The truth about biotin and hair growth
Biotin is an essential vitamin that’s vital for healthy skin, hair, and nails. Get all the facts here.

Biotin is essential for healthy hair. It’s in many hair loss supplements and even shampoos and other products. For the most part, people take it on its own in capsule or soft-gel form. So does this magic pill really work? 
It has advocates in the beauty industry, and healthcare providers also recommend taking biotin as a supplement. Although there are relatively few scientific studies on the effect of biotin on hair growth, there are thousands of personal testimonies of men and women who found biotin to be a hair-saver.
What is biotin and how does it help hair growth?
Biotin belongs to the B vitamin family. It takes part in a number of physiological processes in the body, and specifically, plays a key role in cell growth and protein synthesis. One of the most vital proteins for strong, full hair is keratin. It is well established that biotin strengthens hair shafts, stops thinning hair, and restores texture. 
Apart from hair, biotin also protects and rejuvenates the skin. It helps with scalp dryness, so it effectively prevents hair splitting and broken follicles.
Where is biotin found?
Biotin is found naturally in foods like nuts, various vegetables, seeds, grains, dairy products and eggs. Although eggs are an excellent source of biotin, a diet high in raw egg whites may lead to biotin deficiency because of an interference with biotin absorption. 
Because biotin is a water-soluble vitamin, it doesn’t accumulate in the body, so there is a possibility that with an unstable, unbalanced diet, a person could potentially develop biotin deficiency.
Biotin deficiency is rare, and is usually caused by genetic factors. However, there is also evidence that some antibiotics and epilepsy drugs may lower biotin absorption. Symptoms include skin rash around the mouth, brittle hair, and hair loss. 
What does science say about biotin and hair growth?
According to a recent study , 38% of women (who sought help for hair loss) had biotin values consistent with biotin deficiency (<100 ng/L). This shows that biotin deficiency may not be as rare as previously thought, and biotin levels are most likely affected by many factors like anorexia, smoking, alcoholism, pregnancy, and age. 
Judging by this evidence, it seems biotin is a viable option for those seeking help with hair thinning and loss. But, hair loss isn’t that simple. Biotin can be hit or miss, and the more time that goes by, and the more hair is lost down the drain, the harder it will be to recover. 
Research on biotin on its own is not fully conclusive, though all the studies that have been performed have not shown any negative effects.
Is biotin enough to treat hair thinning and loss?
Biotin supplements are very popular, but hair loss is usually caused by multiple factors. Pinpointing the exact issue can be a problem, which is why regimens like TRX2® hit hair loss from multiple angles. Our experienced Oxford Biolabs® scientists worked out the best possible intake and ratio of ingredients based on credible science. One can’t just purchase all the ingredients separately and expect the same results. 
Biotin is just one component of TRX2® , which also includes several proven ingredients that have all been shown to support and maintain normal hair: zinc, selenium and niacin. It is, though, the first supplement to contain potassium chloride, L-carnitine-L-tartrate and BCAA, delivered via a proprietary potassium channel-stimulating complex.
