What’s Biotin?

Also known as vitamin B7 (or vitamin H), biotin is a water-soluble vitamin which naturally supports hair growth by promoting production of keratin (the main component of hair). Long story short, biotin is believed to strengthen existing strands as well as nourish growing hair follicles, improving thickness and durability in the long run.

Biotin is widely promoted as a “miraculous” hair growth solution by the hair care industry. Is it true? Is it a scam? We’ll see that the answer falls in between.

Does Biotin Work?

Yes and no. Let’s be as clear as possible. While biotin supplements has proven benefits in people with biotin deficiencies, it is not proven to have any effect on healthy people. In other words, biotin can both promote hair growth and prevent hair loss only in persons affected by a biotin deficiency. Because thinning hair and hair loss are common symptoms of biotin deficiency, biotin supplements are wrongly considered as universal hair growth boosters. Biotin supplements exist in “fun” edible form, like gummies. If taken excessively, they are not always safe.

On the other hand, a 2013 study found that a biotin shampoo and conditioner improved hair volume and thickness in women. The study involved 30 women who used the biotin shampoo and conditioner for 3 months. At the end of the study, the women had a significant increase in hair volume and thickness compared to the baseline measurements. It’s worth noting that while this study suggests that biotin may be beneficial for hair health, more research is needed to confirm these findings and determine optimal dosages and treatment durations.

If you still want to try biotin, instead of eating it like candies, try adding it to your hair cleansing routine with a vegan biotin shampoo.
