At the top of the list of essential vitamins for hair growth is biotin, also known as Vitamin B7. Whenever you see vitamins for hair growth, biotin is at the top of the list. It's also important for healthy nail growth. A vitamin deficiency involving biotin causes hair loss, brittle nails, and nerve damage.
Biotin. Biotin, also known as vitamin B7, is a complex B vitamin that is often touted for having hair growth benefits. And some of that hype may actually be worth it. Biotin has functions in “creating red blood cells, which carry oxygen and nutrients to the scalp and hair follicles,” says Dr. Green.
Biotin (Vitamin B7)
Because of this, biotin is often promoted as a supplement for healthy hair, skin and nails. Biotin is produced naturally in your small intestine, but it's also found in certain foods.

B vitamins
B vitamins help with hair growth because they play a key role in producing red blood cells, which carry oxygen to the scalp so that hair follicles can generate new hair.

Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
Will Hair Grow Back From B12 Deficiency? Yes! Your hair will grow back as soon as you treat the deficiency. On restoration of vitamin B12 in your body, your hair cells will replicate adequately and support your hair follicles to grow healthy hair.
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.
Vitamin B12
Although a deficiency in B12 may lead to hair loss, research does not suggest that people who do not have a deficiency can improve their hair growth by using a supplement. Nevertheless, getting enough vitamin B12 is essential for overall health.
When it comes to the issue of vitamin B12 vs B complex, both types of vitamins are crucial. If you're lacking B12, consume more of it via supplements or food. If you're lacking vitamin B in general, consider B complex vitamins instead. Overall, both vitamins are essential nutrients.
It helps in the stimulation of hair follicles by increasing their blood supply. Additionally, the B complex for hair also reduces the chances of hair fall by reducing oxidative stress. It was found that people with a deficiency in B complex for hair were also experiencing increased hair fall.

In addition, vitamin B6 supports healthy hair growth because of its role in protein metabolism. Vitamin B6 also ensures that hair cells have access to the amino acids (building blocks of protein) needed to make hair proteins.
The reason they are classified as different vitamins, however, is because they all serve a slightly different specific function. For example, B7 helps improve your hair and nail health, while too little B12 or B6 in your diet could cause you to have anemia. B7 (also known as biotin) is part of the B vitamin complex.

There's no real harm in taking vitamin B complex and biotin together. The vitamins are water-soluble, so any excess is removed from your body when you pee, per the Harvard T.H. Chan School of Public Health.
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.
The good news is that hair loss due to vitamin D deficiency is usually reversible. Once levels of vitamin D are increased, hair follicles will typically begin to function properly again and hair will start to regrow.
