. I lessened my usage to my hairline only until I stopped using the brush completely. I used the boar hair brush primarily to smooth back my hair with gel or a moisturizing product. I absolutely loved how smooth my hair would look and feel with this brush. My "waves" were poppin' fabulously. I used this brush on both wet and dry hair. Then, one day I began to notice mid-strand split ends throughout my hair. My overuse of this brush resulted in the stripping of my hair strands, causing a split in the middle of the actual hair follicle. This was the worst hair condition I have ever had to face! I also noticed that my hair texture had a much more 'rough' feeling to it at the top of my head compared to the back near the nape of my neck--this was because I frequently brushed the top of my head. My natural hair no longer had that smooth, soft touch that it once had :-/
This is my experience with how I've used the boar brush on my fine, coily hair. Every natural head of hair is different from the next so my experience may differ from yours. This brush can be found practically in any beauty store or online. If you want super slicked down hair, then this brush will achieve that look for you. You just have to be mindful of the frequency of your brush strokes and of how much tension your hair can tolerate.
