A Novel Cosmetic Anti-Hair Loss Approach: An Extract of Leontopodium Alpinum Inhibits Catagen Development

This study suggests that edelweiss extract may promote hair growth and reduce shedding in ex vivo experiments by affecting hair follicle anagen phase duration and keratinocyte proliferation.

This study reported that a treatment serum containing ingredient blends with panthenol, licorice extract, and red clover extract significantly improved hair volume, scalp coverage, and reduced hair breakage over 6 months in individuals with thinning or damaged hair.

This study demonstrated that engineered skin substitutes using human keratinocytes and murine dermal papilla cells can develop pigmented hairs without sebaceous glands, suggesting separate pathways for hair development and eruption.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

This study developed a method for expanding human dermal papilla cells in vitro while maintaining their ability to induce hair growth, advancing the potential for follicular cell implantation as a treatment for hair loss.

This study observed that vitamin D receptor expression in certain hair follicle cells varies throughout the murine hair cycle, suggesting a potential role for 1,25-dihydroxyvitamin D3 in hair follicle biology.

This article discusses the role of androgens in hair follicle changes, explaining how dihydrotestosterone contributes to hair thinning on the scalp, while promoting thicker facial hair in men, and reports no new clinical results.

This article reviews the role of androgen in male pattern hair loss and its impact on hair follicle miniaturization, but it does not present new research findings.
