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

"The older we get, the more our hair is put through with color, styling, and limited time. Hair strands become smaller because of pigment loss and become fine and thin," explained Shelley Gregory, a colorist at Atelier by Square Salon and an ambassador for L'Oréal Professionnel. "Keeping that healthy, young hair glow is easy with an in-salon quick glossing service — I like using L'Oréal Professionnel DIA Light ($18) — followed by a professional haircare treatment to protect and preserve the color, like L'Oréal Professionnel Color Powermix. This can take years off and give your hair back its shimmer."

She recommended having your hair glossed twice a month, or you can try an at-home product, such as L'Oréal Professionnel Vitamino Color AOX Masque ($33).
