In this study, 0.5% timosaponin BII from Anemarrhena asphodeloides promoted hair growth in C57BL/6 male mice, showing effects comparable to 2% minoxidil.

This study found that low concentrations of CBD promoted hair follicle growth, while higher concentrations induced hair follicle regression and increased cell death in an experimental setting.

This study found that orally administering the CCR5 inhibitor Maraviroc improved hair loss in 4 out of 5 mice with alopecia areata and also reduced the development of the condition, evidenced by decreased CCR5+ T-cell infiltration in treated mice.

This study reports that the loss of Langerhans cells in lichen planopilaris scars may be linked to the downregulation of ITG αvβ6, which is not seen in other scar formation diseases.

This study suggests that the outer root sheath of human hair follicles may act as a "metabolic center," capable of synthesizing glucose from lactate, which supports glycogen metabolism.

This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.

This study reported that using platelet-rich plasma as an intraoperative holding solution significantly improved hair density and follicular growth in hair restoration surgery for androgenetic alopecia.

In this study, women with chronic telogen effluvium experienced reduced hair shedding after being treated with once daily oral minoxidil for 12 months, but facial hypertrichosis was a reported side effect, suggesting the need for further placebo-controlled research.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This study found that a single injection of platelet-rich stroma significantly increased hair density in men with androgenetic alopecia within 6 to 12 weeks, with no reported side effects.

This review analyzed clinical trial protocols for platelet-rich plasma preparation in hair loss treatment, finding inconsistent and insufficient reporting that complicates comparison and efficacy determination.

This review discusses the use of platelet-rich plasma for facial rejuvenation, acne scarring, and androgenic alopecia and reports positive outcomes but emphasizes the need for standardized preparation and application methods.

This review outlines the current state of freeze-dried platelet-rich plasma (FD-PRP) research, emphasizing its use in wound healing, lumbar fusion, knee conditions, and dentistry, but reports no new clinical findings.

This study found that platelet lysate produced higher follicular regeneration in hair restoration surgeries compared to activated PRP and saline, with significant gains in both follicular unit and hair density.

This study found that platelet-rich plasma was effective for hair regrowth in women with androgenic alopecia, though less so than minoxidil, but it was associated with improved quality of life responses.

This study found that trichoscopy aided in assessing treatment responses for patchy alopecia areata, with both intralesional corticosteroids and platelet-rich plasma showing effectiveness, but only PRP significantly improved patient symptom impact scores.

This study observed that Cyp27b1−/− mice exhibited growth and skeletal abnormalities similar to those of Vdr−/− mice, despite differences like the development of alopecia in Vdr−/− mice, suggesting that 1α,25D3 may directly influence chondrocyte proliferation and differentiation.

In this study, minoxidil and human platelet lysate affected gene expression related to hair growth signaling pathways in mouse hair follicle cells.

This article discusses scalp tissue expansion as a superior reconstructive option for large defects over traditional skin grafts and flap methods, but reports no new clinical outcomes.

This letter reported that combining platelet-rich plasma with hair transplants did not show benefits for treating androgenetic alopecia.

PRP treatment satisfies 58% of female hair loss patients, with most noticing fuller, thicker hair and less shedding.

This study found that treating androgenetic alopecia with platelet rich plasma increased hair density and diameter while decreasing the proportion of telogen and vellus hairs.

In this study, a herbal mixture (RAA) was found to promote hair growth in mice, showing increases in hair density and follicle size similar to minoxidil treatment.

This study found that vitamin D regulates cholesterol metabolism and may influence prostate cancer development through mechanisms affecting prostate cell growth and sex hormone metabolism.

This study found that obesity in women may impair endometrial stromal function and contribute to reproductive complications, possibly due to metabolic influences rather than immune cell differences.

This study found that alopecia in captive Rhesus macaques may be linked to chronic hypersensitivity dermatitis with CD4+ cell inflammation, possibly influenced by altered housing and reduced pathogen exposure.

This study found that elastin-like recombinamer (ELR) wound dressings promote tissue regeneration and stability without rejection in ex vivo and in vivo models, indicating potential for hard-to-heal wound treatment.

In this study on a murine model, researchers observed that a 5% minoxidil solution reduced stress-induced changes in hair growth, suggesting its potential for managing stress-related hair loss in humans.

This study found that scalp hair follicles had higher expression of cytokeratin 15 and distinct hair layers compared to other body regions, highlighting differences in hair follicle characteristics.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.
