Here's the thing: Going bald is natural in the aging process. It just happens. And you don't have to feel bad about it, or quite frankly, do anything to mask it. But, there are a few ways you can wear your hair that will help, if you're looking to change things up. We're here for you. So, in the interest of advice, find some below that'll help next time you're at the salon or barbershop.
For thinning hair, one of the worst things you can do is grow the hair longer, especially on the sides and back. This simply makes the thinning top look even thinner in contrast to the thicker sides and places the emphasis on the baldness. Here's my rule of thumb. Take a look in the mirror—if you see scalp exposure on top, cut the sides and back short enough to reveal an equal amount of scalp exposure. This will help provide balance and draw focus away from the thinning top. You may also wish to consider a texturized hairstyle that allows the top to be a bit messy and provide better coverage. The right haircut for thinning hair is essential.
Another great idea, if you've got a great head shape and strong facial features, is to go completely bald. This completely hides the fact that your hair is thinning. If you've got a great pair of eyes, the lack of hair brightens and draws focus to the eyes and really makes them "pop." Had my computer friend had a proper haircut or a shaved head, his look would have been spot on, but the bad cut and use of product immediately drew focus from his baby blues to his balding top. Shaving your head at home also saves you ton of money on product and trips to the salon.
If you are thinning on top, the addition of some facial hair (a neatly trimmed beard or goatee are great options) will also help draw the focus down the face and away from the top of the head. Less hair on top, combined with more hair on the face provides balance.
When your hair is thin, the last thing you'll want to do is use a product that gives separation (e.g. causes the hair to clump together in groups) as this will further enhance the scalp exposure. There are several good thickening shampoos on the market that can help buy pumping up the hair shaft a bit, so I recommend using one (I really like Tigi Bed Head for Men Charge Up Thickening Shampoo). For styling, you may wish to consider a light styling cream on dry hair to help you achieve hold and control without separation. For styling, go with a product like American Crew Light Hold Texture Lotion which will give you some control without being too aggressive for thinning hair.
Dealing with thinning hair can certainly be a challenge and so many men have so much of their self esteem tied into their hair. It can be quite discouraging, but the best thing is to simply accept the fact that you are losing it. Get a great haircut and use the right products to make the most of the hair you do have. Keep your body healthy and your wardrobe sharp and, combined with the right cut, nobody will notice (or care).
