Don’t let Popeye’s bald pate fool you: Spinach is a healthy-hair secret weapon. It’s full of iron, which delivers enriching oxygen to your hair follicles. If you really want to lunch for luscious locks, also chow down on eggs (for stengthening protein), salmon (for shine-ifying omega-3s) and bell peppers (for free-radical-eradicating vitamin C). For all the brushing, washing, treating and styling that go into hair care, the real key to beautifully healthy hair is a beautifully healthy lifestyle.
