How are beer and hair health connected? A study explores the relationship between the two.

Researchers note that beer contains calcium, iron, selenium, zinc, protein, and vitamins D and E. After such a “frothy” treatment, hair will indeed appear healthier, according to Dr. Ryan Walter. Scientists recommend applying the beverage to the hair and leaving it on for about five minutes before rinsing with warm water.

“Beer in the hair is more like a conditioner. Hair is essentially made up of protein strands, and since various substances can stick to these strands, this can help them look much healthier than they actually are, or even improve their health by effectively conditioning them,” the doctor explained.
