Which Nutrients Prevent Hair Loss?

Written by Dr. Griffin

Anyone can experience hair loss at some point in life. The problem can happen due to a combination of factors, including heredity, hormonal changes, and medical conditions. With that in mind, what many patients with thinning hair want to know is: Does hair transplant surgery work? The Philadelphia area’s Dr. Thomas Griffin believes that this procedure can be highly beneficial for many people who are experiencing hair loss.

The surgery makes hair become fuller and thicker to improve your self-esteem and appearance while still producing a natural-looking hairline.

If you want to maximize the results from hair transplants, there are also some other targeted health solutions that can improve the growth and thickness of your hair, such as over-the-counter supplements, like biotin. Sometimes, if you’re not getting enough of certain vitamins and minerals in your diet, the deficiency can make hair loss worse. 


Biotin, also known as vitamin B7, is a water-soluble vitamin that’s found in most hair growth products, along with many shampoos and conditioners. Your body uses biotin to promote the production of keratin, a protein that forms part of the hair, skin, and nails. The recommended dose is 5,000 to 10,000 mg per day.

Vitamin A

Vitamin A promotes cell growth, so when you’re not getting enough of it from your diet, the lack can lead to hair growth problems. Vitamin A also encourages the production of oils to keep the scalp and hair healthy. However, excess Vitamin A can cause hair loss, so proper dosing is essential. The recommended daily dose is 900 mg for men and 700 mg for women.

Vitamin C

Free radical damage can be very harmful for your hair. Vitamin C is known for its ability to boost the immune system, but it also helps to strengthen hair because of its antioxidant properties. It promotes blood circulation throughout the body, including the scalp, to support the growth of healthy hair. The recommended dose per day is 75 to 90 mg.


Studies have shown that there’s often a link between hair loss and iron deficiency (anemia). This mineral helps oxygen to get to cells more effectively. Iron and ferritin levels are measured and, if low, supplementation with 325 mg a day is recommended.


Zinc supports the growth and repair of hair tissue while also ensuring that hair follicles and oil glands function properly to stop hair fall. A safe doze of zinc is 15 to 25 mg a day.
