Yes, low vitamin D can contribute to premature graying of hair, as research shows a link between vitamin D deficiency and reduced melanin production, impacting hair pigment, though genetics and other nutritional factors (B vitamins, iron, copper, calcium) also play significant roles. Addressing vitamin D deficiency through diet or supplements, after a blood test, may help restore color in some cases, but reversal isn't guaranteed, notes Healthline.
A review of research suggests that proper supplementation may reverse premature graying in those who are deficient in certain nutrients, including iron, vitamin D, and vitamin B12. However, even though some supplements are specifically sold as “anti-graying,” there aren't any studies that prove they work.
A severe vitamin D deficiency can cause hair loss (as well as other issues), but not gray/white hair.
Here are 10 unexpected signs of a vitamin D deficiency that may surprise you.
When vitamin D levels are low and the body isn't able to properly absorb calcium and phosphorus, there is an increased risk of bone pain, bone fractures, muscle pain, and muscle weakness. In older adults, severe vitamin D deficiency (levels less than 10 ng/mL) may also contribute to an increased risk of falls.
“This is one of the first studies to show that women with low levels of Vitamin D gain more weight, and although it was only two pounds, over time that can add up,” said study author Erin LeBlanc, MD, an endocrinologist and researcher at the Kaiser Permanente Center for Health Research in Portland, Oregon.
However, research suggests that Vitamin B12 deficiency may also contribute to premature graying. By incorporating Vitamin B12 into your diet or through supplementation, you can help prevent premature graying and maintain your hair's natural color for longer.
When deficiency disrupts vitamin D in your scalp, the anagen (growth) phase shortens. This prematurely pushes more resting follicles into the telogen (rest) phase. Excessive shedding occurs, resulting in thinner hair. Research clearly demonstrates this link.
Sometimes, melanocytes - the pigment-producing cells in hair follicles may start functioning again, leading to darker hair regrowth. This is rare, but not unheard of in people recovering from hormonal shifts, an illness or medication adjustments. The other possible cause is your medication.
Vitamin deficiencies such as low iron, copper, b12, and hypothyroidism can lead to premature greying. Compelling evidence suggests that prolonged intense stress can cause premature greying. Oxidative stress from the sun and tanning damages the pigment cells of the hair root causing hairs to become grey.
It is less known that magnesium deficiency can slow down hair growth and cause premature hair graying. It's estimated that well over 80% of adult Americans do not consume the desired daily amount of magnesium.
As of now, there are no effective treatments that can reverse or prevent gray hair.
Taking too much vitamin D causes a buildup of calcium in the blood (hypercalcemia), leading to signs like frequent urination & intense thirst, digestive issues (nausea, vomiting, constipation), muscle weakness & fatigue, bone pain, and confusion or disorientation, all stemming from this calcium overload.
Vitamin D deficiency typically causes diffuse thinning across the entire scalp rather than in specific patterns like male or female pattern baldness. It's often accompanied by other symptoms of vitamin D deficiency, such as fatigue and muscle weakness.
You can begin to restore hair growth immediately, with a full recovery time usually taking between 6 and 8 months for those with long hair. For those with shorter hair, new hair growth can begin to look thicker and fuller within 2-4 weeks.
Vitamin D deficiency can manifest as dry, brittle hair that breaks easily. Moderate to excessive shedding and thinning hair may also occur. Studies have even proven that low levels of vitamin D are also responsible for premature graying. Diagnosing vitamin D deficiency involves a simple blood test to check levels.
To quickly increase Vitamin D, combine safe sunlight exposure (10-20 mins daily without sunscreen for lighter skin), taking high-dose Vitamin D3 supplements (consult a doctor first), and eating foods like fatty fish (salmon, tuna), egg yolks, fortified milk/cereals, and sun-exposed mushrooms, ensuring you take supplements with a fat source for better absorption.
ca and vitamin D3 levels were significantly lower in patients with premature graying of hair. Vitamin D3 levels were either deficient or insufficient in all the individuals of case group indicating probably an important role in pigmentation of the hair.
3. Diet and Nutrition for Melanin Production
Curlzvit Tablet is a dietary supplement for premature greying and hair fall. It supplies hair with fortifying substances like biotin, PABA, inositol and calcium pantothenate. It maintains the hair structure, strengthens hair, and increases the resistance of hair to mechanical and chemical damage.
Some of the effects of vitamin D deficiency include:
Calcium and vitamin D supplementation is associated with decreased abdominal visceral adipose tissue in overweight and obese adults.
Certain groups of people are more likely than others to have inadequate vitamin D status. These include breastfed infants, older adults, people with limited sun exposure, people with dark skin, people with conditions that limit fat absorption, and people with obesity or those who have undergone gastric bypass surgery.
