Laser Hair Removal... Failure

So, I went all the way to Gangnam to go see a doctor on Tuesday morning to see about getting laser hair removal. I was seen right away by the doctor, who specializes in English speaking clients. His English was very proficient. He gave me a little introduction to what Laser Hair Removal is all about and explained to me that hair to be removed needs to be dark and coarse. Then he told me that my hair is not dark or thick and the results would be 50% at most if he did the procedure. Not to mention he would have to set the laser to stronger settings and need more treatments, for lower results.

I'm very happy that he was honest with me. He could have told me anything and I would have believed it and gone through with the procedure. My only complaint is that he didn't look at the actual hair that I wanted to remove. I assume that he was looking at the hair on my head, which is a fine texture, and may look light when the light hits it (like through the light from his window), but it is definitely brown hair. The hair that I want to remove feels very coarse to me, though I'm no doctor. Maybe there's something doctors can tell by seeing the hair on your head to tell about the rest of your hair? Another idea I had was that his equipment was mainly for Korean hair which is obviously very dark and so my medium brown hair would be too light for the equipment in his office. I had two friends who went to this clinic and were very happy. They both had brown hair, but maybe a shade or two darker than mine...

Anyway, now I'm stumped whether or not to get a second opinion. I don't want a doctor to tell me it's going to work when it's not going to work. At the same time, I'd be happier if a doctor looked at the hair I want to remove before making further judgment...

Any suggestions?
