Your Hairstyle Could Actually Be Aging You — Here Are 11 Ways to Avoid That

Another way to maximize shine and keep hair healthy is to not wash your hair every day and to shampoo strategically, said Bang. "Overwashing strips your hair of its natural oils, resulting in brittle hair and unwanted split ends," explained Bang. "When shampooing, it's important to apply shampoo only at the roots, as it is the oiliest area. Condition only the middle shaft of the hair down to the ends, rinsing with cold water to rehydrate and seal the cuticle. In between washes, dry shampoo is your best friend!"

Also try using a shampoo that's formulated specifically for aging hair. For example, Alterna Haircare Caviar Anti-Aging Replenishing Moisture Shampoo and Conditioner ($34 each) hydrate and protect hair from future damage and make hair noticeably softer, shinier, textured, and more manageable.
