Your hair changes as you age, just like your skin. Experts say it's normal for strands to become thinner, slower to grow, and even change texture over time. According to dermatologist Dr. Mona Gohara, aging affects both the hair follicle and the scalp, causing hair to lose pigment, feel brittle, and regenerate slower. Genetics plays a big role, but lifestyle factors like stress, diet, medications, heat styling, and environmental exposure can also speed up the process. Some of the most common signs of aging hair include graying, dullness, thinning, slower growth, and noticeable texture changes. Straight hair may start to feel coarser, while curly hair can gradually lose its shape. The good news is that experts say there are plenty of ways to help keep hair looking healthy. Regular scalp massages may improve circulation, while moisturizing masks, conditioners, and bond-repair treatments can help restore softness and shine. Limiting heat styling, protecting hair from sun exposure, and maintaining a healthy diet can also make a difference. For those embracing gray hair, experts recommend using conditioning products along with a purple shampoo once a week to reduce yellow or brassy tones. They also advise using lower heat settings when styling, as gray hair is often more fragile.
