In this double-blind randomized controlled trial, both rosemary extract lotion and 2% ketoconazole lotion were effective for treating scalp seborrheic dermatitis, but rosemary lotion reduced itching more significantly, while ketoconazole was more effective in reducing dandruff.

In a systematic review and meta-analysis, the researchers found that intralesional triamcinolone acetonide was more effective than cryotherapy for achieving significant hair regrowth in patients with patchy alopecia areata, although both treatments had distinct safety profiles.

This review discusses different types of alopecia associated with psoriasis and highlights that hair loss in psoriasis is typically non-scarring and reversible, while also noting the increased risk of alopecia areata in these patients.

This study found that ChatGPT 4.0 and Gemini 1.5 Flash provided more accurate and user-friendly responses to androgenetic alopecia questions than Deepseek R1, suggesting they could be effective tools for patient education with physician guidance.

Perinevoid alopecia can be effectively treated with non-invasive corticosteroids.

This study found that topical immunotherapy was effective in 56.83% of pediatric patients with alopecia areata, but those with co-occurring atopic dermatitis were more likely to show an inadequate response to treatment.

This study found that pulse corticosteroids effectively induce hair regrowth in alopecia areata, with betamethasone showing higher efficacy but more side effects, and treatment success varying depending on age, onset time, and disease type.

Some lung cancer patients treated with EGFR inhibitors may develop a hair loss condition similar to folliculitis decalvans.

This study observed that a tacrolimus solution (0.1%) applied to the scalp was effective and well-tolerated for treating inflammatory scalp conditions, with 72.7% of patients showing an excellent response after 2 months of treatment, which persisted after 6 months.

In this study, researchers evaluated factors influencing alopecia areata recurrence and identified male gender and a family history of the condition as independent predictors for disease recurrence among the 100 patients analyzed.

In this laboratory study, Camellia japonica fruit shell extract showed potential to mitigate hair loss by promoting hair cell growth and reducing harmful effects of DHT and oxidative stress.

This study found that non-balding dermal papilla cells emphasized extracellular matrix organization and reduced inflammation when cultured in 3D or with adipose-derived stem cells, unlike balding cells which maintained inflammatory pathways.

This study found that the mitotic arrest deficient protein MAD2B negatively affects TCF4-induced growth and proliferation of dermal papilla cells, which are vital for hair follicle development.

In this study, exosome-mimetic nanovesicles derived from neural progenitor cells promoted hair follicle regeneration in mice by activating the Wnt/β-catenin signaling pathway.

This study analyzed the features of alopecia areata incognita and diffuse alopecia areata, finding distinct patterns in hair loss regions and trichoscopic signs, and noted a benign course responsive to topical steroid therapy.

In this review, the authors evaluated the potential of using the second to fourth digit ratio (2D:4D) as a predictor for androgenetic alopecia, suggesting future research directions but not reporting definitive results.

This study found that untreated hirsute patients have lower expression of type 2 17β-HSD mRNA in scalp hairs, indicating potential disturbances in androgen metabolism, compared to treated hirsute patients.

This study introduced a reproducible human model using 3D-SeboSkin technology to study hidradenitis suppurativa, allowing better maintenance of skin integrity and replication of biomarker expression patterns compared to traditional skin cultures, suggesting its value for further research.

This study demonstrated that enhancing human skin constructs with hair follicles through engineered cell organization and vascularization improved hair growth in immunodeficient mice, suggesting potential advances for treating alopecia and chronic wounds.

This study found that Polygonum multiflorum extract may promote hair growth by increasing anagen duration and activating dermal papilla cells in human hair follicles, as observed in cultured cell models.

This study found that androgens downregulate BMP2 in dermal papilla cells, inhibiting hair follicle stem cell differentiation, while BMP2 addition may restore hair lineage differentiation through the Wnt/β-catenin pathway.

This study suggests that human dermal fibroblasts can be converted into dermal papilla cell-like cells using microencapsulation, which may facilitate hair follicle regeneration in mice without chemical or genetic reprogramming.

This study found that alginate spheres maintain dermal papilla cells in a dormant state with increased trichogenecity, suggesting potential benefits for cell therapy in androgenic alopecia.

This study found that male liver cirrhosis patients have higher estradiol levels and lower dehydroepiandrosterone sulfate, leading to hormonal imbalances favoring estradiol, but without changing sex hormone-binding globulin's binding properties.

The document concludes that scalp conditions have various causes and can present in many different ways.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This study found that the human placenta extracellular matrix hydrogel restored the hair-inductive capacity of high-passaged dermal papilla cells, enabling them to regenerate new hair follicles when co-grafted with mouse epidermal cells.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.
