I actually want to put my two cents in on this issue. I have read here time and time again that laser only works on coarse hair and I believed it. Now I’m not so sure. I bought a series of laser treatments on my legs, underarms and bikini. I wanted to do my lower back and “happy trail” from below the belly button to my pubic area but I was worried that the hair isn’t coarse or dense enough. My laser place threw those areas in for free. My laser tech says laser can work on finer dark hair and in factg she lasered her arms and although I never saw her hair to begin with they are smooth and appear hair free now.
Anyway, my back isn’t taking too well to the laser treatments although it is making a slight difference. The hair there is fine, long, dense and dark. However, the area under my belly button has responded surprisingly well. The hair there became slightly coarse from waxing, not too dense, but very dark. It has made a huge difference in the hair and in fact, now the hair surrounding that area looks problematic in comparison! I think it’s a crap shoot so if you are willing to gamble on whether it will work or not and you are prepared to lose your money on treatments that may not work, go for it. Just make sure the settings are as high as you can safely tolerate.
