“For hair growth, you want herbs that are high in minerals and nutrients, but primarily minerals like iron. I always encourage people to ingest their herbs by steeping them in water to make a tea, which helps the absorption rate,” she says. “A perfect example is alfalfa tea. The alfalfa plant (aka alfalfa grass) is a natural source of iron, antioxidants, and other minerals, so I always recommend it for hair health.”*
Certified trichologist and founder of Advanced Trichology William Gaunitz, FWTS, agrees: Iron is the most critical mineral for the hair.* “Ferritin is your iron storage protein, and when that is low because you don’t have enough iron regularly input into your diet, your hair volume will decline to compensate for your body’s need for iron.” Gaunitz says the hair will only return once there’s enough iron being consumed on a regular basis. Alfalfa tea isn’t the only option either–iron-rich foods include beef, chicken, eggs, spinach, sweet potatoes, and beans. Always speak to your doctor before adding an iron-containing supplement to your routine.
It’s not just iron that the herb is high in. One cup of alfalfa sprouts contains 5% vitamin C and 13% vitamin K, giving it antioxidant properties too.* Antioxidants can support hair growth by improving scalp health and neutralizing oxidative stress, one cause of shedding.
