It doesn’t exist yet. I want to make one because I haven’t found what I consider the perfect round brush. I have found one that comes close.
The Wet Brush Epic.
It will do in a pinch. It does not have the raised edges which could catch and pull hair out. It has the metal barrel for heating and shaping the hair like a curling iron would.
It has nylon and boar bristles. Nylon to detangle, and boar bristle to defrizz and add shine.
The only “downside” is the handle doesn’t have a soft cushioned grip. After applying slippery product to my damp hair, my hands are to slick for a good grip.
Like I said. Almost perfect.
Give this brush (link to purchase below) a try and let me know what you think!
