You should check out Dr. Arielle Kauvar: http://www.nylaserskincare.com/about-nylsc/1-meet-dr-kauvar/ She's amazing. I've tried a number of laser hair removal places and she is the best I have come accross.I don't know about the red hair situation, but you might as well call in for a consultaion. Pale skin is a must, they will not perform laser hair removal if you have a tan. Paler the skin the better the results. In my experience they have been very overt in terms of what areas will provide results and what areas are not worth the expendiures. However, in general one to two sessions will not do the trick. Generlaly 4-6 sessions depending on the area as some areas are more stubborn than others. I would ask them about the intensity of hte laser becuause there are different settings and perhaps you will be able to do fewer sessions with the results you want if you can use a higher laser setting, but defnitley ask about this because i am not totally sure. Also, you may experince ingrown hairs, whic can be avoided if you regularly keep up with visits for treatments every 4-6 weeks. If you are short on cash and need to spread the treatments out over timet ask for a prescription of Clindamycin Phosphate topical lotion, which prevents ingrown hairs, which are caused by the weakend hairs that make it more difficult to come through. Another alternative is Dangene who works at the core club. I haven't used her for electrolysis, but I do see her for dermatology and she is great. It's pricy, but the results have been worth it for me. Hope this helps.
