research DHT and E2 synthesis-related proteins and receptors expression in male yak skin during different hair follicle stages
Male yak hair growth is influenced by DHT synthesis, which is promoted by 5α-red1 and AR during growth phases, while E2 may inhibit growth through ERα.
research Sensitive Quantitative In Vivo Assay for Evaluating the Effects of Biomolecules on Hair Growth and Coloring Using Direct Microinjections into Mouse Whisker Follicles
The new "whisker follicle microinjection assay" can test how different biomolecules affect hair growth and color.
research Integral characterization of normal and alopecic hair at different degeneration stages by in-situ visible and chemical imaging
Alopecic hair has more irregular structures and chemical changes than normal hair, reducing its strength.
research Elemental content of anagen hairs in a normal Caucasian population studies with proton induced X-ray emission (PIXE).
PIXE is an effective method to analyze hair's elemental composition.
research The usefulness of dermoscopy in canine pattern alopecia: a descriptive study
Dermoscopy is useful for diagnosing hair loss patterns in dogs.
research Hair follicle testing-an alternative to urinalysis for drug abuse screening
Hair follicle testing is more reliable and effective for drug screening than urinalysis.
research Human hair morphology: a scanning electron microscopy study on a male Caucasoid and a computerized classification of regional differences.
Hair varies in size and features depending on body region.
research Hair anatomy for the clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research Development and pilot-testing of the Alopecia Areata Assessment Tool (ALTO)
The Alopecia Areata Assessment Tool (ALTO) effectively identifies alopecia areata from other hair loss types but needs more validation.
research The Mineralization of Hair Follicle Tissue
Mineral deposits form in hair follicles after skin injury, faster in rats given DHT.
research Steroid 17-Hydroxyprogesterone in Hair Is a Potential Long-Term Biomarker of Androgen Control in Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency
Measuring 17-hydroxyprogesterone in hair can help monitor androgen levels in people with congenital adrenal hyperplasia.
research 1451 THE ASSOCIATION BETWEEN MALE PATTERN BALDNESS AND SECOND TO FORTH FINGER RATIO WITH PROSTATE CANCER- A PROSPECTIVE COHORT STUDY
Male pattern baldness may predict prostate cancer risk.
research Dermatoscopic Findings in Androgenetic Alopecia
Trichoscopy helps diagnose and track treatment for hair loss in men and women.
research 584 Dandruff is associated with perturbations of hair follicle immune privilege, and the infundibular and epidermal immune microenvironment
Dandruff is linked to changes in the immune system of hair follicles and skin.
research The place of B‐mode ultrasonography, shear‐wave elastography, and superb microvascular imaging in the pre‐diagnosis of androgenetic alopecia
B-mode ultrasonography and shear-wave elastography can help predict androgenetic alopecia early.
research The determination of endogenous steroids in hair and fur: A systematic review of methodologies
research Spatial Probing of the Properties of the Human Hair Surface Using Wilhelmy Force Profiles
Human hair surface varies in wettability, showing daily and monthly patterns.
research Fabrication and Magnetic Characterization of Cobalt Antidot Arrays: Effect of the Surrounding Continuous Film
Dermoscopy helps dermatologists diagnose different types of hair loss accurately without always needing a biopsy.
research Diagnosis of breast cancer by X-ray diffraction of hair
X-ray diffraction of hair might help detect breast cancer non-invasively.
research Hyperandrogenism and woman's sexual function
Hyperandrogenism did not affect sexual function in young women.
research 臨床研究における毛髪コルチゾールの有用性と限界
Hair cortisol can measure chronic stress but has inconsistent results.
research Analysis of quality of life and depression in patients with androgenetic alopecia or alopecia areata
Alopecia negatively affects quality of life and mental health.
research Hair cortisol concentrations in mental disorders: A systematic review
People with depression often have higher hair cortisol levels, while those with PTSD tend to have lower levels, but more research is needed to understand this fully.
research Automated digital image analysis (TrichoScan) in male patients with androgenetic alopecia; comparison with manual marking of hairs on trichoscopic images
TrichoScan needs optimization as it underestimated hair density by 38.9% compared to manual counting.
research Vitamin D Status Assessment: Lack of Correlation between Serum and Hair 25-Hydroxycholecalciferol Levels in Healthy Young Adults
Vitamin D levels in hair don't match those in blood, so hair isn't a reliable indicator of Vitamin D status.
research Clinical and histological challenge in the differential diagnosis of diffuse alopecia: female androgenetic alopecia, telogen effluvium and alopecia areata – part I
Diagnosing hair loss disorders needs clinical, dermoscopic, and histological differences, and checking menstrual cycle, weight changes, drug therapy, and nail changes.
research Relationship of Hair Cortisol Concentration With Perceived and Somatic Stress Indices: Cross-Sectional Pilot Study
Hair cortisol concentration may reflect some physiological stress but doesn't strongly correlate with perceived stress.
research (Un)targeted Scanning of Locks of Hair for Drugs of Abuse by Direct Analysis in Real Time–High-Resolution Mass Spectrometry
A new method can quickly and accurately detect drugs in hair.
research Is there a relationship between alopecia and anthropometric indicators? Modern scientific view
Anthropometric measurements like weight and BMI may help identify alopecia risk groups.
