This study demonstrated that engineered exosomes carrying EGF and FGF restored hair density and follicle integrity in an androgenetic alopecia mouse model by reactivating hair follicle growth factors, offering a novel therapeutic approach without immunogenic reactions or systemic toxicity.

This study found that human umbilical cord mesenchymal stem cells (hUCMSCs) promoted hair regeneration in androgenetic alopecia model mice by activating Wnt/β-catenin signaling, enhancing hair follicle stem cell proliferation, and reducing dermal papilla cell apoptosis.

This study concluded that S. hexaphylla extract may improve androgenetic alopecia by reducing 5α-reductase and androgen receptor levels, inhibiting apoptosis, and promoting keratinocyte proliferation in experimental models.

This study found that miR-148a plays a significant role in regulating skin homeostasis and hair follicle cycling, influencing stem cell activity and development in mice.

This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

This review evaluates the potential benefits and mechanisms of blue light therapy for skin conditions like atopic dermatitis and acne, but highlights the need for further research on safety and clinical protocols.

This study found that vanillic acid from wheat bran promoted dermal papilla cell proliferation, potentially stimulating hair growth by activating the PI3K/Akt and Wnt/β-catenin pathways.

This study found that transient inhibition of eIF4E in a transgenic mouse model protected against cyclophosphamide-induced hair loss by inducing cell cycle arrest and reducing cellular apoptosis.

This study found that human hematopoietic mesenchymal stem cells increased the viability and migration of human outer root sheath cells in an in vitro alopecia areata model, involving Wnt/β-catenin and JAK/STAT pathways.

CD34 is a marker for isolating stem-like cells in mouse hair follicles.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study found that PTEN regulates the number and genomic stability of hair follicle stem cells in the skin, with its deficiency leading to increased stem cell accumulation and senescence through interactions with BMAL1 and BMI-1.

In this study, pantothenic acid at 20 μg/ml was observed to promote dermal papilla cell proliferation and migration, likely through up-regulation of ID3 and inhibition of Notch signaling.

In this study, zinc supplementation at 2.00 g/camel/day improved hair growth in lactating camels but did not affect milk production, while for calves, doses of 0.50–0.75 g/camel/day enhanced growth and hair development.

This study suggests that in gilthead seabream, DHT is involved in the onset of the meiotic phase of spermatogenesis and influences serum levels of E2 through regulation of aromatase activity.

This study found that ocu-miR-205 promotes the apoptosis of dermal papilla cells and the transformation of hair follicles from growth to regression and resting phases in Rex rabbits.

This study identified a novel phase of stem cell quiescence, GAlert, in mice, regulated by mTORC1, that primes stem cells for injury response.

This study utilized a UHPLC-HRMS method to identify eight active pharmaceutical ingredients, such as ketoconazole and minoxidil, in 26 out of 100 analyzed cosmetic products.

In this study, PEGDE above 10,000 μg/mouse caused subcutaneous toxicity including ulceration in mice, but did not affect liver, spleen, or kidney tissues.

In this study, yeast fermentation of Platycladus orientalis leaves was shown to enhance hair growth-promoting properties by affecting cell cycle phases in human dermal papilla cells, increasing growth factor VEGF, reducing inflammatory factor TGF-β1, and altering the expression of Wnt/β-catenin pathway-related genes.

This study found that Undariopsis peterseniana extract may promote hair growth by activating specific cellular pathways, suggesting potential for treating alopecia.

This study suggests that while VDR is crucial for maintaining hair follicles in mice, their degeneration may be linked to impaired cell migration during hair growth phases rather than stem cell loss.

In this animal study, rosehip seed oil applied to the skin of mice promoted hair regrowth by accelerating hair follicles' transition from resting to growth phases and increased hair follicle density, bulb size, and skin thickness, suggesting potential as a treatment for hair loss.

This study found that red light exposure significantly enhanced the growth, phytochemical content, and therapeutic potential of Eclipta alba callus cultures compared to other multispectral light exposures.

This study reports that in a rat model of myocardial infarction, Zn-Cu ion sequential therapy improved cardiac function and cardiomyocyte metabolic activity by precisely regulating ion concentrations and maintaining elevated levels of the Per2 protein, important for cellular repair.

This study measured the amounts of thiamine and riboflavin in Bogura's Geographical Indication branded yogurt and whey, finding them rich in these vitamins, which are beneficial for health.

This study found that ocu-miR-205 affects signaling pathways, promoting the apoptosis of dermal papilla cells and influencing hair follicle density in Rex rabbits.

This study found that ocu-miR-205 promotes apoptosis in dermal papilla cells, alters hair follicle signaling pathways, and affects hair density in Rex rabbits.

This review discusses treatments for chemotherapy-induced alopecia, highlighting scalp cooling for hair loss prevention and 2% topical minoxidil for regrowth acceleration as effective options, but reports a need for more rigorous trials to validate promising new therapies.

This study evaluated a hair growth gel with Hibiscus rosa sinensis, Eclipta alba, and Solanum nigrum extracts, demonstrating consistent homogeneity, 5 α-reductase inhibitory activity, and no skin irritation.
