However, vitamin B12 may give you the appearance of fuller and thicker hair because the increase in oxygen to hair follicles can help stimulate the replacement of lost strands. Vitamin B12 may also help give your hair an overall healthier appearance since intake of enough B12 is responsible for stronger hair shafts.
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.
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.
Vitamin B12 is one of those vitamins because it nourishes your hair follicles through production of oxygen-rich red blood cells, which promote healthy hair growth. In turn, satiated hair follicles not only provide fertile ground for growing hair, but vitamin B12 is also believed to strengthen and condition your hair.
1. Biotin. Biotin (vitamin B7) is important for cells inside your body. Low levels of it can cause hair loss, skin rashes, and brittle nails.
Iron deficiency (ID) is the world's most common nutritional deficiency and is a well-known cause of hair loss.
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Vitamin B. Complex B vitamins play a role in hair growth, and are “essential for metabolism and nervous system function,” says Dr. Green. “It is no wonder that B vitamins like vitamin B7 (biotin) and B12 are important to strengthen and condition the hair.”
Vitamin A
And vitamin A is essential for your cells to grow, which, in turn, helps your hair grow. Your skin glands also benefit from vitamin A, using it to produce sebum. The sebum (oil) keeps your scalp moisturized and keeps hair healthy. But don't overdo it with vitamin A, as too much can cause hair loss.

Vitamin B12 may also help give your hair an overall healthier appearance since intake of enough B12 is responsible for stronger hair shafts.
It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.
Vitamin B12 is a nutrient that helps keep your body's blood and nerve cells healthy and helps make DNA, the genetic material in all of your cells. Vitamin B12 also helps prevent megaloblastic anemia, a blood condition that makes people tired and weak.
When vitamin B12 levels are low, your hair follicles may not be able to grow new hair as efficiently, resulting in hair loss. A vitamin B12 deficiency can also cause symptoms of anemia, which is associated with low iron levels, hair thinning, and hair loss.
No interactions were found between biotin and Vitamin B12.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
But if you need more vitamin B12 than what your diet provides, that's when supplements can come in. If you are low in vitamin B12, a common recommended dose for oral supplements is about 1,000 mcg daily.
For healthy hair and stronger nails, there is a natural alternative to biotin — silica.
