I'll do the nair before going to the pool or beach, or if I want to show off mowing the lawn without a shirt. Otherwise I'm a gorilla. A trimer for everything else about once a month through the summer and naired back and shoulders keeps me happy. Note: the women's stuff is MUCH stronger than the men's. I guess they know women are going to follow direction and men are going to go the max time no matter what. So the nair for men actually takes 10 to 15 minutes. But when the women's bottle says check in 3, you better check in 3. I couldn't find the men's stuff at Walmart so just got the women's stuff. I left it everywhere for 10 minutes. It burnt my shoulders and took the skin off my balls *(I do those too for the wife). Man what pain. But the women's stuff works better if you cover qickly and start checking by wiping with a piece of toilet paper. When the hairs come off (3-4 min), get your ass in the shower and start scrubbing. You'll come out smooth with virtually no irritation.
The laser surgery says it takes 3 consecutive treatments over several months.
