Due to their high concentration of essential fatty acids naturally found in skin cells (which help to keep your skin smooth and supple), avocados are an age-old beauty secret. When topically applied to the hair and scalp, they have the added ability to stimulate collagen and elastin production. Mix a little avocado with sour cream (which contains lactic acid to help exfoliate dead skin and clean up buildup on the scalp) and apply to your hair and scalp for about ten minutes before washing off.
These nuts will make your hair grow faster and thicker due to their high biotin content. One cup contains nearly one-third of your daily requirement. You should be able to see the results in a month or two of adding them to your diet.
Iron is an essential mineral that your hair cells require. In fact, a deficiency of iron in the body may cause hair loss. When your body is running low on iron, oxygen and nutrients are not getting transported to the hair roots and follicles adequately which can inhibit growth and make your strands weak.
4. Yellow peppers
Yellow bell peppers have nearly five and a half times more vitamin C than oranges (341 milligrams, as opposed to 63). This is very good news for your locks—vitamin C is an antioxidant that strengthens the hair shaft and hair follicles, as well as prevents breakage.
Zinc deficiency has been known to cause hair loss and poor scalp conditions, and oysters are loaded with zinc—just three ounces contains 493-percent of your daily value. But not just any oysters will do: Steer clear of the ones caught in the Gulf of Mexico, which may contain unusually high levels of Cadmium due to the 2010 BP oil spill.
