Go natural. "All shampoos contain cleansers," explains Christyn Nawrot, a regional educator for Phyto. But those with naturally derived cleansers are less apt to rob your hair of vital oils. (Phyto, Lavett & Chin, Ojon and Aveda use natural cleansers in all of their shampoos.)
Eat more salmon. Omega-3 rich foods like salmon and sardines help seal in shine. Distilled fish oils or DHA supplements will work, too.
Be a bran lover. Bran is rich in vitamin B, which may slow hair loss and promote hair growth. Other B-rich victuals include beans, peas, carrots, cauliflower, soybeans, nuts, and eggs.
Use products properly. For maximum benefits, before applying shampoo or conditioner, emulsify them in your hands. Then massage onto roots (where hair is most porous), crown and finally, down sides of hair.
Say yes to avocados. Avocados and avocado oil may prevent some funky stuff that kills hair follicles -- dihydrotestosterone (DHT) -- from getting where it needs to go.
Don't overwash. "Shampooing every day is drying to your hair and scalp," says Rodney Groves, a stylist at the Vartali salon in New York City. Instead, aim for two to three times a week - and on off days, rinse with water and condition only your ends.
Stock up on green tea. Brew a strong pot, cool it, then give your head a rinse to help kill off dandruff-causing fungus. Incidentally, if you drink green tea, the caffeine in it may help slow balding, too.
