“Vitamins are essential for healthy hair growth and may help in preventing hair shedding and thinning,” says Michele Green, M.D., a cosmetic dermatologist in New York. “The best vitamins for hair growth include B vitamins, vitamin D, vitamin E, zinc, biotin and iron.
Biotin is a B-complex vitamin that promotes skin, hair and nails health.
Vitamin D stimulates hair follicles to grow, and so when the body does not have enough, the hair may be affected. A vitamin D deficiency may also be linked to alopecia areata, an autoimmune condition that causes patchy hair loss.
One of those vital nutrients is B12, also known as cobalamin. B12 promotes healthy hair growth by assisting in the production of oxygen-rich red blood cells, which feed hair follicles.
Vitamin C is one of the most effective nutrients to help grow and strengthen hair, says Guy Parsons. “Vitamin C helps build collagen, which is highly important for hair growth, but maintaining the strength of hair is just as crucial,” Guy says.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss. Vitamin B2 (riboflavin) is a component of two important coenzymes: flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) [22].
Magnesium has a direct impact on hair growth. It regulates hair follicle production and the overall hair growth cycle, making it an essential mineral for healthy hair growth. When magnesium levels are low, hair follicles go into a resting phase and stop producing new hair, leading to hair loss.
Magnesium glycinate is a combination of two molecules, magnesium and amino acid glycine. Combining magnesium with amino acid boosts its bioavailability. It means that it is one of the best magnesium supplements to prevent hair loss.
Vitamin D can indeed cause hair loss, but it's rare. Although the precise role of vitamin D in hair growth isn't well understood, research shows that vitamin D receptors play an important role in the anagen phase of the hair follicle cycle — the phase in which new hairs grow from the follicle to their full length.
How Much B12 Should I Take Daily For Hair Growth? The lowest amount recommended that should be traceable in your body is 2.4 mcg. While you are looking for a difference in your hair growth you can increase this dosage to 3 mcg and beyond.

Which Protein Is Best For Hair Growth? Keratin is a fibrous structural protein that makes up your hair. Lot of protein-rich foods and biotin [3] help in the synthesis of this protein needed for your hair. Hair cuticles [4] absorb keratin and make the hair look full and glossy with protein treatments.
Zinc is also an essential nutrient for hair growth, and a severe zinc deficiency could lead to hair loss.
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
That is why we recommend supplementing with between 5,000-10,000 IU per day in order to achieve healthy vitamin D levels (40-80 ng/ml).” The key to resilient, strong hair less prone to falling out lies in the follicles.
