While a poor diet can affect the health of your hair, there's no one food or drink that can help it grow faster. However, there is evidence that lysine and vitamin B-6 may be beneficial, so including drinks rich in these nutrients may help hair health and growth. If you're concerned about the health of your hair, talk to your doctor -- changes in your hair might signal an underlying medical disorder that needs treatment.

Chocolate Almond Milk

Women with high rates of hair shedding seem to benefit from the amino acid lysine, according to a 2002 article published in Clinical and Experimental Dermatology. Ready-to-drink chocolate almond milk is a source of this essential amino acid, and including it in your diet may help up your intake for better hair. Regular almond milk, on the other hand, is not a significant source of the amino acid, meeting only 1 percent of the daily value.

For more lysine, nonfat cow's milk is a good choice, meeting 15 percent of the daily value. Nonfat cow's milk is also a source of vitamin B-6, meeting 5 percent of the daily value. A Polish study published in 2001 in Wiadomości Lekarskie found that vitamin B-6 helped improve hair health, as well as limit hair loss, in a group of women with alopecia. A more recent study published in 2013 in the Archives of Dermatological Research also notes that vitamin B-6 supplementation helped prevent the loss of hair in mice receiving chemotherapy. The mice in the study were also given cysteine, which may have influenced their lack of hair loss.

Soy Protein Drink

A soy-based protein powder that you can make into a drink is also a good source of both lysine and vitamin B-6. One scoop of the powder mixed with water meets more than 100 percent of your needs for lysine and 4 percent of your daily needs for vitamin B-6. You can also mix your protein powder in almond or cow's milk to increase the hair-promoting nutrient content of either drink.

When it comes to nutrition and hair health, you might get more benefit from eating an overall healthy diet. A study published in 2015 in Dermatology Research and Practice notes that hair loss increases with poor intakes of protein, essential fats, vitamins and minerals. Including fruits, vegetables, whole grains, lean proteins and healthy fats, in addition to nutrient-rich beverages, may offer the most benefits to your hair and its growth.
