Going to salons for hair removal

I struggle with hair removal in my private areas. I have tried to keep my razor clean, often disinfecting it, but I struggle with thrush, pimples which contain pus and intense burning and itching to such an extent that I can't walk properly. I have very sensitive skin so that affected me greatly. When I was in ihraam for umrah, it even affected me then. The pimples left scarring which also left me embarrassed in front of my husband. I have gone for a full bikini wax at a salon and it helped me tremendously and I am comfortable to go about my day. However. I have heard that it is haraam to get a bikini wax if someone else does it for you. I have tried to do it to myself, but I caused a lot of harm and pain when I tried. Please help me as I don't know what my options are anymore. I would like to continue to go for the waxing, but now that I hear that it's haraam for someone else to do, I'm very scared to do so. Please assist me.
