In this study, researchers identified a specific DNA aptamer, Ap.OR2AT4.17, that effectively prolonged hair growth and increased hair shaft elongation in organ-cultured human hair follicles by targeting the olfactory receptor OR2AT4. This finding suggests the aptamer's potential as a novel therapy for hair loss disorders.

This review explores the potential role of caveolin-1 in cicatricial alopecia, particularly frontal fibrosing alopecia, and discusses possibilities for targeted therapies without providing new research results.

This ex vivo study reported that melatonin significantly improved certain aging biomarkers in aged human skin, including reduced mTORC1 activity, increased fibrillin-1, and enhanced collagen and elastic fiber organization, though other key biomarkers remained unchanged.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This study found that a novel drinkable supplement significantly increased hair density and reduced hair shedding over six months in women with telogen effluvium, although the authors emphasize the need for larger, placebo-controlled trials to confirm these promising results.
