Been spotting one too many grey strands on your head lately? Well, it's unsettling and depressing for many. And while aging and genetics remain the primary causes of this unwelcomed transformation, science also blames nutritional deficiencies for accelerating the process.

According to a study published in the International Journal of Dermatology, people experiencing premature greying often had lower levels of Vitamin B12 , zinc , copper , and more, all of which are vital for the production of melanin, the pigment that provides the hair its natural colour.

While you could be eating a healthy diet packed with these nutrients and may still get grey hair because of the genetic history, this step could help prevent the process from accelerating further as well.

Protein (Keratin)





You could not count on your fingers the number of hair care products that advertise having keratin in them. Have you ever wondered why? It's because keratin is the main structural protein in the hair. However, it depends on dietary protein for its regeneration and a protein-rich diet in the form of eggs, poultry, fish, beans and nuts is a must.

Vitamin B5

Also known as Pantothenic acid, Vitamin B5 is present in beef, mushrooms, avocados, nuts and seeds, yogurt, oats and broccoli. The vitamin supports red blood cell formation and energy production both of which aid in scalp and follicle health.

Vitamin D





Deficiency in Vitamin D has been linked to premature greying and lowered melanin production, both of which are damaging for hair health. Thus, sitting in the sunlight and consuming fortified foods, fatty fish, eggs and more will do you much good.

Biotin Also known as Vitamin B7, Biotin is vital for hair growth and strength as its deficiency may contribute to hair thinning and premature greying. Foods like nuts, seeds and whole grains along with legumes and leafy greens are rich sources of the nutrient.

Zinc



Zinc adds to the process of protein synthesis and protects hair follicle cells from oxidative stress. The nutrient is found in beans, whole grains, red meat and oysters.
