Hair changes could indicate neurological diseases and help monitor treatment.
research ANALÝZA KORTIZOLU VO VLASOCH – BIOMARKER AKTIVÁCIE HPA OSI
Hair cortisol levels can effectively indicate long-term hormone activity.
research Assessment of hair density and caliber in white and Asian females with female pattern hair loss using folliscope
White females have higher hair density, while Asian females have thicker hair in hair loss cases.
research Environmental Influences on the Hair Follicle
Environmental factors like temperature and nutrition affect hair growth, with humans showing seasonal hair growth differences.
research A technique for more precise distinction between catagen and telogen human hair follicles ex vivo
Researchers developed a new method using methylene blue staining to more accurately identify the growth stage of human hair follicles.
research Diagnosis of hyperandrogenism: Biochemical criteria
The document concludes that accurate measurement of serum androgens is crucial for diagnosing hyperandrogenism.
research P187 : Folliscope analysis of temporal involvement in Korean women with female-pattern hair loss
Many Korean women with female-pattern hair loss have reduced hair density at the temples.
research The Comparative Potency of Hydrocortisone Analogs in Suppressing Growth of Hair in the Rat121From the Departments of Dermatology and Syphilology and of Anatomy, University of Michigan Medical School, Ann Arbor, Michigan.2Supported in part by research grants from the National Institutes of Health, United States Public Health Service (A-131 (C5)), the University of Michigan Memorial-Phoenix Project #145 and The Upjohn Company.
research New frontiers in human hair follicle (neuro‐)endocrinology
Human scalp hair follicles can produce and respond to several hormones, affecting hair growth and pigmentation.
research Identification of factors contributing to phenotypic divergence via quantitative image analyses of autosomal recessive woolly hair/hypotrichosis with homozygous c.736T>ALIPH mutation
Different hair fiber development might explain why hair loss severity varies in patients with a specific genetic mutation, and treatments that thicken hair could help.
research An isolated, implausibly large effect in a case-control study of digit ratio (2D:4D) and male androgenetic alopecia: Comment on Unal (J Cosmet Dermatol 2018;17(3):545-548)
Digit ratio likely doesn't predict male hair loss.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research Clinical Relevance of Hair Cortisol Measurement
Measuring cortisol in hair helps understand stress and manage related health issues.
research Within-person changes of cortisol, dehydroepiandrosterone, testosterone, estradiol, and progesterone in hair across pregnancy, with comparison to a non-pregnant reference group
Hormone levels in hair change during pregnancy, with progesterone increasing significantly compared to non-pregnant women.
research Soluble and insoluble collagen and elastin in the rat hair cycle
research Age- and sex-dependence of five major elements in the development of human scalp hair
Calcium and magnesium in hair increase with age and are higher in adult women.
research 1040 Photographing alopecia - How many pixels are needed for clinical evaluation?
Higher resolution images are needed to identify scarring and fine hair in alopecia.
research Correlation between Clinical Features, Biochemical Parameters, and Histopathological Findings in Women with Patterned Baldness: A Study from North India.
Patterned hair loss in women is linked to hormonal imbalances and biochemical changes, and should be evaluated for underlying health issues.
research Increased calcidiol level in redhaired people: Could redheadedness be an adaptation to temperate climate?
Redheaded people have higher levels of a vitamin D precursor, suggesting red hair may be an adaptation for better vitamin D synthesis in areas with less sunlight.
research Dorsal Skin Reactions of Hairless Dogs to Topical Treatment with Corticosteroids
Stronger corticosteroids cause more skin damage in hairless dogs, similar to effects in humans.
research Trichoscopic criteria of different stages of male pattern hair loss
Trichoscopy effectively distinguishes between severe and mild male pattern hair loss.
research Validity and Advantages of Three-Dimensional High-Frequency Ultrasound in Dermatological Evaluation
3D high-frequency ultrasound can help diagnose skin and hair conditions without invasive biopsies.
research Dilation of Multiple Eccrine Ducts as a Highly Specific Marker for Cicatricial Alopecia
Widened sweat ducts are a very specific sign of scarring hair loss.
research A Non-Invasive Hair Test to Determine Vitamin D3 Levels
The hair test for vitamin D could be a useful alternative to blood tests, providing a longer-term vitamin D status, but more research is needed.
research The determination of endogenous steroids in hair and fur: A systematic review of methodologies
research EEMCO Guidance for the in vivo Assessment of Skin Greasiness
The document recommends using both clinical evaluation and various measurement methods to assess skin greasiness, considering factors like temperature and hormones.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research Hair cortisol: an indicator of HPA activity in relation to environmental perception in New Zealand White rabbit.
Hair cortisol reliably indicates stress in rabbits.
research An Improved Method for the Histological Preparation of Single Hairs and Dust Samples—Morphological and Immunological Examination
