Query: Not impressed with first try

I've only used this once and was not impressed. I used it on my legs and have course thick hair. It did not remove all of the hair, in fact perhaps only about 30% of it over an extended amt of time...25min. Perhaps, I need to use a larger quantity of it, but then this bottle will be done in about 4 applications.
