In this study, researchers developed a method to measure steroid hormones in hair and found that body hair typically contains higher levels of cortisone and testosterone compared to scalp hair, but hair pigmentation did not affect hormone concentrations significantly.

This study found that filamin A plays a crucial role in fibroblasts' ability to sense and respond to mechanical stimuli, significantly affecting wound closure and fibroblast-mediated processes in mice.

In this study, researchers found that exposure to PM10 significantly increased inflammation and impaired collagen synthesis in human dermal fibroblasts, suggesting PM10 contributes to skin aging through these mechanisms.

In this study, topical application of ginsenosides Rb₁ and Rd in mice increased cell proliferation in hair follicles, suggesting they may help prevent hair loss by promoting growth through p63 induction.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This study found that subthermal CRET treatment increased keratinocyte proliferation and modulated cytokine production, affecting the inflammatory response in human keratinocytes through EGFR and ERK1/2/NF-κB pathways.

This study found that combining IGF-1 and EGF in specific concentrations significantly stimulated hair follicle growth in vitro for primary follicles from Liaoning cashmere goats.

Tanshinone Capsule may help regrow hair by boosting specific cell signals.

This study found that ginseng-derived nanoparticles promoted skin cell proliferation and facilitated wound healing in a mouse model.

This study suggests that exosomal miRNAs from human amniotic fluid stem cells may inhibit myofibroblast differentiation and reduce fibrotic scarring in wound healing.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

This study demonstrated that β-catenin signaling in CD133+ dermal papilla cells enhances postnatal hair growth by accelerating the proliferation and differentiation of keratinocytes in the murine hair cycle.

This study suggests that systemic exposure to black eyeliner pigment may occur, potentially leading to permanent eyelash loss following the procedure.

In this study, fractional laser treatment was observed to reverse age-related gene expression changes in skin and enhance dermal remodeling, further improved by multiple treatments.

This study found that transplantation of autologous stromal vascular fraction cells increased skin thickness and improved regeneration when combined with mechanical stretching, without severe adverse events.

This study found that Pomiferin may effectively stimulate extracellular matrix protein expression in skin and scalp models, with results comparable to retinol, suggesting potential as a topical treatment ingredient.

This study found that single-dose x-ray irradiation in rat calvaria skin led to morphological changes in collagen fibers, disorganization, and a temporary absence of sebaceous glands and hair follicles.

In this study, collagen scaffolds functionalized with heparin and growth factors significantly enhanced long-term skin regeneration and growth in a sheep model of fetal skin defect, suggesting potential for prenatal spina bifida treatment.

This study found that overexpression of R-spondin 3 in a mice model impaired hair morphogenesis and regeneration by reducing hair matrix progenitor cell proliferation, thus disrupting the Wnt pathway's regulation of stem cells.

This study found that EGCG improved the integrity of skin grafts during cryopreservation, suggesting its potential usefulness for skin preservation, though the exact mechanism remains unclear.

This study found that the purified compound VB1 from Vitex negundo seeds may reduce UVA-induced skin aging by targeting MAPK1 and demonstrated its potential in mice.

This study found that a 12-week supplementation with MePL, a solution of miliacin encapsulated within polar lipids, significantly reduced hair density in the telogen phase and improved scalp dryness and hair brightness in women with telogen effluvium.

This study found that adding dithiodiglycolic acid to the hair straightening process decreased chemical damage and preserved the structural integrity of the hair matrix compared to using thioglycolic acid alone.

In this study, mesenchymal stem cell therapy improved erectile function in a rat model of diabetes-associated erectile dysfunction, and identified 15 hub genes potentially involved in the condition's development.

This study found that treating permed hair with diethylene glycol monoethylether significantly reduced the formation of split ends, making it similar to untreated normal hair in terms of split ends generation.

This study's literature synthesis suggests that silymarin, derived from milk thistle, may offer protective benefits for the skin, including defense against UV damage and support for wound healing, though further clinical studies are needed.

This study reports that Edelweiss extract significantly prolonged the anagen phase and increased hair density, suggesting potential as an anti-hair loss treatment.

This study found that corticotropin-releasing factor influences cytokine expression related to hair growth in human dermal papilla cells and suggests CRF receptor antagonists could be potential treatments for stress-induced hair loss.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.
