July 2021 in “Indian journal of dermatopathology and diagnostic dermatology” In this study, researchers documented several trichoscopic features that were statistically significant indicators of alopecia and scalp disorders compared to healthy controls.
January 2021 in “Global Dermatology” This study involved selecting patients with specific types of alopecia for treatment but does not report clinical outcomes.
Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.
September 2019 in “IP Indian journal of clinical and experimental dermatology” This study reported that in women with pattern baldness, hormonal levels and iron deficiency were significantly associated with the condition, but trichoscopic findings were similar across different forms of female pattern hair loss.
August 2019 in “Research Square (Research Square)” This study found that exposure to red LED light may improve fibre quality and hair follicle development in Angora rabbits, potentially due to increased melatonin secretion.
April 2019 in “The journal of investigative dermatology/Journal of investigative dermatology” This study in mice suggests that defects in hair follicles with mesenchymal TSC2 disruption may result from an impaired TGFβ1 response, indicating a potential novel treatment approach for tuberous sclerosis complex.
September 2018 in “PubMed” This review discusses the aging-related changes in hair properties, their impact on styling, and potential interventions, without providing new clinical results.
April 2018 in “Journal of Investigative Dermatology” In this study, researchers reported that IL-17C plays a key pro-inflammatory role in human skin diseases and may be a promising therapeutic target for inflammatory skin conditions.
September 2017 in “Journal of Clinical Dermatology” This study found that applying a growth factor cocktail including FGF9 with microneedling significantly increased hair density and diameter in patients with androgenetic alopecia, with similar results regardless of microneedle depths between 0.5 mm and 0.8 mm.
