research Micro-segmental analysis of the entry pathway and distribution of zolpidem in hair from different scalp regions after a single dose
Zolpidem shows up in hair from the top back of the head after one dose and fades over time, suggesting it gets into hair through blood and sweat.
research Exogen hair characterization in human scalp
The conclusion is that exogen is a unique hair cycle phase and the new sampling method specifically targets this stage, which may help in future hair loss research.
research Epidemiological Assessment of Testosterone Levels in Women Population: A Factorial Analysis of Cell Proliferation
High testosterone levels in 20% of the women studied may indicate PCOS, while 80% had low levels with potential health impacts.
research Potential health risk and levels of heavy metals in water resources of lead–zinc mining communities of Abakaliki, southeast Nigeria
Water near Abakaliki mines has high toxic metal levels, posing health risks.
research Bioavailability of Albumin-Bound Testosterone†
Spironolactone treatment increases the amount of testosterone available in the body.
research Probing the Effects of Stress Mediators on the Human Hair Follicle
Stress-related substance P may lead to hair loss and negatively affect hair growth.
research Mesenchymal Stem Cells from Adipose Tissue in Clinical Applications for Dermatological Indications and Skin Aging
Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.
research Therapeutic anti-inflammatory potential of formyl-peptide receptor agonists
Formyl-peptide receptor agonists could be new anti-inflammatory drugs.
research Testosterone and doping control
The document concludes that better biomarkers are needed to detect long-term oral testosterone use in athletes.
research Extracellular Matrix Degradation Products and Low-Oxygen Conditions Enhance the Regenerative Potential of Perivascular Stem Cells
Low-oxygen conditions and ECM degradation products increase the healing abilities of perivascular stem cells.
research A Comprehensive Pathophysiology of Dandruff and Seborrheic Dermatitis – Towards a More Precise Definition of Scalp Health
The document concludes that dandruff and seborrheic dermatitis are linked to inflammation and skin changes, and treating them with specific shampoos can reduce these issues.
research Hair cycle-specific expression of versican in human hair follicles
Versican, a protein, is less present in thinning hair follicles and this decrease might contribute to common hair loss in men.
research Characterization of the serotoninergic system in the C57BL/6 mouse skin
Mouse skin can produce and process serotonin, with variations depending on hair cycle, body location, and mouse strain.
research Air Pollution, Autophagy, and Skin Aging: Impact of Particulate Matter (PM10) on Human Dermal Fibroblasts
Air pollution (PM10) increases skin inflammation and aging by reducing collagen and may trigger a repair response in skin cells.
research Identifying novel strategies for treating human hair loss disorders: Cyclosporine A suppresses the Wnt inhibitor, SFRP1, in the dermal papilla of human scalp hair follicles
Cyclosporine A may help treat hair loss by blocking a protein that inhibits hair growth.
research Susceptibility variants on chromosome 7p21.1 suggest HDAC9 as a new candidate gene for male-pattern baldness
A gene called HDAC9 might be a new factor in male-pattern baldness.
research Effect of topical application of raspberry ketone on dermal production of insulin-like growth factor-I in mice and on hair growth and skin elasticity in humans
Raspberry ketone may help grow hair and improve skin elasticity.
research Phytochemical analyses of Ziziphus jujuba Mill. var. spinosa seed by ultrahigh performance liquid chromatography-tandem mass spectrometry and gas chromatography-mass spectrometry
The study found that Ziziphus jujuba seeds contain beneficial compounds for treating insomnia and anxiety and that the methods used are effective for assessing their quality.
research Cell wall-associated ROOT HAIR SPECIFIC 10, a proline-rich receptor-like kinase, is a negative modulator of Arabidopsis root hair growth
ROOT HAIR SPECIFIC 10 (RHS10) reduces the length of root hairs in Arabidopsis plants.
research Melatonin promotes Cashmere goat (Capra hircus) secondary hair follicle growth: a view from integrated analysis of long non-coding and coding RNAs
Melatonin helps Cashmere goats grow more hair by affecting certain genes and cell pathways.
research Characterisation of cell cycle arrest and terminal differentiation in a maximally proliferative human epithelial tissue: Lessons from the human hair follicle matrix
CIP/KIP proteins help stop cell division and support hair growth.
research Inducing hair follicle neogenesis with secreted proteins enriched in embryonic skin
Three specific proteins can turn adult skin cells into hair-growing cells, suggesting a new hair loss treatment.
research Tannic Acid Accelerates Cutaneous Wound Healing in Rats Via Activation of the ERK 1/2 Signaling Pathways
Tannic acid helps wounds heal faster in rats by activating certain cell signals and reducing inflammation.
research Hormonal activity in commonly used Black hair care products: evaluating hormone disruption as a plausible contribution to health disparities
Common Black hair care products may affect hormone levels and potentially impact health, especially in reproductive and metabolic areas.
research Comparative study on seasonal hair follicle cycling by analysis of the transcriptomes from cashmere and milk goats
Cashmere and milk goats have different hair growth cycles and gene expressions, which could help improve wool production.
