Stage One: Going
If your hairline is receding, don't grow out your bangs to compensate—that'll only make you look like you've lost more. "It's one of the biggest mistakes men make," says Joe Martino, a stylist at the Orlo salon in New York. Instead, trim the middle of the hairline where it dips down so it's even with the sides.

Stage Two: Going
When the hair on top of your head thins, it can make your face look round. To offset this, have your hair cut in a square shape, with the sides closely cropped and the top no longer than an inch. "You don't want the hair on the sides to be thick and heavy, because then the bald patches pop out," Martino says.

Stage Three: Gone
Unless your scalp is exquisitely shaped, a shaved head will only call attention to the fact that you don't have hair. Instead, get your hair cut as short as you're comfortable with. "I have a guy who gets a cut every two weeks, which is a lot," Martino says. "But no one ever tells him he needs a haircut."

If you've noticed a few slate-colored strands up there, don't panic. And definitely don't blast your scalp with Grecian Formula. Instead of coloring all of your hair, adjust the salt-to-pepper ratio with a natural-looking semipermanent dye that blends away about a quarter of the gray. And have a professional do it. Make sure to pick a color one shade lighter than your hair—a dye in the same hue can look unnaturally dark. L'Oréal Professional Homme and Redken for Men are both good options that will cost you $20 to $70 per application. Don't forget to tip well, because you'll be back in four to six weeks when the magic fades.
