In the world of haircare, few ingredients have shot to fame like biotin has. A key player in energy production and keratin synthesis (the protein that forms the structure of your hair, skin and nails), biotin has quietly crept into everything from our shampoos to our hair, nails and skin supplements.
For people with normal levels of biotin, there’s little evidence that supplementing more of it will result in Rapunzel-style growth. But that doesn’t mean it’s not useful elsewhere. In fact, biotin has started to appear more and more in topical hair formulas, and it makes sense. It plays a supportive role in keratin structure, so using it in products that strengthen the strands you already have could help reduce breakage and improve the look and feel of your hair.
While it’s important to remember that no single ingredient can transform your hair overnight, formulas packed with biotin (especially when paired with hydrators, proteins and protective ingredients) can help build stronger, shinier strands over time. Below, we round up the 10 formulas the Stylist beauty team are loving for strong, shiny locks.
