This review suggests that linoleic acid, an essential fatty acid, may have various beneficial effects on skin health and hair growth through diverse biological activities observed in animal or skin cell models.

This study found that early-onset male androgenetic alopecia is associated with abnormal lipid metabolism and lower levels of certain serum markers, which may serve as risk factors or protective factors for the condition.

This review explores adult female acne, focusing on its multifactorial causes, treatment options, and impact on quality of life, but reports no new clinical results.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

Adipose stem cell exosomes may effectively treat atopic dermatitis by reducing inflammation and improving skin health.

Mutations in Far2 mice cause hair loss due to sebaceous gland issues.

Apoptosis may play a role in feather and hair development, SF-36 is better for mental health in skin patients, a psoriasis gene is found in Caucasians, eosinophils might not be crucial for some skin allergies, and changes in atopic dermatitis could increase skin sensitivity.

The document concludes that individualized treatments for hair issues are effective, certain hair changes can indicate neurocutaneous diseases, specific lotions improve skin health, laser hair removal works but needs more study on long-term effects, men's cosmetics are diverse, peeling is effective but can have side effects, and facial pigmentation is often due to overactive skin cells.

This study found that inactivating CerS4 in mouse epidermis disrupts lipid homeostasis and is crucial for maintaining, but not forming, the skin barrier.

In this study, inducible whole-body Acly-knockout mice revealed that ACLY is essential for skin homeostasis, as its deficiency led to increased sebum production and skin abnormalities, indicating a vital role for cytosolic acetyl-CoA synthesis in preserving skin barrier integrity and systemic lipid regulation.

Addressing biological changes in lipids, metabolism, and microbiota may help treat hair loss in young Chinese females with oily scalps.

This study's simulation found that Ascorbyl Tetraisopalmitate penetrates more efficiently through the skin's stratum corneum than via the infundibulum, following different pathways and dynamics in each membrane.

This study suggests that decreased levels of dihydroceramide in hair may serve as a biomarker for the progression of alopecia.

This study demonstrated that dominant mutations in mouse gasdermin A3 disrupt mitochondrial oxidative stress regulation, suggesting a gain-of-function effect on epidermal differentiation.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.

This study found that maternal consumption of a western diet in mice led to toxic milk production, causing inflammation and alopecia in nursing neonates due to Toll-like-receptor activation.

Ceramide Synthase 4 is crucial for healthy skin barrier function.

This study reports that a plant extract from Orobanche rapum can stimulate skin rejuvenation and protect cutaneous microbiota, potentially creating healthier skin.

In this study, researchers found that Ectoin, derived from halophilic bacteria, can mitigate stress-related skin damage by reducing cortisone's inhibitory effects on essential skin proteins and decreasing UVB-induced glucocorticoid activity, highlighting its potential as a preventative agent for stress-induced skin issues.

This study found that dihydrotestosterone (DHT) may shorten the hair growth cycle through mechanisms like cell-cycle arrest and β-catenin downregulation in rat hair follicle cells.

This research indicates that KCED-1 and KCED-2 effectively induce adiponectin production in human subcutaneous fat, which may promote hair growth on the scalp.

This study found that loss of the ACER1 gene in mice led to increased ceramide levels and progressive hair loss, highlighting ACER1's role in maintaining hair follicle stem cell homeostasis.

In this study, orally administered Centella asiatica extract, standardized for asiaticoside content, significantly improved skin barrier function, elasticity, and reduced signs of UVB-induced photoaging in hairless mice, highlighting its potential as a nutricosmetic for skin health.

This study reported that bio-pulsed avian-derived mesenchymal stem cell extracellular vesicles significantly improved cell proliferation, wound healing, and gene expression in human skin fibroblasts and hair follicle cells.

This review summarizes recent genetic research on hidradenitis suppurativa, highlighting potential therapeutic targets and genetic mutations, but reports no new clinical findings.

This study demonstrated a novel use of tape stripping on a human skin model to simulate the inflammation and barrier damage caused by dry razor shaving, highlighting potential shaving and skin-care formulations that may mitigate such damage.

In this review, the authors emphasize the importance of understanding drug chemical structures to help general physicians better manage and treat acne, although no specific results are reported.

Targeted therapies for lung cancer are effective but require careful management of side effects to benefit patients.

This study found that bioconjugating 16-methylheptadecanoic acid (16-MHA) to damaged hair can mimic the protective properties of 18-methyleicosanoic acid (18-MEA), restoring the hair's structural integrity and moisture homeostasis, even after washing.

In vitro skin models are improving but still need more innovation to fully replicate human skin.
