The best way to hide thinning hair is to try a new hairstyle. One of the biggest cover-up mistakes men make is that they try to grow out their hair and continue to sport the same look—bad idea. And don’t get me started on the comb-over—you’re not fooling anyone. Consider a scissor-cut hairstyle, short to medium length. This will allow you to style your hair with a paste or putty (stay away from gels), and make your hair look fuller.
If you’ve lost a great deal of hair and this suggestion won’t work, your next realistic choice would be to get a low buzz cut; this way your hair can blend easier with those thinning areas. It’s perfect for keeping everyone’s eyes on your face instead of your bald spot.
