Do you think you need expensive medicines, vitamins, or creams to prevent hair loss or baldness? Change your views! Due to the availability of one or more of these four follicle-boosting nutrients: iron, zinc, lysine, and dietary antioxidants, research suggests that the 20 items on this list can all help to halt and even reverse hair loss.

Canned clams

As well as being the world’s most common nutritional deficiency, a lack of iron is a well-known cause of hair loss. What may be less well-known is the fact that canned clams are among the richest food sources of iron.

Oysters

Seafood goes two for two at the top of the iron-rich list, with oysters containing 7.8 mg of the nutrient per 85-gram (three-ounce) serving. Oysters have the added benefit of being packed with zink, up to 71 mg per 85-gram (three-ounce) serving—which has been shown to promote hair growth.

Pumpkin seeds

Vegetarians and vegans looking to get more hair-saving iron and zinc into their diets can snack on pumpkin seeds, which contain around 4.2 mg of iron and 2.9 mg of zinc per 28-gram (one-ounce) serving.

Indian gooseberries

This exotic edible is absolutely jammed with antioxidants: 261.5 millimoles per 100-gram (3.5-ounce) serving when dried. Oxidative stress has been linked to hair loss, and because antioxidants prevent this type of stress these compounds are likewise seen as helping to keep your hair on your head.
