I second the suggestion for laser hair removal.
I was getting ingrowns in the bikini area for the last couple of years. I started laser hair removal last summer and started having immediate results. Half of my ingrowns/scars disappeared after the first treatment. The rest disappeared by my third treatment, never to return. I never had to shave my underarms or bikini line ever again after the second treatment - just a tiny bit of extremely fine hair by 3 weeks - couldn't see it unless you were up close. For the brazilian, I had to shave for the first 5 treatments, and then had almost no hair growing.
By the end of 8 treatments, I had at least a 95% reduction in hair. I have a few very fine hairs in the underarm area, and I have done 1 extra treatment so far at a reduced cost. I have no hair growing 5 weeks after my last (8th) bikini/bikini line treatment.
I have to say that "they" did not expect me to get the results that I did for my olive skin (they expect 80 - 95% reduction for white skin, 70 - 85% for olive skin, less for darker). They use an excellent machine for all skin types, which reduces the risk of burning darker skin while allowing them to be less conservative in their settings. I have never burned, but they always use ice packs before and after the treatment, just to make sure. I also have to mention that I was waxing for over 15 years, so I started with lighter hair growth than it once was. Make sure that the place you choose uses state of the art equipment and guarantees results. I have heard that some cheap places use equipment not much stronger than a light bulb - not very effective. The place I chose cost not much more than the cheapest places, but had the quality machines.
Laser is virtually painless, but if you are having NO pain, you will also get little or no results! You and your laser technician have to find the right settings for you - that you can tolerate, but not TOO comfortable. Good luck!
