Hair Repair: How to Get Strong, Shiny Hair

Mane Mission: Shine

Radiance is the ultimate sign of hair health. When its cuticles are flat, hair is reflective, says Charles Baker Strahan, a celebrity stylist for Herbal Essences.

Tress test: Grab a hand mirror and stand by a window to examine clean hair in natural light. You should notice a band of light that spans your head. Don't see it? Get glossy with these easy tweaks.

Handle with care. Treat your hair like your favorite cashmere sweater: Avoid any friction. Blot hair dry rather than vigorously rubbing it with a towel. When blow-drying, Jet Rhys, a salon owner in San Diego, suggests that you use the nozzle attachment to concentrate the air down the hair shaft -- the direction in which the cuticle lies.

Do a detox. Styling products can leave behind a milky residue that regular shampoo can't cut through. For a deep clean that won't strip hair of its natural oils, mix one tablespoon each of lemon juice and vinegar with a dollop of your regular shampoo. Lather for about two minutes and rinse thoroughly. If you need extra sheen, mist your hair with Aussie Heat Protecting Shine Spray ($4, drugstores) before blow-drying.
