I wax my eyebrows...lasts good for like a month before stubble starts to show up again to where it can be waxed again. I wouldn't dare wax my face...although, I'm contemplating it just to see how it affects the growth, and see how much it hurts, lol.
As far as shaving goes, my hair doesn't grow fast, I can literally shave one morning and wait two days before I get a scruffy 5'oclock shadow. I've tried it all, from $200 electric self cleaning Titanium razors to disposeables. Nothing beats a Mach 3....nothing.
The best razor out there bar none is the Gillette Mach 3 (sans a straight razor). I've used that quattro, and Fusion with ALL SORTS of gels, creams and powders. Anything more than 3 razors makes it hard for the hairs to get past the blade edge and rinse out, as well as let more hair get cut. Shave your pubes and you'll get an idea MUCH more than you bargained for, lol.
Mach 3 or bust. There's nothing better out there. It cleans easily (the hairs don't get stuck between the blades), shaves CLOSE, and is cheaper than those 50 blade cartridges. I will say though, that single side razor on the Fusion, is amazing...to bad the rest of the razor sucks...
Word from the wise though, there ARE counterfiet blades out there...so DO NOT buy those bulk razors you see on eBay and buy from your stores. They're fake and IMMEDIATELY noticeable when you take your first swipe. the barcodes even scan and the packaging is identical. A disposeable, cheap, single blade razor shaves better than those POS's.
