When i use nair, my skin breaks out into itchy red bumps and my skin burns. idk if that means i'm allergic to it. but it burns terribly when i use it under my arms and my legs but fine on my stomach. anyway, i just use a regular razor for shaving my legs and underarms but it never shaves completely and i don't want to make waxing an option. also, what should i do about my private area? what should i use?
