This study found that EGCG from green tea may stimulate human hair growth by promoting the proliferation and anti-apoptotic activity in dermal papilla cells.

This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This study found that SZ95 sebocytes and HaCaT keratinocytes exhibit distinct enzyme expressions and activities, implicating their different roles in androgen metabolism and homeostasis in vitro.

This study found that alkylation of kerateine cysteine residues created a cell-compatible method for controlling hydrogel erosion rates and therapeutic agent release in keratin-based systems.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This study found that blue light at a wavelength of 453 nm promoted hair growth ex vivo, potentially through interacting with OPN3 receptors in human hair follicles.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This study found that cyclosporin A treatment enhances hair growth in mice by inhibiting calcineurin-NFAT1 activity, which alters keratinocyte differentiation and apoptosis-related gene expression in hair follicles.

This study identified LY191704 as a specific noncompetitive inhibitor of human 5 alpha-reductase type 1, which may be useful in treating endocrine disorders related to DHT overproduction.

This review discusses emerging treatments and mechanisms for alopecia, highlighting potential therapies like janus kinase inhibitors and advances in stem-cell technology, but reports no new experimental results.

This study found that Insig deficiency in the skin of mice causes cholesterol precursors to accumulate, leading to defective hair development and skin abnormalities, which were alleviated by simvastatin treatment.

This study found that a eupafolin nanoparticle delivery system improved water solubility and skin penetration, enhancing its antioxidant and anti-inflammatory effects against particulate matter-induced stress in skin cells.

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 letter reports a series of cases where the use of ruxolitinib at a lower dose than previously studied led to hair regrowth in patients with severe alopecia areata.

This study found that combining minoxidil and retinol additively promoted hair growth in vitro, enhancing Erk- and Akt-dependent pathways and preventing apoptosis in dermal papilla cells and keratinocytes.

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 found that manipulating prolactin levels in New Zealand Wiltshire sheep induces wool follicle growth cycles, revealing gene expression changes that suggest roles for specific genes in follicle function.

In this study, herbal extracts commonly used in traditional medicine were observed to significantly increase the proliferation of human dermal papilla cells, suggesting potential as alternative therapies for enhancing hair growth.

This study indicates that activating K+ channels in dermal papilla cells alone may not promote hair growth, despite some openers being effective on certain channels.

This study found that synthetic melanin particles applied topically in mouse injury models improved wound healing, showing potential as a therapy for accelerated healing, including in human skin explants.

This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.

This study found that 6-gingerol, a component of ginger, suppresses hair growth rather than promoting it, both in vitro and in vivo, suggesting potential use in hair removal treatments.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

This study found that the humanin analogue HNG significantly promoted hair growth in vitro and in vivo by prolonging the anagen phase and inhibiting hair follicle cell apoptosis in mice.

In this study, around 1% of proteins in skin fibroblasts significantly changed in response to reductive stress, affecting collagens and MAPK signaling pathways.

This study found that DNMT1 promotes adipogenesis in hair follicle stem cells by regulating the miR-214-3p/MAPK1/p-ERK1/2 pathway, suggesting potential applications in stem cell therapy.

This study found that Bazhengsan significantly reduced inflammation and hyperplasia in male rats with nonbacterial prostatitis, indicating potential as a treatment for chronic prostatitis.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study found that low-level laser therapy effectively reduced relapse rates, while functional appliances did not; combining them offered no additional benefits.

In this study, researchers observed that dandruff involves altered keratinocyte activity and a low-grade inflammatory response characterized by increased interleukin-17-producing T-cells and CCL17 levels, but without significant changes in immune cell populations or skin barrier lipids.
