A Low-Folate Diet Can Turn Your Hair Gray Prematurely.
If you’ve noticed some stray gray hairs popping up more frequently, it might be time to reconsider your diet. Folate deficiency is associated with hair turning gray much earlier than it normally would. Melanocytes are cells that produce the pigment melanin, which gives our skin, hair, and eyes their color. As we age, melanocytes produce less melanin, causing your color to fade over time. In the case of hair, all the pigment is eventually lost, leaving the hair gray or white. Folate plays a role in hair pigmentation and strength. So, if you don’t get enough folate in your diet, you may notice changes in your hair and skin color. Of course, folate deficiency isn’t the only reason for premature graying, which can also be caused by genetics and some health conditions. But missing out on certain nutrients in your diet is one of the number one reasons that hair goes gray before its time. In addition to folate, diets that lack iron, vitamins B12 and D, and the mineral selenium are also linked to premature graying. Fortunately, graying caused by nutritional deficiencies can be reversed by increasing the intake of the missing nutrients.
