In this study, the researchers found that the water-soluble fraction of Rhus semialata gall extract and its component Penta-O-Galloyl-β-D-Glucose promoted hair growth in human dermal papilla cells, and clinical trials supported these findings, showing improved hair density and appearance compared to placebo.

This study suggests that topically applied thyroid hormones T3 and T4 promote hair growth on human scalp tissues ex vivo, highlighting potential therapeutic use for hair loss conditions like androgenetic alopecia.

This study found that fibroblast growth factor 5 may enhance Cashmere goat hair growth by altering the expression of specific genes related to keratin and keratin-associated proteins.

This study suggests that fibroblast growth factors FGF-4, FGF-8, and FGF-9 may play redundant roles as signals in epithelial-mesenchymal interactions during multiple stages of tooth development in mice.

This review examines treatments for chemotherapy-induced alopecia, reporting that combining mechanical and chemical interventions may offer some benefits, though the evidence is not yet definitive.

This study found that the FGF-2 mimetic SUN11602 and VEGF mimetic ONO-1301 had unique effects on skin fibroblasts and keratinocytes, indicating potential for improving wound healing.

This review explores the molecular controls of hair follicle cycling and highlights the challenge of developing effective treatments for common hair disorders without providing new clinical results.

This study found that orally administered Annurca apple extract improved hair length, thickness, weight, and density in mice, while also increasing the expression of hair growth-related genes and proteins, suggesting potential as a natural treatment for hair loss.

This study found that Ashwagandha-derived nanovesicles increased cell proliferation, angiogenesis, and growth factor expression in vitro, suggesting they may have potential as a plant-based alternative or complement to current therapies for hair and skin conditions.

In this review, the authors report that topical minoxidil effectively stimulates hair growth in androgenic alopecia and to a lesser extent in nasal alopecia, particularly in early stages, with minimal and typically short-lived adverse skin reactions, but no systemic side effects.

This study found that while SP did not enhance linear hair growth in cultured hair follicles, it prolonged the anagen phase and altered the expression of growth factors and apoptosis-related molecules, suggesting a stimulatory effect on hair growth.

This study found that recombinant human type XVII collagen (rhCOL17A1) promotes hair growth by activating the Wnt/β-catenin and SHH/GLI signaling pathways and increasing type XVII collagen expression, with significant effects observed in both cell and mouse models.

In this study, compound glycyrrhizin promoted hair regrowth in a testosterone-induced alopecia mouse model and increased human hair dermal papilla cell proliferation, likely through activating the Wnt/β-catenin pathway.

In this mouse study, nitrate supplementation at 10mM was observed to significantly promote hair growth by increasing hair follicle number and dermis thickness, and it may work by activating the Wnt/β-catenin pathway and inhibiting TGF-β1 signaling.

Topical thyroid hormones may boost hair growth.

This study found that in mice, oral administration of Lactilactobacillus curvatus LB-P9 accelerated hair regrowth and increased hair thickness, hair follicle numbers, and dermal thickness, likely by boosting hair growth factor production and dermal papilla proliferation.

This review discusses the applications and research on fibroblast growth factors, including their use in wound healing, diabetes, and cancer, but it reports no new clinical results.

The study reports that Fgf18 and Tgf-β2 signaling pathways in hair follicle stem cells have opposing effects on the timing of hair cycle transitions, influencing the shift from telogen to anagen phases.

This study suggests that androgens enhance growth factor production in dermal fibroblasts, which in turn may alter keratinocyte differentiation and contribute to acne lesion formation.

This study demonstrated that safflower seeds can be engineered to express oleosin-FGF10, which showed a dose-dependent effect on cellular proliferation, potentially facilitating scalable protein production.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

In this study, researchers investigated a regulatory network in cashmere goat embryos and found that fibroblast growth factor 10, alongside non-coding RNAs, significantly influences hair follicle cell proliferation, offering insights into the biology of hair follicles in cashmere goats.

This study found that cucurbitacin cream reduced FGF18 levels and accelerated hair follicle transition to the anagen phase in mice, suggesting its potential as a treatment for hair regeneration.

This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.

This study found that in mice, inactivating beta-catenin in the dermal papilla reduces hair follicle progenitor proliferation and disrupts the hair cycle.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This study found that over-expressing Spry4 and Fgf10 modulates feather stem cells to alter feather morphologies in distinct ways, affecting barb branch formation and tissue structure.

This study found a significant association between reduced FGF13 levels and X-linked congenital generalized hypertrichosis, suggesting FGF13's potential role in hair follicle growth and the hair cycle.
