Research
960-990 / 1000+ results research Circulating testosterone and feather-gene expression of receptors and metabolic enzymes in relation to melanin-based colouration in the barn owl
Barn owls with smaller black spots have higher testosterone levels, which might be due to genetic effects on hormone regulation rather than hormone effects on coloration.
research Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography
Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.
research Diagnostic Accuracy of Polarized and Ultraviolet Fluorescence-Induced Dermoscopy in Scarring and Nonscarring Alopecias: a Retrospective Observational Multicentric Study
UVF-dermoscopy is a useful tool for accurately diagnosing types of alopecia, especially in people with lighter skin.
research Investigation of Hair Diseases Accompanying Bitemporal Alopecia: An Observational Cross‐Sectional Study
Bitemporal alopecia often occurs with other hair conditions and can help predict and monitor these issues.
research Differential effects of melatonin as a broad range UV-damage preventive dermato-endocrine regulator
Melatonin protects skin against UV damage by regulating various cellular processes.
research Developmental and environmental determinants of hair steroids in children from birth to two years postnatally: A comprehensive analysis
Hair analysis can effectively assess long-term hormone activity in young children.
research New colour accessibility policy for The Society’s journals
The Society's journals now have a policy to make colors in their content accessible to people with color blindness.
research The localisation and characterisation of insulin-like growth factor-I receptors and the investigation of melatonin receptors on the hair follicles of seasonal and non-seasonal fibre-producing goats
Goat hair follicles have insulin-like growth factor-I receptors that might affect hair growth, but no melatonin receptors were found.
research On the Effect of Estrogen Receptor Agonists and Antagonists on the Mouse Hair Follicle Cycle
β-estradiol slows hair growth in mice.
research `Cyclic alopecia' inMsx2mutants: defects in hair cycling and hair shaft differentiation
Msx2-deficient mice experience irregular hair growth and loss due to disrupted hair cycle phases.
research Morphological analysis of in vitro human hair growth
Human hair follicles can grow and stay healthy for up to 8 days in a lab setting.
research Cognitive testing of a survey instrument for self-assessed menstrual cycle characteristics and androgen excess
The survey helps identify menstrual irregularities and excess male hormones, aiming to detect conditions like Polycystic Ovary Syndrome.
research UV-A조사에 의한 반영구염색모발의 형태학적 변화
UV-A radiation significantly damages semi-permanent dyed hair.
research Identification of Telogen Markers Underscores that Telogen Is Far from a Quiescent Hair Cycle Phase
Telogen is an active phase with important biological processes, not a resting phase.
research A glutathione-dependent control of the indole butyric acid pathway supports Arabidopsis root system adaptation to phosphate deprivation
Glutathione helps Arabidopsis roots adapt to low phosphate by regulating a specific growth pathway.
research Comparative study of trichoscopic versus digital folliscopic findings of Telogen Effluvium
Trichoscopy is easier and quicker than folliscopy for diagnosing telogen effluvium.
research Lichen planopilaris epidemiology: a retrospective study of 80 cases
Lichen planopilaris mostly affects women with fair skin and can look different on each person, needing early treatment to prevent hair loss.
research Hormonal fluctuations under systemic stress: Investigating adolescent hair cortisol trends before and during the COVID-19 pandemic.
research Associations between season, climate, and pediatric alopecia areata flares in Providence, Rhode Island
Hair loss in children with alopecia areata is more common in winter and linked to climate factors like air pressure and sunlight.
research Results in a ‘Flash’: Recognizing Misleading Clinical Photography
Be critical of before-and-after photos in dermatology to avoid misleading impressions.
research Determination of estradiol and progesterone concentrations in human scalp hair
Hair levels of estradiol and progesterone are higher in premenopausal than postmenopausal women, but the difference isn't statistically significant, indicating the need for a better measurement method.
research Field melanin mapping of the hairless scalp
The study found a specific pattern of uneven melanin distribution on balding scalps that could help understand skin diseases caused by light exposure.
research The cycling hair follicle as an ideal systems biology research model
The hair follicle is a great model for research to improve hair growth treatments.
research Towards a “free radical theory of graying”: melanocyte apoptosis in the aging human hair follicle is an indicator of oxidative stress induced tissue damage
Oxidative stress causes hair to gray by damaging and killing pigment cells.
research Estrogen Leads to Reversible Hair Cycle Retardation through Inducing Premature Catagen and Maintaining Telogen
Estrogen can temporarily slow down hair growth but this can be reversed.
research Phosphatidylinositol‐specific phospholipase C2 functions in auxin‐modulated root development
A protein called PLC2 is important for the growth and development of plant roots influenced by auxin.
research Chemical and photo-oxidative hair damage studied by dye diffusion and electrophoresis.
Chemical treatments and light exposure damage hair proteins.
research Nonsynchronized segmented heterochromia in black scalp hair
A 14-year-old girl's black hair showed unique color changes, suggesting early greying.
research Analysis of the expression pattern of the carrier protein transthyretin and its receptor megalin in the human scalp skin and hair follicles: hair cycle-associated changes
The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.
