This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

This study found that GPC1 is a crucial regulator of angiogenesis in human dermal microvascular endothelial cells, indicating its potential as a target for treating alopecia.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

Among in vitro and in vivo models, this study found that Miscanthus sinensis var. purpurascens flower extract may promote hair growth, potentially by modulating growth factor expressions and facilitating earlier hair follicle transitions in treated mice.

This study found that men with androgenetic alopecia had significantly higher plasma leptin levels, which were associated with an increased risk of developing the condition.

This article discusses the concept of telogen effluvium, introduced in 1961, characterized by diffuse scalp hair loss due to various triggers, and reports no new clinical findings.

This study suggests that dermal fibroblast-conditioned medium containing multi-peptide factors may stimulate hair growth by enhancing growth factor expression and β-catenin regulation in hair follicle cells.

This study found that inhibiting 11β-HSD1 can partially reverse the negative impact of glucocorticoids on dermal papilla cells in human scalps, suggesting potential for treating stress-related hair loss.

This study found that applying a formulation derived from Bacopa procumbens significantly promoted hair growth, pigmentation, and follicular cycle acceleration in mice compared to minoxidil, potentially offering a new therapeutic approach for hair health.

In three patients with diabetic ulcers, this study reported remarkable wound healing and tissue regeneration after 3 to 6 weekly applications of growth factors-rich plasma and membrane treatment.

This study found that FZD2 is crucial for hair follicle formation and postnatal growth in mice and has a novel role in regulating early epidermal development, including stratification and cornification.

This article reviews the pathophysiology and causes of androgen-mediated hair growth in hirsutism but does not report any clinical outcomes; treatment aspects are discussed separately.

This study concluded that in female pattern hair loss patients, CGF and i-PRF treatments were more effective than PRP in increasing target area hair count, with i-PRF having the lowest adverse event rate.

In this study, injections of PRP and MZT products significantly improved hair thickness, density, and count in AGA patients over six months, with variability observed in the extent of improvement between different formulations.

In this study, researchers found that while applying a lotion containing Lactiplantibacillus plantarum subsp. plantarum N793 did not improve hair density overall compared to placebo, it was effective in improving hair density among individuals with relatively mild hair thinning.

In this randomized controlled trial, researchers found that Cellcurin therapy significantly increased hair density, terminal hair, and vellus hair counts in men and women with androgenetic alopecia, compared to minoxidil control, over 12 weeks.

Combining microneedling with platelet-rich plasma enhances skin repair and collagen production but may not offer significant extra benefits.

This study reported that using a shampoo and tonic containing horse placental growth factor improved hair thickness and density in postpartum women over three months.

This study found that Avicennia marina extract and its active compound avicequinone C inhibit enzymes and receptors related to androgenic alopecia, potentially supporting hair growth in cultured dermal papilla cells.

This study found that iontophoresis with growth factor cocktail including fibroblast growth factor 5-short significantly increased hair density in patients with androgenetic alopecia over 24 weeks.

In this study, FOL-026, a peptide based on osteopontin, was shown to promote angiogenesis and stimulate vascular cell proliferation and migration through neuropilin-1, similar to VEGF, suggesting potential therapeutic applications in vascular repair and angiogenesis-related conditions.

This study found that human hair follicle-derived mesenchymal stem cells maintained their proliferation and differentiation potential when cultured with acidic fibroblast growth factor, basic fibroblast growth factor, or epidermal growth factor.

This study suggests that FGF-9 treatment may improve cardiac function by reducing vascular apoptosis and enhancing angiogenesis in infarcted hearts of both nondiabetic and diabetic mice.

This study found no evidence that HDGF expression transforms melanocytes into tumors in a mouse model, although it may play a role in cell differentiation and tumor progression.

This study found that activating TRPV4 in the skin of mice induced hair follicle regeneration by promoting anagen transition, suggesting potential treatment strategies for hair loss.

This review discusses current pharmacological and non-pharmacological treatment strategies for PCOS, emphasizing the need for a personalized, multimodal approach due to incomplete understanding of the syndrome's pathogenesis.

This review discusses the definition of polycystic ovary syndrome proposed by the AE-PCOS Society Task Force, emphasizing hyperandrogenism, ovarian dysfunction, and excluding related disorders, while noting potential variations needing more research.

This study found that lifestyle interventions improved body composition, hyperandrogenism, and insulin resistance in women with PCOS, but did not affect glucose tolerance, lipid profiles, or clinical reproductive outcomes.
