This review discusses major advances in understanding inherited hair diseases through genetic research and reports no new clinical results; the authors emphasize the potential for new preventive and therapeutic tools.

This study found that l-carnitine stimulated hair growth in vitro by promoting proliferation and reducing apoptosis in human scalp hair follicles, suggesting potential as a treatment for hair loss.

This study found that phenyl-imidazole sulfonamide derivatives, particularly ISCK03, inhibited c-kit signaling and promoted depigmentation in various experimental settings, suggesting potential use as skin-whitening agents.

In this analysis, safety data from two clinical trials showed that baricitinib for severe alopecia areata had predictable side effects like infections and elevated CPK, with some serious adverse events noted at low incidence rates; no deaths were reported.

In this study, researchers found that deleting Caspase-9 in hair follicle stem cells delayed apoptosis, leading to accelerated wound repair and new hair follicle regeneration by maintaining apoptotic cells as signaling centers.

This study found that morroniside enhanced hair follicle growth and transition through the Wnt/β-catenin signaling pathway in a mouse model, suggesting its potential as a treatment for hair loss.

This study found that Gsdma3 mutation in mice allows hair follicles to bypass a typical telogen phase and directly enter the anagen phase, suggesting Gsdma3's role in hair cycle transitions by regulating Wnt signaling.

This study created a humanized mouse model of hereditary vitamin D-resistant rickets that lacks alopecia, indicating the mutant receptor's potential to explore the syndrome's characteristics beyond vitamin D binding.

This review discusses recent advancements in cutaneous drug delivery technologies and the potential of transfollicular pathways for improved treatment of skin conditions, but reports no clinical results.

This article reviews complications associated with modern hair transplant surgery and discusses their treatment and prevention but reports no new clinical results.

This study identified a novel gene, hacl-1, that is specifically expressed in the hair follicles of ICR mouse skin and is associated with their active state.

This study demonstrated that a bio-3D printed artificial skin scaffold, seeded with adipose-derived mesenchymal stem cells, showed promising wound healing properties by enhancing cell recruitment, migration, and gene expression related to tissue regeneration.

This study reported that a new laser scanner using 655 nm red and 808 nm infrared lasers significantly improved hair density in patients with androgenic alopecia compared to both a laser hat and no treatment, without observable adverse effects.

This study found that pretreating mouse skin with microneedles significantly enhanced the hair growth inhibitory effect of eflornithine cream, likely by improving its skin permeation.

This study found that dihydrotestosterone induced hair loss and changes in hair morphology in male C57BL/6 mice, effects that could be partially reversed by the AR antagonist bicalutamide.

This review explores recent insights into how intrinsic gene oscillations and molecular interactions in hair follicle stem cells contribute to their regenerative potential, with potential implications for regenerative medicine, but reports no new clinical results.

In this study, DHT was observed to have varying effects on hair follicle growth and related protein expression depending on concentration, with the Wnt/β-catenin pathway potentially playing a significant role.

In this mouse study, NF-κB was shown to play a role in hair follicle cycling and morphogenesis, with specific activity patterns differing by hair type and involving noncanonical signaling for zigzag hair bending.

This study found that among Filipino women, a modified Ferriman-Gallwey score of 7 or above indicates hirsutism and is significantly associated with elevated calculated free testosterone.

This study suggests that icariin promotes hair follicle growth in mice by enhancing IGF-1 expression in dermal papilla cells.

This study found that ginsenoside F2 may suppress hair cell apoptosis and improve hair growth outcomes in a DHT-induced hair loss model more effectively than finasteride.

In this study, researchers found that impaired cholesterol biosynthesis in hair follicles may trigger an inflammatory immune response linked to primary cicatricial alopecia, providing new insights into the disorder's pathogenesis.

This review discusses the etiology, diagnosis, and management strategies for hirsutism, noting that serious underlying disorders are rare and emphasizing targeted treatment to manage testosterone's effects.

This study found that Erica multiflora extract promotes hair growth by enhancing dermal papilla cell activity and shifting hair follicles from the telogen to the anagen phase in both in vitro and in vivo models.

In this case report, researchers identified Arthroderma vanbreuseghemii as the cause of a familial fungal infection, which was successfully treated with itraconazole and topical terbinafine cream.

This study suggests that a mixture of 5‐ALA and iron ion significantly improved hair growth in mice, comparable to minoxidil, without promoting keratinocyte or fibroblast proliferation in vitro.

This study found that subcutaneous injections of guanethidine or 6-hydroxydopamine induced premature hair growth in mice, suggesting a role for sympathetic nerves in hair growth control.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

This study identified 14 genes affected by copy number variants that may contribute to alopecia areata, including four genes notably involved in autophagy and chromatin remodeling.

This review discusses the most popular non-surgical cosmetic procedures for men and highlights the importance of considering sex-specific factors for optimal treatment, but reports no new clinical results.
