YAG laser hair removal worked better on lower setting?

Is it possible that this could be the case? I am a 20 year old female of indian descent and I have excessive hair on my face. I have had 5 treatments of yag laser hair removal on my face and so far I can only see the hair thinning. In the first two treatments on the lower settings i saw the most difference, hair was actually dropping out, whereas on the higher settings, no difference was seen. Is it possible that i respond to lower settings better? Should I tell the lady to lower the setting?
