Can Vitamins Promote Eyebrow Growth?

By Luann Voza ; Updated July 18, 2017

Hair growth can be affected by many factors including genes, thyroid problems, illness, medications and vitamin deficiencies. Hair growth in the eyebrows varies among individuals, with common regrowth periods based on how hair was removed. With tweezing and waxing, the hair is removed from the follicle resulting in a regrowth period of about 60 days. Hair removed by shaving will grow back faster while hair loss due to illness will have a longer regrowth period. Certain vitamin supplements, particularly the B vitamins, will help hair growth and repair.

Vitamin B5

Vitamin B5, also known as Pantothenic Acid, is considered beneficial for hair as it promotes cell growth. It is abundant in most of the foods you eat including meats, grains, eggs, vegetables and dairy. Unfortunately, most of the vitamin is lost with processed foods. Suggested dosage as a supplement is between four and seven mg. daily.

Vitamin B5 benefits your body by helping with metabolization, or the converting of nutrients to energy. As a supplement, Vitamin B is known as Calcium Pantothenate. In the form Pathenol, the vitamin is added to moisturizers and shampoos to help promote shine and nourishment.

Vitamin B7

Vitamin B7 is also known as Vitamin H and Biotin. This vitamin is recommended to treat or prevent hair loss in children as well as adults. The function of Vitamin B7 is to regulate cell growth, fatty acid production and blood sugar regulation. Sources of this vitamin include meat, oatmeal, cereal, bananas, mushrooms and eggs. However, raw egg whites can block its absorption. Recommended dosage as a supplement range from 30 to 100 mg. daily.

A deficiency in Vitamin B7 results in hair loss in various areas, including the eyebrows. Biotin is a popular ingredient in shampoos that claim to improve the health and growth of your hair. At this time, the benefits of Biotin as a shampoo ingredient are unclear and not supported by research.

Vitamin B9

Vitamin B9 is also known as folic acid or folate. It can be found in legumes, citrus fruits, whole grains, leafy vegetables, poultry, pork and shellfish. The function of Vitamin B9 is to promote tissue growth. As a supplement, it is manufactured as Folic Acid with the recommended dosage of 400 to 800 mg. daily. A deficiency in Vitamin B9 can result in poor hair growth and premature graying of your hair.


B vitamins are water soluble, which indicates that excess dosages do not remain in your body. Daily resupplying of the vitamins is necessary to avoid deficiencies. The preferred intake of vitamins is through food. Diets that are low in the food sources should include an intake of the vitamins in a supplemental form.
