What are the Benefits of Brewers Yeast for Hair?

Updated April 17, 2017

Some of the many benefits of brewer's yeast for hair include treatment for baldness, treatment for preventing grey hair, and adding strength and shine. Brewer's yeast contains a mix of the B vitamins, which are necessary for hair growth and maintaining hair health. Brewer's yeast is not the same as baker's yeast. While brewer's yeast is usually found in certain yoghurts, fruits, vegetables, and alcoholic beverages, baker's yeast is typically used in making yeast rolls and other baked goods. The difference in the two types of yeast is the fermentation: baker's yeast rises, while brewer's yeast does not.

Gray Hair

As people begin to age, certain diseases such as thyroid disease and diabetes can cause the hair to turn from its natural colour to grey. Adding brewer's yeast, along with B-complex vitamins, will help hair maintain its natural colour without having to spend money on expensive colour treatments at the salon.

Male- and Female-Pattern Baldness

Brewer's yeast is an excellent source of biotin. Biotin is a B-complex vitamin, the lack of which is one of the primary causes of baldness in men and women of any age. Biotin is one of the building blocks of hair cells in the body. Hair cells are among the most active cells in the body, and need enough biotin in order to be able to keep the pace of the division and regeneration of hair cells.


Brittle hair is caused by many factors including ageing, dietary deficiency and inadequate blood circulation to the scalp. Brewer's yeast contains many B vitamins, which are necessary for hair growth, as well as nutrients that improve blood circulation to the scalp to improve the overall strength of the hair follicle.


Once the hair begins to grow, brewer's yeast adds a healthy shine so that the hair has more life and bounce, as well as definition and texture.

Dosage Information

Because brewer's yeast is meant to be used as a dietary supplement, the amount you need to take each day is very small. In addition to food sources of brewer's yeast such as fruits and vegetables (figs, pickles, tomatoes, and olives) and beer, you should take one teaspoon dissolved in either food or a glass of water.


Use caution before taking brewer's yeast if you are prone to yeast infections, have diabetes, or are taking certain types of MAO inhibitors.


Brewer's yeast can be found in the vitamin and supplement aisles of many pharmacies, grocery stores, department stores and vitamin speciality stores.
