It seems we’re always hearing about biotin, the ‘wonder vitamin’ which promises to prevent thinning hair and provide us with thicker, fuller locks. But what is biotin, and why is it important for hair health?
What is biotin?
Biotin is a water-soluble B vitamin (sometimes known as Vitamin H), which is known for its role in promoting healthy skin, hair and nails. It has an important role to play in the health of your hair, by stimulating growth, protecting from dryness and increasing elasticity (and thereby helping to prevent breakage).
Our bodies usually produce enough biotin and can recycle biotin we have already used, so actual biotin deficiency is very rare. The good news is that for those who are biotin deficient, the vitamin is naturally present in many foods, such as wholegrain cereals and wholewheat bread, dairy products, eggs, chicken, salmon, nuts and Swiss chard.
Biotin supplements and getting the right dose
Because biotin deficiency is quite rare, there is usually no need to take high strength biotin supplements. However, dietary supplements such as Hair Vitalics may be recommended as part of a comprehensive hair loss treatment plan in order to ensure you are getting the necessary nutrients needed for healthy hair so that any regrowth is in the best possible condition.
When it comes to biotin, men and women aged 19 and over only need around 30mcg a day – this amount can usually be consumed within the average person’s daily diet. Biotin overdose could cause more harm than good and could lead to the development of skin rashes, slower insulin release, high blood sugar levels and decreased levels of vitamin C and B6.
Can biotin help hair growth?
Whilst biotin deficiency can lead to hair loss and thinning hair, there are more likely to be other reasons behind your hair loss condition, such as stress, iron-deficiency anaemia or even a thyroid disorder.
There have been suggestions that taking biotin supplements could reduce hair loss, however this is not proven. A study carried out in 1999 showed that taking biotin supplements together with zinc and the application of synthetic steroid hormone cream could help reduce hair loss in children experiencing Alopecia Areata. However, the effect of the biotin in isolation has not been established.
What about biotin shampoos and treatments?
In recent years, a wave of biotin shampoos and hair treatment products have flooded the market, promising us thicker, fuller hair that’s stronger. These shampoos and hair treatments aren’t actually backed by scientific evidence and usually only contain trace amounts of the vitamin.
So whilst they may not do any harm to your hair, and could boost its volume (depending on the other ingredients), there is nothing to suggest that they will prevent hair loss – particularly where genetic baldness is concerned.
