This study suggests that D-panthenol may promote hair growth by enhancing cell viability, suppressing apoptosis markers, and elongating the anagen phase in human hair follicle cells.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

This study found that transient non-lethal levels of endogenous ROS in cultured human hair follicles promoted entry into the growth phase by activating the hair follicle stem cell niche.

In this study, researchers observed that activated platelet-rich plasma promoted hair growth in mice and increased cell proliferation in vitro, suggesting potential clinical applications for hair growth treatment.

This study suggests that new cells are incorporated into the dermal papilla during the early anagen phase of the hair cycle, which may influence hair growth consistency and follicle size changes.

This study found that human hematopoietic mesenchymal stem cells increased the viability and migration of human outer root sheath cells in an in vitro alopecia areata model, involving Wnt/β-catenin and JAK/STAT pathways.

This review discusses the potential of evaluating hair follicle characteristics as early indicators of vascular impairment and organ damage in pre-diabetic individuals, but reports no new clinical results.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study found that platelet lysate significantly improved hair growth and follicle performance in both experimental settings and AGA patients, showing results comparable to platelet-rich plasma.

This study suggests that the epigenetic marker 5-hmC may dynamically influence hair follicle bulge activation during anagen growth in mice, warranting further investigation into its role in stem cell regulation.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

In this study, rat vibrissa follicles transplanted into mice demonstrated survival, partial sympathetic nerve reinnervation, and increased norepinephrine levels 37 days post-implantation, suggesting potential for hair growth despite not returning to normal nerve function.

This study suggests that keratin 15 and Id3 proteins play distinct roles in epithelial and dermal cell activities during the regeneration stages of rat vibrissae hair follicles.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

This study found that the topical Shen Bai hair growing decoction may improve androgenetic alopecia in mice by suppressing TNF-α and IL-6 levels, enhancing follicle density, and reducing apoptosis.

In this study, researchers found that topical application of the diabetes medication Sitagliptin in mice accelerates hair follicle regeneration and reduces fibrosis, suggesting it could be repurposed to treat hair loss conditions like alopecia.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that a new hydrogel formulation of basic fibroblast growth factor showed promise in promoting hair regrowth and reducing inflammation in testosterone-treated mice.
