Query: Not for thick hair

I own this product. It is definately a disappointment if you have thick hair. It takes forever to dry hair and I have to use thin sections (which takes hours) over and over to get any drying effect even on the highest speed. I use it on my 9 yr olds hair, which is thick also and straight. To get any styling effects on her hair, it has to be almost dry first. I feel it works better on naturally straight and fine hair. This wasnt one of Revlons finest. I can see why its discontinued.
