The answer to both of your questions is yes. Waxing will help, it does however get expensive and you are still susceptible to razor bumps and ingrown hairs. That being said I can recommend a product that works miracles Skin Rx Clinic carries a product called PFB Vanish. It is specifically formulated to heal and prevent ingrown hairs, waxing/razor bumps & razor burn. It is a soothing gel that immediately calms redness and irritation. Also, and I know you don't want to hear this but... Shave "with" the growth of the hair...not "against" it! I know everyone thinks you get a "closer" shave when you shave against the hair (and you do) but you are also setting yourself up for unattractive, sore, irritated skin with razor bumps and ingrown hairs! And let’s be honest, even when you shave against the hair there is already stubble the very next day...only to be accompanied by razor bumps, ingrown hairs and irritation! So just to recap...shaving "with" not "against" the hair shaft will drastically reduce the possibility of ingrown hairs and razor bumps, and PFB Vanish will immediately heal and prevent existing and new bumps from emerging. You can get the PFB Vanish at www.SkinRxClinic.com search "vanish" and the product and description will come up.
