This study observed that in young women, the scalp microbiota is influenced by sebum level, barrier sensitivity, and lifestyle factors, with barrier sensitivity emerging as a key factor, offering insights for further research into scalp health and conditions.

In this study, researchers found that the lipid composition in hair significantly affects water diffusion and may explain differences in dyeing and cosmetic treatment responses between Asian and European hair, with CP2 fibers having more lipids than CP3 fibers.

This study synthesized and evaluated hydroxycinnamate derivatives for their ability to inhibit human SRD5A1, finding that three compounds showed significant inhibitory activity and low cytotoxicity. Compound 10a notably reduced SRD5A1 protein expression in cells, suggesting potential for nonsteroidal treatment of androgen-related conditions.

This study found that peroxide-rich plasma-activated water caused minimal morphological damage to hair, while nitrate-rich plasma-activated water induced significant damage, especially in porous hair types.

This study found that injecting mouse hair follicle-derived mesenchymal stem cells (moMSCORS) into C57BL/6 mice reduced the incidence and severity of type 1 diabetes by modulating immune responses, suggesting potential for therapeutic use due to their immunosuppressive effects.

In this randomized controlled trial involving breast cancer patients undergoing chemotherapy, this study investigated the efficacy of low-level light therapy for preventing hair loss, measuring outcomes like hair count and patient quality of life, but the abstract does not report specific results.

In this study involving genetically modified rats, researchers observed that specific mutations in the vitamin D receptor affect calcium levels and bone formation, emphasizing the receptor's role in maintaining healthy bone density and its importance in regulating hair cycle and skin health.

This animal study found that finasteride, a 5-alpha reductase type 2 inhibitor, decreased dihydrotestosterone levels and c-Fos protein activation in the rat brain, but these effects may diminish after discontinuing the drug.

In this study, gene therapy using a VDR-expressing adenoviral vector promoted hair growth in Vdr-KO rats, suggesting its potential for treating alopecia associated with type II rickets.

This study found that dihydrotestosterone treatment may be more beneficial for height in children with 5-α-reductase type 2 deficiency compared to testosterone enanthate, especially in the prepubertal period.

This study found that hair dyed with anionic basic hair dye lost more color after shampooing compared to cationic and nonionic dyes, with alkaline shampoo increasing this effect.

This study identified significant metabolic differences between volar and non-volar skin in mice, revealing distinct amino acid, sugar, and nucleotide metabolism patterns associated with skin type differentiation.

This study provides evidence that innate lymphoid cells-type 1 can induce alopecia areata in human hair follicles, challenging the view that it is solely a CD8+ T cell-driven autoimmune disease.

This study found that intracrine androgen signaling, mediated by steroid 5α-reductase, is essential for optimal decidualization and vascular development in the endometrium during pregnancy, indicating potential targets for improving age-related fertility issues.

This study found that caffeic acid amide derivative, compound 4, effectively inhibited steroid 5α-reductase type 1 in vitro, suggesting potential for development as a treatment for androgenic alopecia.

This study demonstrates that Sox2-positive dermal papilla cells specify particular hair follicle types by showing heterogeneity in gene expression and pathway activation in these cells.

This article discusses the FDA's decision not to approve 5α-reductase inhibitors for prostate cancer prevention, citing an increase in high-grade tumors but no mortality evidence, and reports no new results.

This study describes the expression patterns of type I inner root sheath keratin proteins K25–K28 in human hair follicles, highlighting their distinct distribution within different layers.

In this study using human cell cultures, type 1 5α-reductase was found to vary in both protein heterogeneity and expression levels across different types of skin cells.

This review discusses the mechanisms behind hair patterning during mouse embryonic development and reports no new experimental findings.

This article discusses the development and clinical progress of PROTAC technology, particularly focusing on the New Drug Application for vepdegestrant, an estrogen receptor-targeting PROTAC, marking significant advancements in targeted protein degradation therapies.

This study isolated and characterized two distinct types of caspase-like proteases from human epidermis, suggesting their involvement in keratinocyte differentiation and apoptosis processes.

This research concludes that adipose mesenchymal stem cells are uniquely evolved to manage skin inflammation in newborns and their released molecules are the safest and most effective for skin therapeutics.

In a murine model of androgenetic alopecia, this study found that the newly designed IGF-1 biomimetic peptide Ac-GFFY-IGF led to faster and superior hair regrowth compared to minoxidil, suggesting potential for improved human therapies.

This case study described a girl with vitamin D-dependent rickets type 2A who developed long-standing tertiary hyperparathyroidism, yet this did not hinder the healing of her rickets or normalization of hypophosphatemia; high doses of intravenous calcium were pivotal for recovery.

This study found that critically ill pulmonary patients with deficiency syndrome were at a higher risk of developing type 2 myocardial infarction than those with phlegm syndrome.

This study in Mexican patients with alopecia areata found that body hair involvement was linked to disease progression, while treatment adherence was associated with both remission and progression.

This study found that early initiation of phototherapy is an effective treatment strategy for certain subtypes of AA, particularly in older patients and those with a shorter disease duration.

In this study, researchers identified that the oncomodulin protein lineage, specifically the gene pvalb8, plays a crucial role in the development and function of auditory hair cells in zebrafish by promoting cell proliferation through the Wnt signaling pathway.

This study found no significant difference in the risk of poor glycemic control between men with type 2 diabetes using tamsulosin and those using finasteride.
