This study found that latanoprost induces significant growth and pigmentation of lashes and ancillary hairs, with effects mirroring both brief and chronic treatments observed in patients and animal models.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.

This review summarizes the major events and regulators of the hair cycle in mammals but reports no new experimental results; it emphasizes the complex regulation of stem cell activation and differentiation during hair growth.

Hair loss that spreads out can often fix itself or be treated by finding and handling the cause.

This study found that using a low-level laser comb led to hair regrowth in a mouse model of alopecia areata, while sham-treated mice showed no hair regrowth.

This review discusses the physiological skin changes during pregnancy and reports no new clinical results, emphasizing the importance of distinguishing these changes from pathological conditions.

This review discusses the safety and efficacy of bimatoprost ophthalmic solution 0.03% for enhancing eyelash growth by influencing the eyelash hair cycle and follicles, and it reports no new results.

The study reports that Fgf18 and Tgf-β2 signaling pathways in hair follicle stem cells have opposing effects on the timing of hair cycle transitions, influencing the shift from telogen to anagen phases.

This review discusses the enhanced understanding of how stem cell niches respond adaptively to systemic signals, aging, and local perturbations, but reports no new research findings.

This study found that women with common baldness treated with cyclical antiandrogen therapy for 52 weeks experienced increased hair density and a higher percentage of hairs in the anagen growth phase.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

This review discusses the cutaneous application of bimatoprost ophthalmic solution 0.03% for enhancing upper eyelash growth and suggests it is both safe and effective; no new clinical results are reported.

This study found that 655-nm red light with LED enhanced hair shaft elongation and reduced catagen transition in human hair follicles in vitro by activating the Wnt/ß-catenin signaling pathway.

In this study, topical application of α-methylspermidine during the telogen phase in mice induced hair growth by increasing the polyamine pool and mimicking the anagen phase's characteristics.

This review discusses "follicular hypoglycania" as a potential pathology in hair growth disorders and reports that proteoglycan replacement therapy may improve hair loss treatments, though it presents no new clinical trial results.

This study found that Sox10 may play a role in early hair follicle development and cycling, as it is expressed in specific regions of the hair follicle during different phases of the hair cycle in mice.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

The document concludes that hair biology is complex and there are still unanswered questions about hair loss and follicle changes.

This study reported that combined oral finasteride and topical 5% minoxidil treatment in men with male-pattern hair loss improved hair growth by initiating anagen in pre-existing but deficient follicles, yet the growth rates remained unchanged and did not normalize hair productivity.

This study found that deer antler aqueous extract may promote hair growth in mice by extending the anagen phase and increasing cell proliferation in the hair follicle region.

This study demonstrated that keratin extract can stimulate hair growth by inducing the anagen phase in telogenic mice.

This study found that topical application of partial proteasomal inhibitors accelerates hair growth by stabilizing β-catenin and disrupting the hair cycle's normal balance of activation and quiescence.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

This review discusses techniques for harvesting follicular units, medical treatments for androgenetic alopecia, and potential future advancements in hair restoration therapy, but it reports no new clinical results.

This systematic review concludes that exosomes may offer significant therapeutic potential for treating androgenetic alopecia, with observed improvements in hair density and follicular health, but further long-term clinical studies are necessary for validation.

In this study, 14 sessions of 675 nm laser stimulation significantly improved hair count, density, and thickness in Indian patients with androgenetic alopecia, with an increase of around 17% in hair parameters over four months.

This study reported that the pseudoceramide bis-oleamido isopropyl alcohol (BOI) promotes hair growth in ex vivo cultured human hair follicles, likely by enhancing sphingolipid synthesis in dermal papilla cells.

This article reviews the history, biology, genetics, prevention, conventional treatments, and herbal alternatives for hair loss, but reports no new research findings.

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.
