I came across this inforamtion on Dr. Roizen and Dr. Oz's website (RealAge.com) and thought I would share it:
"The Healthy Hair Diet:
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.
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.
Say no to animal fat -- and red meat -- if you’re losing hair. They can lead to more DHT production and hair-follicle damage.
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."
