This study found that combining herbal extracts with PRP increased human dermal papilla cell proliferation via ERK and Akt protein regulation, suggesting its potential for developing hair growth therapies.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

In this study, hair follicle stem cells from ND-GFP transgenic mice were observed to be pluripotent, effectively repairing peripheral nerve and spinal cord injuries in mouse models.

This study found that BMP6 and Wnt10b competitively regulate the transition between hair follicle growth phases, offering new insights into hair follicle cycling and potential hair loss treatments.

This study found that in mouse skin, the activation of stem/progenitor cells is synchronized across different niches during growth, with the glutamate transporter SLC1A3 playing a crucial role in this process.

This review discusses various biologics for hair aging but reports no agent capable of reversing the natural aging process of hair.

This review discusses the role of stem cells in alopecia pathogenesis, highlighting the differences between scarring and nonscarring types, and reports no new clinical results.

This article reviews the molecular interactions involved in hair follicle cycling and highlights the role of dermal papilla cells, but it presents no new research findings.

This study found that high levels of parathyroid hormone-related protein expression can result in the production of shorter hair shafts, likely through effects on angiogenesis.

This review discusses the historical development and current challenges in in vitro hair follicle culture, highlighting a need for advanced models using cell lines and tissue engineering, and reports no new results.

The document concludes that managing hirsutism involves identifying the cause, using a scoring system for severity, combining cosmetic and medical treatments, encouraging weight loss, and providing psychological support, while noting the need for more research on drug treatments.

Most hair loss in children is caused by a few common conditions, and it's important to diagnose these properly and support the child's mental health.

This study found that Wnt/β‐catenin signaling influences the hair follicle regeneration process by prompting quiescent stem cells to enter the cell cycle and is necessary for maintaining the stem cell pool.

Eating isoflavone can help mice grow hair by increasing a growth factor.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

In this study of postpartum alopecia, most patients experienced significant hair regrowth within four to six months, and heredity did not appear to be a significant factor in hair loss.

This study found that dermal papilla cells cultured in vitro can promote hair follicle regeneration and maintain hair growth, with stronger ET-1 and SCF expression enhancing this regenerative ability.

This study suggests that skin sections from 4-week-old C3H mice could serve as an in vitro model for human androgenic alopecia, as minoxidil partially reverses suppressed hair follicle elongation.

This review discusses the latest understanding of androgenetic alopecia, including stem cell niches in hair follicles, and highlights emerging treatments like growth factors and platelet-rich plasma without new clinical findings.

This study found that Hoxc13 gene expression, influenced by melatonin, was associated with hair follicle activity in Cashmere goats, with in vitro evidence suggesting effects on genes relevant to follicle development.

This research found that spontaneous and depilation-induced hair growth result in biologically distinct telogen phases in murine skin, with variations in thickness, pigment content, and hair follicle composition.

This review discusses the use of laser and flashlamp technology for unwanted hair removal and reports no new clinical results, highlighting challenges with light-colored hair and treatment safety for darker skin tones.

This study found that in male androgenetic alopecia, the contrast enhanced phototrichogram technique was superior in detecting changes in hair density and thickness compared to other methods.

In this noninferiority study, researchers found that a 0.2% caffeine-based topical liquid was not less effective than 5% minoxidil solution in improving hair growth in men with androgenetic alopecia over six months.

This review discusses age-related changes in scalp skin and their potential effects on hair follicle aging, but reports no new clinical results, calling for further investigation.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This study found that the season of the year does not significantly affect the hair regrowth rate or the telogen: anagen ratio in indoor-housed Labrador retrievers.

This study found that using a ruby laser for hair removal resulted in a significant average reduction of 56.4% in hair density among participants dissatisfied with other methods.

This study reports that the novel small molecule IM176OUT05, by modifying stem cell metabolism, promoted hair regrowth and increased hair follicle numbers in mice.
