December 1969 in “The Lancet” This study found a significant shift to the telogen phase in the hair growth of children with classical marasmus compared to normal children, suggesting a connection to the chronicity of the condition.
March 2026 in “Current Bioactive Compounds” In a rat model, this study observed that applying high-concentration (100%) P. europaea root extract topically significantly enhanced hair growth by increasing the number of hair follicles, hair shaft diameter, and hair length compared to controls, suggesting its potential as a treatment for alopecia.
June 2026 in “Frontiers in Cell and Developmental Biology” In this study, researchers used single-cell RNA sequencing to map the hair follicle microenvironment in fine-wool sheep, identifying specific cell types and gene expressions that influence wool fiber diameter, with dermal papilla cells playing a significant role in hair follicle development.

August 2022 in “Molecules/Molecules online/Molecules annual” This study found that microbial adenosine and biotin treatments derived from Staphylococcus epidermidis Cicaria culture may help inhibit hair loss by maintaining the hair's growth phase.
