Biotin is a popular ingredient in hair care and hair loss routines—but does it actually aid in growing facial hair? While it’s not a clinically proven solution for hair loss on its own, biotin does play a key role in maintaining overall hair health. Let’s delve into how it works—and whether it can support beard growth.
What Is Biotin?
Biotin, also known as vitamin B7, is a water-soluble vitamin that helps your body metabolise proteins, fats, and carbohydrates. One of its primary functions is aiding the production of keratin, the protein that forms your hair, skin, and nails.
Although your body naturally produces small amounts of biotin, it’s not enough to meet your daily needs. That’s why it’s essential to obtain biotin through your diet or supplements.
A deficiency in biotin can result in symptoms such as brittle nails, irritated skin, and, in some cases, hair thinning or loss.
Biotin and Hair Loss: What the Research Shows
Biotin has been studied for its impact on hair health, particularly in individuals with conditions like alopecia or a biotin deficiency. In such cases, supplementation has been shown to improve hair strength and thickness.
However, if you’re not deficient in biotin, the benefits may be less pronounced. The only clinically proven treatments for male pattern hair loss remain Finasteride and Minoxidil. Even so, biotin is often included in hair care routines to support hair structure and complement other treatments.
Can Biotin Support Beard Growth?
So, does biotin help with growing a beard?
While there’s limited direct research on biotin’s effects on facial hair, the theory makes sense: if biotin supports keratin production and overall hair health, it could also benefit the hair follicles in your beard.
Some men find biotin useful as part of a broader beard care routine—particularly if they’re noticing early signs of patchiness or thinning. Biotin is also absorbable through the skin, meaning it can be included in grooming products to potentially enhance results.
That said, if your goal is to grow a fuller, thicker beard, Minoxidil remains the product with the strongest evidence behind it.
The Best Approach to Boost Beard Growth
At Sons, we recommend combining biotin supplementation with a targeted, clinically proven beard treatment—like our Beard Booster.
The Beard Booster contains 3% Minoxidil, which works by increasing blood flow to the hair follicles, stimulating growth in areas that are patchy or slow to fill in.
When used daily, most men start to see visible improvements within just three months.
Pairing it with our Hair Growth Complex, which includes biotin, helps support your body from the inside while Minoxidil works on the surface.
Final Thoughts
While biotin alone won’t regrow hair, it plays an important role in supporting hair health—making it a valuable addition to your beard growth routine.
For real, noticeable results, combining biotin with Minoxidil gives you the best chance of achieving a beard you can be proud of.
