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.

September 1989 in “Journal of The American Academy of Dermatology” This article describes cases of unusual scalp whorl patterns, including triple parietal and right temporal whorls, that were associated with normal development, and discusses theories of hair whorl development.
September 2015 in “The European physical journal. E, Soft matter and biological physics/The European physical journal. E, Soft matter” In this study, a mechanical model was developed to describe and validate the effectiveness of overnight hair curling, suggesting that combining it with hair fixatives can maintain a desired curl for over a day.

January 2015 in “International Journal of Trichology” This study suggests that mechanical stress may influence androgenic alopecia patterning through a stretch-induced and androgen-mediated mechanotransduction mechanism in dermal papilla cells.
