Biotin for hair growth

Read on to see how you can use biotin to increase your hair growth, improve your hair texture and improve the appearance of your skin.

Biotin, sometimes referred to as Vitamin H or B7, is one of the eight vitamins in the Vitamin B complex. This group of vitamins is particularly good for promoting health in the nervous system, the skin, eyes, liver and the hair.

You probably have sufficient biotin in your diet to keep yourself healthy. However, high stress levels, intense exercise and working long hours can all deplete your B vitamin levels.

Many hair products contain biotin due to its benefits to the hair and scalp. These products include shampoos, conditioners and split-end prevention products. However there are mixed opinions on the effectiveness of such products because very little of the biotin is likely to be absorbed and used for hair growth compared with biotin attained through diet.

Its has to be noted that generally supplements and indeed biotin from food have much more success being administered internally as opposed to externally in the problem area, in this case the scalp when treating hair loss.

How does biotin promote hair growth and hair health?

Biotin has rejuvenation properties that aid in the development of new cells. This of course is where these properties come into the curing of hair loss. Not just rejuvenating the hair itself but the scalp too, which has a critical part of reversing hair loss. Although the hair treatments that are taken externally target these problem areas, as with any treatment internal consumption of Biotin is a more effective treatment.

Biotin helps your body feed your hair

It’s the one vitamin in the body that acts on protein that is consumed to break it down into smaller chains of protein.


Hair is made of keratin, which is a form of protein made from many amino acids. Biotin is used by the body to break down proteins you consume through diet into the amino acids needed to form keratin.

Biotin is highly important as it is required for cellular growth as well as the production of fatty acids. It is also responsible for the metabolism for amino acids and fats. This role in cellular growth is one reason why biotin supplementation may be an effective element in the treatment of hair loss.

Biotin can restore hair color

Taking up to 500Mg has been known to reverse hair greying. Although this is often associated with age there are many other factors that can cause grey hair. This is where biotin has many applications for hair improvement as it has a major role in cellular growth.
