do Biotin Shampoos Actually Work? Dermatologists Weigh in

Key Takeaways

* While biotin shampoos may help make hair feel thicker, there’s no solid evidence they actually boost hair growth or strength in those without a deficiency.

Biotin has been a sought-after ingredient in the beauty world for years now, especially when promoted as a means for improving hair health. It’s often touted as a miracle supplement that increases hair’s shine and volume while strengthening hair follicles and preventing loss. Typically, it’s taken as an oral supplement but, it is also a key ingredient in popular biotin shampoos. Curious about whether biotin shampoos actually work, we reached out to dermatologists for some answers.

what Is Biotin?

Biotin is a common over-the-counter supplement,also known as vitamin B7. It plays a critical role in a handful of metabolic processes in our body. More specifically, it stimulates keratin growth which is responsible for healthy hair, nails, and skin.

Most of our biotin intake comes from what we eat, as it can be found naturally in many foods including eggs, fish, bananas, avocados, broccoli, and legumes.[1]

Biotin as a Supplement

Biotin can be taken on its own in pill form, or as an ingredient in a daily vitamin.

Does Biotin Shampoo Actually Help hair Growth?

Biotin shampoo is everywhere. From drugstore shelves to online retailers, it’s marketed as a solution for thinning hair and a boost for overall hair health. But does it actually work? The answer, unfortunately, is complicated. While biotin is essential for healthy hair, skin, and nails, simply washing your hair with a biotin-infused shampoo isn’t a guaranteed path to a fuller head of hair.

What is Biotin?

Biotin, also known as vitamin B7, is a water-soluble vitamin that plays a crucial role in converting food into energy.It’s also involved in the metabolism of fatty acids, amino acids, and glucose. A biotin deficiency can lead to hair loss, brittle nails, and skin rashes, but these deficiencies are rare in people who eat a balanced diet.

Why the Popularity of Biotin Shampoo?

The surge in popularity of biotin shampoo stems from the understanding that biotin is importent for hair health. Marketing often emphasizes this connection, leading consumers to believe that applying biotin directly to the scalp will stimulate hair growth. However, the science doesn’t quite back this up for most people.

The Limitations of Biotin Shampoo

It’s also worth noting that these shampoos are left on the scalp only briefly and then rinsed away, so the skin probably won’t have sufficient time to absorb the ingredients and work at a follicle level. That doesn’t mean they’re not worth using-they may make your already existing strands feel thicker and healthier, just don’t expect a miracle.

Are There Better options for Hair Growth?

The reality is that we just don’t have any compelling scientific data to support using biotin shampoo for hair growth or improved strength in healthy individuals.

Until research proves one way or another, you may be better off using volumizing hair products that temporarily promote a fuller-looking head of hair and utilizing oral or topical treatments that have a more robust scientific track record of delivering long-term results.
