In this study, a single deslorelin acetate implant led to substantial and sustained hair regrowth in two sexually intact male keeshonden with hair cycle arrest.

This review of murine studies reports that γ-rays affect hair follicle pigmentation in mice throughout the hair cycle, while effects on hair structure may be obscured by aging.

In this study, researchers found that pregnant mice exposed to excessive androgen led to thinner ventricular walls and cardiac hypertrophy in offspring, suggesting that prenatal androgen exposure adversely affects cardiac health through reduced cardiomyocyte proliferation.

This study found that Pomeranian dogs with a woolly coat type and male dogs had a higher risk of developing Alopecia X in the Netherlands and Belgian regions studied.

In this study, kartogenin promoted hair growth by enhancing cell proliferation and migration in vitro and extended hair length in mice, suggesting its potential as a treatment for hair loss.

In this study, researchers observed that in nude mice, exogenous stimulations lengthened the hair-existing phase and shortened the no-hair phase, with minoxidil influencing male and female mice differently.

This study observed that alkaline phosphatase activity in dog hair follicles varied with hair cycle stages, displaying weak to negative reactions in the anagen stage, positive reactions in catagen, and strong positivity in telogen.

The Naked gene in mice causes abnormal sebaceous glands and disrupts hair follicle organization.

This study reveals that the microRNA-200 family, highly enriched in hair matrix progenitors, restricts sebaceous gland development by inhibiting the SOX9-dependent lipogenic program, highlighting its specific role in epithelial plasticity within hair follicles.

This study found that supplementing Liaoning cashmere goats with HMBi increased cashmere length while decreasing its diameter, attributed to changes in Met-related metabolites and elevated expression of genes related to the Met cycle and cell differentiation pathways such as Wnt and MAPK.

Pigs are a good model for studying human hair growth and disorders.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

MPZL3 protein affects hair growth cycles and could help manage hair loss.

This study found that laser hair removal results in females were not influenced by hormonal fluctuations during different menstrual cycle phases, although pain tolerance was slightly lower during menstruation without reaching statistical significance.

In this study, researchers implemented a recommendation algorithm using Melia dubia liquid and fermented rice water to improve nutritional suggestions for women experiencing menstrual issues, achieving an accuracy of 94% in detecting nutritional needs during menstrual cycles.

This study found that ALRN-6924, a clinical-stage dual inhibitor, can selectively protect human scalp hair follicles from paclitaxel-induced toxicity and damage by inducing transient cell cycle arrest in healthy cells without affecting cancer cells, potentially reducing chemotherapy-induced alopecia.

In this study, Fgf20 was found to trigger movement and morphogenesis in dermal fibroblasts, facilitating dermal condensate formation essential for hair follicle development.

This opinion from the EFSA Panel concludes that the health claim regarding spermidine prolonging the anagen phase of the hair cycle does not meet regulatory criteria as it is related to disease treatment.

This study suggests that the regulation of GABA‐A δ subunit expression by ovarian progesterone-derived neurosteroids may influence seizure susceptibility in catamenial epilepsy.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This study observed distinct sex differences in hair growth cycles and regeneration in C3H/He mice, noting that females regenerated hair faster after adhesive material application, whereas males were more reliant on macrophage activity for this process.

This study found that the carbohydrate-based excipient β-cyclodextrin forms a stable inclusion complex with the active ingredient of Minoxicapil®, potentially enhancing its formulation for hair-loss treatment, and in vitro assays suggest improved proliferation of DPC cells, supporting its use in topical treatments.

This study found that the GPRC6A-Duox1 signaling pathway influences hair cycle progression and testosterone-mediated hair loss in mice, suggesting that disruption of this pathway leads to resistance against testosterone-induced hair loss and longer anagen phase duration.

This study found that perifollicular vascularization around the dermal papilla adjusts dynamically to physiological changes, with minoxidil enhancing vessel mobilization and aging processes inhibiting it, highlighting potential targets for treating hair loss and skin aging.

This case study describes a 70-year-old woman with a congenital skin condition, nevus sebaceus, who underwent hair transplantation which maintained hair growth for about 40 years; however, secondary tumors developed over time, highlighting the persistence of tumorigenic potential within nevus sebaceus.

This clinical study found that Rosmarinum officinalis mother tincture significantly improved hair volume and density in individuals with diffuse hair loss by enhancing hair parameters measured through a hair shedding visual scale and ponytail thickness test.

In this study, porcine collagen acellular dermal matrix scaffolds combined with mice platelet-rich plasma were associated with increased hair density and follicle regeneration in mice with alopecia, suggesting a potential therapeutic approach.

This study mapped a detailed genetic profile of goat hair follicle apoptosis, identifying key genes and regulatory factors involved in the hair cycle, offering new insights into programmed cell death.
