Not recommended for thick hair.
I have very thick long hair that fell out due to illness so I had it cut short. I was somewhat skeptical of how well a heated brush would work on my thin hair, having never had any experience with products for thin hair. It worked fine when my hair was extremely thin. This work pretty good to touch up the top layer of my hair, but is too bulky and does not get hot enough for the new thick undergrowth that is very cowlicky.  In all fairness, neither my straightener or curling iron work on it either. It would never have worked on my old hair. I would recommend for women with thin to medium hair who need a touch up after regular styling.
