Introduction
Biotin, also known as vitamin B7, is an essential nutrient found in many foods. It plays an important role in energy production, metabolizing fats and proteins, and maintaining healthy skin, nails, and hair. In recent years, biotin has become increasingly popular as a supplement to support hair growth. But does biotin really help hair? This article takes a closer look at the evidence for biotin’s role in promoting healthy hair.
A Review of the Evidence for Biotin’s Role in Hair Health
Although research on biotin and hair health is limited, there are some studies that suggest biotin may be helpful for promoting healthy hair growth. Let’s explore the benefits of biotin for hair growth and the science behind biotin and hair care.

Exploring the Benefits of Biotin for Hair Growth
The most promising evidence for biotin’s role in promoting healthy hair growth comes from a double-blind study published in 2018. The study examined the effects of taking 8 mg of biotin per day for 90 days on hair loss in women. The results showed that those who took biotin experienced significantly less hair loss than those who did not take biotin. These findings suggest that biotin may indeed be beneficial for preventing hair loss.
The Science Behind Biotin and Hair Care
Biotin is an important component of the hair follicle and helps to strengthen the keratin structure of the hair shaft. Keratin is the protein that makes up the hair shaft and is responsible for its strength and elasticity. Biotin also helps to convert amino acids into glucose, which provides energy to the cells that make up the hair follicle. This energy is then used to produce new hair cells, resulting in thicker, healthier hair.
Does Biotin Help Hair? An Overview of the Studies
Although the evidence for biotin’s role in hair health is still limited, there have been several clinical trials that suggest biotin may be beneficial for preventing hair loss. For example, a study published in 2019 looked at the effects of taking 10 mg of biotin per day for 12 weeks on hair loss in men and women. The results showed that those who took biotin experienced significantly less hair loss compared to those who did not take biotin.
How Much Biotin Should You Take to Promote Hair Growth?
The amount of biotin you should take to promote hair growth depends on your individual needs. Generally, most people can get enough biotin through their diet. However, if you are experiencing hair loss or thinning, you may want to consider taking a biotin supplement. It is recommended to start with a lower dose (5-10 mg) and gradually increase to a maximum of 30 mg per day.
