The blue denotes places which should be shaved on the male body.
This doesn't mean you need to be hairless there, but you should get it under control. Hair looks fine and good on certain areas, namely the head, lower face (if you can actually grow a beard), forearms and shins, but on many other areas it looks gross and unhygienic. Who likes back hair or shoulder hair? Nobody, that's who.
I really hate my back hair, thinking in waxing it but it seems like a hassle to periodically go to the place and laser is expensive. Tried with razors but it leaves these little black hair dots and looks like shit, is there a product or way to shave it in my home and look clean?
