Does Biotin Really Help Hair Growth? Here’s What You Need To Know

Does biotin hair growth really work? We’ve got the answer below, as well as biotin hair benefits and how to use the popular ingredient in your hair routine. 

What is biotin?

Before we get into biotin hair benefits, it’s important to understand what it is and how it works. Biotin is a water-soluble vitamin that falls within the vitamin B-complex family. It helps your body break down glucose in carbohydrates into energy. It’s found in many common foods, including egg yolks, cereals containing wheat and oats, vegetables like spinach and mushrooms, and rice. 

While most people get enough biotin by eating a well-balanced diet, the Food and Nutrition Board of the Institute of Medicine recommends a daily dietary intake of 30 mcg per day to maintain good health.

Does biotin help hair growth?

Unfortunately, there isn’t enough evidence to prove that biotin hair growth is effective. According to the American Academy of Dermatology, your hair grows on average half an inch per month. Biotin might, however, help keep your hair strong during the grow-out process by improving your body’s keratin infrastructure. Keratin is a type of protein that makes up your hair, skin, and nails. 

If you’re dealing with breakage or hair loss, it can seem like it’s taking your hair even longer to grow. Some doctors or hair care professionals may recommend biotin hair vitamins or products to help strengthen your hair and keep it from breaking off.

Can biotin ruin your hair?

There’s no evidence proving that biotin is harmful to your hair. In fact, a deficiency in biotin can potentially cause you to experience hair thinning or loss. However, biotin deficiency is rare. 

How can I add biotin to my hair?

Biotin hair products are a great way to test how the ingredient works for your mane. While it may not be scientifically proven to speed up the hair growth process, biotin can help keep your strands healthy and strong while you’re trying to achieve your goal length.
