This study reported that a curcumin-zinc microneedle patch improved hair regrowth and wound healing in animal models, suggesting potential as a versatile treatment for hair loss.

This study found that the synthetic retinoid EC23 effectively induces keratinocyte hyperproliferation and enhances hair growth in mice, showing more potency than all-trans retinoic acid.

This study introduces the concept of a "gut–brain–skin axis" where ingesting a specific Lactobacillus strain in mice may reduce stress-induced skin inflammation and hair growth inhibition.

In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

In this study, the researchers identified MJ04, a selective JAK3 inhibitor, as a promising candidate for promoting hair growth, demonstrating efficacy in both animal models and human hair follicle assays with a favorable safety and pharmacokinetic profile.

In this study, researchers developed a polyphenol–amino acid nanozyme capable of controlled hydrogen peroxide delivery, which effectively activated hair follicles via oxidative stress in a mouse model, suggesting a potential non-pharmacological treatment for alopecia.

This study suggests that macrophages, particularly CD206⁺ macrophages, play a crucial role in squaric acid dibutylester-induced hair growth in alopecia areata treatment.

This study found that 3D-cultured dermal papilla cells more accurately mimic in vivo conditions compared to 2D cultures, enhancing our understanding of molecular mechanisms in androgen-induced alopecia.

In this study, researchers found that a scallop adhesive protein (Sbp9 Δ) forms strong adhesive coatings via disulfide-sticker strategies, which also promote hair regeneration in mouse models by activating Wnt signaling and enhancing angiogenesis, proving more effective than minoxidil for androgenetic alopecia.

In this study, quercetin nanocrystals stabilized with glycyrrhizic acid were developed as a new treatment strategy for androgenetic alopecia, which significantly reduced DHT levels and improved hair regrowth in a mouse model, indicating synergistic potential for clinical application.

This study found that Plerixafor, a CXCR4 antagonist, promotes melanogenesis in melanocytes by increasing MITF and tyrosinase expression and enhancing melanocyte migration, and it effectively restores pigmentation in a mouse depigmentation model without toxicity, highlighting its potential for treating pigmentary disorders.

This study found that subcutaneous injection of a CXCL12 neutralizing antibody significantly promoted hair growth in androgenic alopecia and inhibited hair loss in alopecia areata in mouse models, suggesting its potential as a promising treatment for hair loss.

This study investigates the potential of umbilical cord mesenchymal stem cells exosome (UCMSC-Exos) to promote hair growth, focusing on its mechanisms of action, though specific results are not reported.

This study found that HMGB1 enhanced hair growth by stimulating PGE2 production in human dermal papilla cells, suggesting a potential therapeutic target for alopecia treatment.

In this study, researchers found that disrupting EGFR signaling in mice led to increased inflammation and hair follicle damage but that inhibiting the JAK-STAT1 pathway could restore hair growth and skin function.

Hedgehog signaling is crucial for hair development, cadherins affect cell adhesion, neutrophils play a role in skin lesions, and BP230 autoantibodies impact skin stability.

In this study, researchers used Raman spectroscopy to identify melanin-specific features in mouse hair as potential biomarkers for gamma-radiation exposure, achieving a sensitivity of 88% and specificity of 83%, with classification accuracy declining over time beyond 7 days post-irradiation.

This study found that PSAT1 is a key regulator of cellular survival and regenerative capacity in cashmere goat hair follicle stem cells, highlighting its role in the SHF cycle and its potential as a target to boost cashmere fiber production.

This review explores the crucial role of regulatory T cells in skin wound healing, emphasizing their involvement in balancing immune responses and promoting regeneration. It also discusses Tregs' operations in fibrosis, keloidosis, and scarring, suggesting a potential avenue for novel treatments.

This study found that in women undergoing chemotherapy after breast surgery, topical minoxidil significantly shortened the duration of hair loss compared to a placebo without significant side effects.

This study found that interleukin-10 deficiency in B6 mice led to inflammatory milk production due to maternal stress, causing alopecia and hepatocyte steatosis in pups.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study shows that macrophage-induced TNF signaling can activate hair follicle stem cells and promote new hair follicle formation after wounding by regulating AKT/β-catenin pathways.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

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 source reports that scalp cooling is currently the only safe and FDA-cleared method to potentially reduce chemotherapy-induced hair loss, with about a 50% chance of maintaining sufficient hair to avoid needing a wig.

This study demonstrated that high doses of L-cystine and vitamin B6 effectively prevent doxorubicin-induced hair loss in mice.

This article reviews drug-induced hair and nail disorders and discusses their clinical recognition, underlying mechanisms, and potential treatment strategies, without presenting new research findings.

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 demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.
