Hello, I understand your concern to for best way for hair removal from vagina and hands. It is really bothersome to have unwanted hair especially in females and to maintain a good hygiene. In cases of coarse hair in vaginal or hand areas I prefer to do Laser hair reduction procedure. It is one of the supreme methods for making the hair fine and thin. There are various different types of lasers are offered. In my patients I generally prefer laser for hair reduction ranging from Intense pulse light to NdYAG laser. A proper dermatologist can best decide a laser according to your skin type and hair type. This is one of the lasting methods so would give best results. You can discuss these points with hair treating laser dermatologist. For getting color back you need to meet a dermatologist and then can take various treatment option including medical treatment as well as chemical peelings or related procedures. All the best.
