# They Tested It: Which Shampoo Truly Boosts Hair Growth? When it comes to hair health, one question echoes louder than ever: Which shampoo genuinely boosts hair growth? With countless labels promising miracles, finding a proven, effective formula can feel like searching for a needle in a database. But what if the answer isn’t a magical elixir—but a scientifically tested shampoo backed by clinical evidence? In this in-depth review, we test popular hair growth shampoos to identify which ones deliver real, measurable results. ## Why Shampoo Matters for Hair Growth Before diving into the tested brands, it’s important to understand that “hair growth” shampoos work differently. True growth enhancers often contain active ingredients likebiotin, minoxidil (in low concentrations), ketoconazole, caffeine, or plant extracts such as saw palmetto and green tea. These ingredients support scalp health, reduce hormonal miniaturization, stabilize follicles, and stimulate circulation—key factors for promoting new hair.
