Hello, I understand your concern to for pubic hair and to make these hairs smooth and thin. In all cases of coarse hair at pubic and axillary or any other areas I prefer to do Laser hair reduction procedure. It is one of the finest methods for making the hair soft and thin. In case of pubic hair too I suggest my patients to go for this procedure. There are various different types of lasers available for hair reduction ranging form Intense pulse light to NdYAG laser. The best laser can be decided according to your skin type and hair type. This is one of the permanent methods so would give long lasting results. You can discus these points with hair treating laser dermatologist. It is one of the simplest methods and is good to maintain a better hygiene thereby preventing any infection. I will be glad to guide you any further. All the best.
