Does Biotin Really Work For Hair Loss Prevention? Biotin or vitamin B8 contributes to the beauty and health of hair. Here are all its benefits and how to use it.

What is Biotin?

Biotin also called "vitamin B8" or "vitamin H", plays several roles in the body, and it is mainly involved in the metabolism of lipids, proteins and amino acids.
It is also involved in regulating blood sugar, hence its interest in the management of diabetes. Finally, it participates in cell renewal and the synthesis of vitamin B9 (folic acid) and vitamin B12.
Produced naturally by the body, it is made by the bacteria of the intestinal microbiota.
It can be provided through diet and consuming foods rich in biotin: legumes, nuts and seeds, egg yolk, sweet potato, etc.

It is also found in the form of a food supplement to compensate for a deficiency or improve the hair's beauty and health.

Indeed, it contributes to the maintenance of normal hair, and it is particularly indicated to slow hair loss and stimulate hair growth.
It also helps to develop more robust and shinier hair.
Biotin is one of the best dietary supplements for hair

Biotin benefits for the hair

Biotin stimulates hair growth

Biotin is particularly interesting in cases of alopecia. Indeed, it seems capable of slowing down hair loss while stimulating their regrowth.
As this review shows, it is the subject of many studies on the subject. Biotin supplementation has been beneficial for anyone with a hair problem, such as unmanageable hair syndrome. Vitamin B8 accelerates the renewal of hair cells and follicles, resulting in new hair. It promotes blood circulation in the scalp, thus providing the nutrients necessary for hair growth.
Finally, it supports the metabolism of lipids (fatty acids) and the biosynthesis of amino acids and vitamins necessary for healthy hair, such as vitamin B9.

Biotin strengthens the hair fibre.

In addition to boosting growth, it makes hair more robust and more resistant. This is why a biotin deficiency often results in brittle hair and the appearance of split ends. Vitamin B8 improves the structure of an essential protein: keratin. The latter is one of the main constituents of hair fibre, and it gives structure and strength to each hair. In addition, it protects maintains hydration and elasticity.
Biotin and keratin are therefore often combined in food supplements for the hair. They also strengthen all other skin appendages such as eyelashes and nails.

Biotin brings shine

Biotin is a precious ally in case of dull and lifeless hair. Indeed, it improves the appearance of the hair by providing shine.
Improving the nutrition of the scalp and hair follicles also increases hair density. The hair gains in thickness and volume.

How to use biotin for hair?

As a dietary supplement
There are many dietary supplements for hair health today, and they come in capsules, tablets, capsules or even gummies.
Choose a supplement with enough vitamin B8. It can be combined with minerals, trace elements (selenium, zinc, etc.), sulphur amino acids or other active ingredients such as brewer's yeast, horsetail or nettle.
The biotin/ millet combination, for example, is exciting. Indeed, millet seeds contain milia, a natural compound that promotes hair growth, as shown in this study.
Until now, offered in synthetic form, biotin can now be of plant origin. It is then extracted from the leaves or seeds of basil ( Ocimum basilicum ).

For external use
Biotin is used in the formulation of many hair products and treatments. Thus, it is found in serums, shampoos, lotions and hair masks to be applied to the hair.
