What the Study Found (In Plain English)
Published in The Journal of craniofacial surgery (2026), this randomized controlled trial evaluating 30 human participants investigated: Chitosan, a natural polysaccharide with immunomodulatory and regenerative properties, has shown promise in enhancing tissue repair. Key clinical takeaway: In this small controlled study, microneedling followed by topical 2% chitosan resulted in significant improvements in hair growth parameters compared with no treatment, and outcomes were generally comparable to those observed with 5% minoxidil.

Study Limitations & Caveats Before You Act
Clinical trials evaluate specific inclusion/exclusion cohorts under protocol-controlled conditions (Randomized Controlled Trial). Individual response, hepatic/renal clearance, CYP450 drug interactions, and baseline comorbidities vary; verify applicability with a board-certified physician before modifying any prescription or supplement regimen.
