Biotin for hair growth and thickness: fact or myth?

As an avid shopper and researcher - I consider myself an expert - in everything related to the health of the body, skin, and hair, I have always been interested in the idea of nutritional supplements, their importance, their life cycle within the body, and then our lives when using them - do we use them continuously, intermittently, or do we not use them at all and are satisfied with only proper nutrition, exercise, and breathing clean air?


Did I look at you?


I think I can break the boredom of talking by telling you what happened yesterday when I was browsing some stores that I trust and always get my personal care supplies from. I noticed a new product and it passed before my eyes more than once in more than one product. Biotin (Vitamin B7) you may have heard a lot about it, but here is a new trend in its use, especially with the enthusiastic aura around it, the number of studies that have been conducted on it, and real experiments that have actually been conducted by regular users that say that its results are amazing in hair growth and thickness.


A fat-soluble B vitamin, biotin is one of the most important active ingredients in many hair-proven products. Shampoos, conditioners, and creams that promise thicker, fuller hair often contain biotin.


Likewise, taking biotin as a supplement plays an effective and central role in solving the problem of excessive hair loss, bald spots, and achieving the natural thickness of your hair.


This article guides you through a simple and informative journey to explore the magical link between biotin and your hair's shine, answering the big question: Is it a safe and effective solution for hair growth and protection from hair loss?


Biotin supplements are likely to prevent hair loss and promote hair growth in people with biotin deficiency.


In one study, biotin deficiency was found in 38% of women with hair loss. Of these participants, 11% had a history of deficiency risk factors, such as inflammatory bowel disease (IBD) or use of certain medications such as antibiotics (5Trusted Source).


While this study did not evaluate the effects of biotin supplements or biotin-enriched hair products on preventing hair loss, it does illustrate the relationship between hair loss and insufficient biotin levels.


Other causes of hair loss include:

  • Androgenetic alopecia, also known as female pattern baldness
  • rapid weight loss
  • Other nutritional deficiencies such as iron, zinc, and protein
  • Some hormonal diseases such as thyroid disorder


So, even if it is proven that biotin is the main cause of hair loss, it is important to consult a doctor to determine whether there are other contributing factors or not. This will avoid wasting time on one treatment option while ignoring others, and will ensure effective results for thick, strong hair.


While for people who do not suffer from biotin deficiency, there is no strong evidence to support the use of biotin for hair growth or to prevent hair loss.

Since hair thinning and poor hair growth are sometimes linked to biotin deficiency, correcting the deficiency can help restore hair growth in some people.


There are several other factors that can also cause hair loss and thinning, including deficiencies in other nutrients such as iron and zinc.


Finally, if you plan to take biotin supplements, tell your doctor before having any blood tests because the vitamin can interfere with some lab test results.
