Summarize:

Natural oils and residue from styling products can weigh the hair down, causing it to look flat and lifeless. Regular rinses with shampoo will strip away this buildup and give thinning hair some much-needed lift. Start shampooing three to four times a week (about every other time you shower), assuming you don’t already, and finish with a blow dryer to give your hair an extra fluffy texture.   Choose shampoos and conditioners that are formulated to make hair more voluminous. You can also find shampoos and conditioners designed specifically for thinning hair.  Avoid oversaturating newly-washed hair with greasy products. These will reduce volume and leave it limp. No combover is going to cover a crown with an erratic balding pattern. Keep your hair short and neatly groomed to prevent pervasive hair loss from commanding too much notice. Use a razor to do away with stray tufts that stand out on darker colored hair.  Multiple small bald spots can be even more noticeable than one big one. If you’re balding all over, including the back and sides, you may have little choice but to opt for a short buzz or clean-shaven cut. A fashionable mustache, goatee or beard will call attention away from flagging head hair and instead complement your other features. This can suggest a graceful maturation in the way you present yourself. Well-kept facial hair also tends to make older men look more distinguished, showing that you take your appearance seriously.  Sprout a layer of thick stubble for youthful, rugged air, or play up your masculinity with a full beard.  Facial hair is always in style, and can stand on its own no matter how much (or little) hair you have on your head.
Wash your hair every other day. Shave patchy balding spots. Grow out your facial hair.
