##Biotin and hair growth: myth or truth?

Biotin, also known as vitamin B7 or vitamin H, is a water-soluble vitamin that plays an important role in the body. It is often associated with hair growth and touted as a dietary supplement to promote healthy hair, skin and nails. But is biotin really a miracle cure for hair growth, or is it just a myth? In this article, we'll take a closer look at biotin's effect on hair growth and find out whether it can actually help promote faster, healthier hair growth.

##What is biotin?

Biotin is an essential vitamin that belongs to the group of B vitamins. It plays an important role in the metabolism of fats, carbohydrates and proteins in the body. Biotin is also needed for skin, hair and nail health as it supports the production of keratin, a protein that forms the main component of hair, skin and nails.

##How does biotin affect hair growth?

Biotin supports hair growth by promoting the production of keratin. Keratin is a structural protein that strengthens hair and gives it elasticity. It is the keratin that is responsible for the strength and shine of the hair. A sufficient amount of biotin in the body is therefore important for healthy hair growth.

##Studies on biotin and hair growth

There are some studies that have examined the effects of biotin on hair growth. One such study was published in 2015. In this study, 120 participants with thin hair took biotin as a dietary supplement. After 90 days, most participants showed a significant improvement in hair quality and hair growth. However, the results were mixed, and not all participants showed the same improvement.

Another study examined the effects of biotin on people with genetic hair loss. In this study, participants took biotin as a dietary supplement for 180 days. It turned out that taking biotin led to a significant improvement in hair thickness. The study concluded that biotin as a dietary supplement may have a positive effect on hair growth, especially in people with genetic hair loss.

These studies provide evidence that biotin can actually have a positive impact on hair growth. However, further studies and larger research are needed to better understand the exact mechanisms and effects of biotin on hair growth.

##Biotin deficiency and hair loss

A biotin deficiency can lead to hair loss. Since biotin is required for the production of keratin, a deficiency of this vitamin can weaken hair and lead to hair loss. Symptoms of a biotin deficiency also include brittle nails and skin problems. It is therefore important to ensure that the body is supplied with sufficient biotin to support healthy hair growth.

##How can you take biotin?

Biotin is found in many foods, including eggs, nuts, seeds, whole grains, and certain vegetables such as avocados and spinach. The recommended daily dose of biotin is around 30-100 micrograms. However, in some cases a higher dose may be required, particularly in people with genetic hair loss or a diagnosed biotin deficiency. In such cases, it may be advisable to take biotin as a dietary supplement. However, it is important to always consult a doctor before taking any type of dietary supplement.
