This review discusses nearly 70 patent applications for the treatment of androgenetic alopecia and other hair conditions, highlighting the mechanisms of action explored but reports no clinical results.

This article reviews the role of KLF4, a transcription factor, in various cellular processes and its dual function as a tumor suppressor or oncogene depending on the context, but presents no new experimental results.

This study investigated single-cell changes in photoaged skin, revealing distinct cell clusters and increased activity in PD-L1 and PD-1 pathways in sun-exposed areas, enhancing understanding of UVA-induced skin damage and potential prevention targets for photoaging and UV-induced skin cancers.

This study found that red ginseng extract may stimulate hair growth in a mouse model by enhancing dermal papilla cell proliferation and activating skin antioxidant defenses.

This study found that treating cashmere goat kids with melatonin significantly increased secondary hair follicle density, improving cashmere quality and yield, likely through mechanisms involving the MAPK signaling pathway.

This study suggests that the anti-inflammation and anti-oxidation properties of Taohong Siwu decoction may be linked to its effects on androgenic alopecia through specific biological processes and pathways.

This review highlights the critical role of microRNAs in regulating hair follicle biology, significantly impacting wool and cashmere development by modulating gene expression and signaling pathways in sheep and goats.

This study found that a natural illite-based carrier could deliver minoxidil topically with preserved efficacy, minimizing solvent toxicity, and showed hair-growth-promoting activity via anti-inflammatory and pro-proliferative mechanisms in mice.

This study found that overexpressing FGF22 in dermal papilla cells enhanced hair follicle stem cell proliferation and viability, while its knockout reduced these attributes, indicating its role in hair follicle regeneration.

This study observed that in a mouse model of androgenetic alopecia, treatments with LTF, 5% minoxidil, and LTF-DPC-EXO significantly promoted hair regeneration compared to the model group, potentially through modulation of the PI3K/AKT signaling pathway.

Early-stage skin substitutes improve wound healing and skin structure.

In this study, researchers found that crude extracts from Avicennia marina and its component avicequinone C inhibit mechanisms contributing to androgenic alopecia in vitro, including 5α-reductase activity and DHT-AR interactions, potentially promoting hair growth and delaying the catagen phase in human dermal papilla cells.

This study suggests that EDA-A2 induces apoptosis in hair follicles by increasing DKK-1 expression, implicating EDA2R signaling as a potential therapeutic target for androgenetic alopecia.

This study found that the highest rebound value in concrete with high volume slag occurs with 40% slag content, 10–20 mm basalt aggregates, and greater carbonation depth.

This study indicates that individuals exposed to PPD mount varying immune responses, with either tolerance, subclinical inflammation, or allergy, suggesting no true non-responders to PPD.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

This review discusses the critical role of BMP signaling in the development and regulation of skin and hair follicles and notes that further research could aid therapeutic advances; it presents no new clinical results.

This study found that maternal sub-maintenance nutrition reduced the density and branching ratio of secondary wool follicles in Merino sheep fetuses and identified genes potentially involved in these processes.

This study assessed 11 plants from French Polynesia for their potential development as sustainable natural cosmetics, particularly anti-aging and hair care products, based on their traditional uses and preliminary screening results.

In this study, researchers found that miR-143-3p may play a novel role in cashmere growth by directly repressing the expression of Itga6 in secondary hair follicles of goats.

This study in mice found that using modified illite as a carrier for topical minoxidil enabled effective delivery without the solvent toxicity typically associated with minoxidil, while the illite also promoted hair growth through anti-inflammatory and pro-proliferative mechanisms.

This study reported that a bioderived melanoidin/tannic acid nanocomplex forms a durable, antioxidant-active coating on hair fibers, providing enhanced UV protection and improving tensile resilience by suppressing oxidative stress and activating endogenous antioxidant pathways.

This study reviewed preclinical evidence suggesting that topical glutamic acid can enhance hair regrowth and skin healing in burn-induced alopecia, highlighting its potential as a simple, low-cost treatment option that warrants further clinical trials.

In this study, 2′‐Fucosyllactose (2′‐FL) administration significantly reduced hair loss and increased hair length and thickness in a testosterone-induced androgenic alopecia mouse model, suggesting potential as a therapeutic agent for AGA.

This review highlights potential therapeutic mechanisms of natural products for androgenetic alopecia, suggesting they may modulate signaling pathways and have anti-inflammatory and antioxidant effects.

This study reported that in mouse models, deletion of EGFR resulted in stem cell hyper-proliferation followed by apoptosis, leading to scarring alopecia, and implicated EGFR's role in maintaining hair follicle quiescence and immune privilege during inflammation.

Krox20 is crucial for hair growth and maintaining skin stem cells.

LED light helps human hair root cells grow and prevents them from dying by activating specific growth pathways.

This review discusses the role of various hormones in diffuse hair loss and emphasizes the need for further research to clarify their complex interactions and potential therapeutic implications, but reports no new clinical results.

This study found that Danthron induced apoptosis in a human malignant melanoma cell line through mitochondrial, endoplasmic reticulum, and death receptor pathways.
