Is Lightsheer Diode Laser the Best Option for Chin Hair Removal?

I have never had any kind of laser treatment before, and I have an appointment scheduled this afternoon for lightsheer diode laser hair removal. When I booked it, she told me to shave the area first. My concern is that I wanted to have my chin done, but I only have 5-10 dark hairs that bother me, the rest of the hair is so fine and blone that it is "invisible". I'm nervous that if I shave my chin for treatment that these hairs will become coarser or stubbly, especially after reading that this type of treatment doesn't work well on light/colorless hair. I've been plucking the few dark ones out for a few years because there are so few, but I've been getting ingrown hairs and more self conscious since I don't always notice they are back since some are in hard for me to see places. In addition, my face is breaking out since I'm always touching it to see if I feel any of the hairs coming back. I was hoping for a more permenant solution, but now I'm not sure if this treatment is the most appropriate. I plan to have my underarms done anyway, but should I hold off on the chin and try something like electrolisis instead? I'm open to any other suggestions anyone has!!
