To time to taste a bit of a different look, I've always wanted curls, but no perm. So an attempt with a curling iron, not at all bad from her result, but constantly burnt fingers and scalp.
So now with the styling brush.
By the bristles the hair remain on the bar and you have not set manually. If they are sufficiently heated, you can just turn the knobs, the bristles are retracted and the hair thus fall loosely - and hopefully curly - from the bar down.
I am completely satisfied and use this device now regularly!
