From Gut to Follicle: New Trial Links Microbiome to Hair Density

The clinical study on Biotical™ GH adds meaningful evidence to the emerging science of the gut–hair axis. By running a 24-week, randomized, placebo-controlled trial, researchers were able to show not just improvements in hair density, but also measurable shifts in the scalp microbiome. This is important because the scalp environment plays a critical role in follicle strength, barrier integrity, and the inflammatory status of hair roots. The fact that supplementation increased protective species like Staphylococcus hominis—while reducing pro-inflammatory microbes such as Cutibacterium kroppenstedtii—suggests a dual mechanism: systemic modulation via the gut microbiome and local improvements at the follicular level.
