In this study using guinea pigs, the low-dose 800 nm semiconductor laser was found to effectively treat skin blackheads and coarse pores by promoting hair follicle cell apoptosis, while maintaining PCNA expression levels in sebaceous glands.

This study found that facial sun damage scores from UV photography correlate with skin cancer and melanoma risk factors, suggesting this technology may help identify individuals at higher risk.

This study indicates that Samhwang-Sasimtang ethanol extract may promote hair growth in a mouse model, showing stronger effects than a control but less than 3% minoxidil.

This article reviews the genetic and androgenic factors influencing the development of androgenetic alopecia and reports no new findings; the authors highlight a need for further research into the underlying mechanisms.

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 S. scabiei infestation in rabbits leads to epidermal thickening possibly due to apoptosis-related proliferation and keratinization of the skin.

Male androgenetic alopecia involves hair follicle miniaturization due to DHT, with potential treatments using inhibitors and blockers.

This study found that DHT induces apoptosis in human keratinocyte cells via ERK activation, independently of androgen receptors and the Wnt/β-catenin pathway.

This review synthesizes findings from 15 animal studies on alopecia, identifying key biomarkers like TNF-α and IL-6 that suggest inflammation and follicular damage, offering insights into potential targeted therapies to balance degenerative and regenerative pathways for more effective treatment strategies.

In a mouse model, this study found that exposure to PM2.5 leads to significant postpartum hair loss, apparent via morphological changes and elevated markers of inflammation, apoptosis, and fibrosis, potentially exacerbated by changes in hormone receptors and stem cell populations.

In this laboratory study, researchers reported that Camellia sinensis seed flavonoids significantly reduced oxidative stress and inflammation in UV-irradiated skin cells by modulating key signaling pathways, highlighting its potential as a skincare ingredient for anti-inflammatory and anti-photoaging benefits.

In this study, researchers found that sesamin, a component of sesamum, modulated the AR-MAPK-Wnt signaling pathway in DHT-stimulated HaCaT keratinocytes, demonstrating potential multi-target activity against molecular events in androgenetic alopecia.

This study found that administering lycopene to rats provided significant protection against the testicular damage caused by finasteride, as indicated by improved sperm parameters, and reduced oxidative stress and apoptosis markers.

This research observed that removing RNase L in mice enhances regenerative capacity through increased IL-36 and wound-induced hair neogenesis, highlighting RNase L as a gene that represses regeneration by moderating immune responses during viral infections.

This study found that platelet-rich plasma might support brain health by enhancing glial cell function and modulating immune responses in inflammation, indicating potential as a treatment for brain disorders.

This study found that RNase L acts as a regeneration repressor gene in mammals, as seen in Rnasel-/- mice which showed increased regenerative capacity and elevated Wound Induced Hair Neogenesis through enhanced IL-36α signaling, suggesting a tradeoff between regeneration and immune regulation.

This study observed that treating basal and squamous cell carcinoma cells with platelet-rich fibrin significantly reduced cell viability and increased apoptosis-associated gene expression, suggesting potential use as adjunctive therapy for localized nonmelanoma skin cancers.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

In this study, baicalin, a component of Baikal skullcap, was found to inhibit necroptosis in a cellular model of toxic epidermal necrolysis, suggesting it may be effective against severe drug-induced skin eruptions.

This study investigated the effects of a YH complex, derived from Cinnamomum cassia and Astragalus membranaceus, on androgenetic alopecia in mice, finding that it promoted hair regrowth and improved hair follicle health by modulating hair cycle regulation and reducing apoptosis signaling pathways.

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.

In this study, Typhonium flagelliforme leaf-ethanolic extract combined with natural interferon was observed to stabilize body weight, inhibit tumor growth, and reduce mitosis, angiogenesis, and certain protein expressions in carcinogen-induced tumors in female mice, suggesting potential antitumor effects.

This study investigated the effects of HDDPiW-jSB solution on chemotherapy-induced alopecia in a rat model and found that the solution improved hair follicle health markers and reduced cell apoptosis, especially when applied twice weekly, while appearing safe for skin application.

This study found that PX-12 inhibited the NLRP3 inflammasome and reduced psoriasis-like symptoms in a mouse model, suggesting its potential as a treatment for psoriasis.

RNase L suppresses regeneration in mammals.

This study found that topical olive oil may protect mice skin from damage caused by electromagnetic radiation, particularly when applied before exposure, by mitigating oxidative, inflammatory, and heat shock stress factors.

In this study, IL-1α and IL-7 were found to work together to activate epidermal γδ T-cells, which in turn promote hair follicle stem cell proliferation during mouse wound healing.

This study found that mackerel fermented fish oil protected human keratinocyte cells from UVB-induced oxidative stress by scavenging free radicals and reducing cellular damage.

In this study, aspartame consumption during gestation in rats was associated with significant histological changes and increased apoptosis in the skin of their neonatal pups.
