Exosomes in trichology: A literature review

Exosome therapy is a promising, minimally invasive approach for AGA, AA, and CIA, supported by robust preclinical biology but preliminary and heterogeneous clinical data. Progress to routine practice will require adequately powered, multicenter randomized trials with standardized outcomes, along with harmonized manufacturing and regulatory frameworks (GMP-compliant production, batch-level quality control) to ensure reproducibility and safety.
