June 2025 in “Cancer Management and Research” This study found that scalp cooling resulted in visible hair retention in 53% of breast cancer patients undergoing Epirubicin/Cyclophosphamide and Paclitaxel treatment, with factors like hair bulb diameter, shaft diameter, and anagen rate significantly predicting outcomes.
February 2026 in “SHILAP Revista de lepidopterología” This study demonstrated that engineered exosomes loaded with growth factors, EGF and FGF, could successfully repair the hair follicle microenvironment in an androgenetic alopecia mouse model, enhancing hair growth without causing adverse immune reactions or toxicity.
In this study, researchers found that follicular and epidermal transglutaminases are biochemically and immunologically distinct, suggesting the possibility of selectively modifying hair or epidermal proteins.
This study examined molecular predictors of ritlecitinib efficacy in treating alopecia areata, highlighting the role of JAK3-dependent inflammation and follicular integrity as important factors in understanding disease mechanisms and potential therapeutic effectiveness.
May 2026 in “Frontiers in Cell and Developmental Biology” In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.
