Lackluster locks? Salt water, chlorine, minerals found in city water, and styling product buildup all rob hair of its healthy shine. Then there's summer's smoldering heat. "Heat makes the hair cuticle swell so it absorbs light rather than reflects it," explains Abbey Theis, a colorist at Arrojo Studio in New York and a spokesperson for Sebastian Professional.
The Solution: Invest in a quality boar-bristle brush that can help distribute the oils on your scalp into your hair. Brush from the scalp to strand for natural shine. To restore luster, look for styling products containing silicones. A great shine serum or spray is a must.
Prevention: "Dull hair is usually the result of using too much heat, heavy styling products, or overprocessing hair," says Takisha Sturdivant-Drew, of Pantene. Steer clear of anything that weighs hair down or causes it to look dirty, such as oil-based conditioners, waxes, sculpting muds, and hairsprays.
Wash Smart: If you swim in a chlorinated pool, use a clarifying shampoo weekly and rinse thoroughly. This helps remove chlorine buildup.
