June 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This narrative review from the authors discusses mechanical scalp stimulation as a potential treatment for androgenetic alopecia, suggesting it has a biologically plausible mechanism but immature clinical evidence; marketing of these devices currently outpaces their supporting data, indicating a need for better-controlled trials.
June 2026 in “Zenodo (CERN European Organization for Nuclear Research)” This narrative review suggests that while mechanical scalp stimulation has a plausible mechanism for aiding androgenetic alopecia, its clinical evidence is insufficient, and the marketing of stimulation devices currently outpaces their efficacy data.
