research Assessing Dihydrotestosterone-Induced Skin Alterations in C57BL/6 Mice: Implications for Androgenetic Alopecia through High-Resolution Ultrasound Imaging
DHT causes thicker and less elastic skin, linked to hair loss.
research High‐frequency ultrasonography of the scalp: A comparison between androgenetic alopecia and healthy volunteers
High-frequency ultrasound can effectively visualize and assess hair loss.
research Distribution of Human Hair in Follicular Units
The research found that for a typical hair density, about 11 square centimeters of donor scalp is needed to get 800 hair grafts for transplantation.
research Hair diameter diversity: a clinical sign reflecting the follicle miniaturization.
Different thicknesses of hair strands can indicate the severity of hair thinning.
research Standardization of Trichotillometer
Trichotillometry can measure hair plucking force, aiding alopecia treatment evaluation.
research The Histology of Keratin Fibers
research Follicular miniaturization in female pattern hair loss: clinicopathological correlations
Hair loss severity relates to increased miniaturization in female pattern hair loss.
research An Automated Approach Towards Digital Photo-Trichogram for Hair Fall Diagnosis
Researchers developed a computer system to automatically diagnose hair loss by analyzing scalp images.
research ISID0192 - Three-dimensional ultra-high frequency ultrasound facilitates image processing to visualize microstructural changes of hair follicles and detects distinct disease phases of alopecia areata
3D-ultrasound can non-invasively detect and predict alopecia areata phases and outcomes.
research Analysis of Gene Expression in Isolated Single Hair Follicles: An Approach Using Semiquantitative Reverse-Transcriptase—Polymerase Chain Reaction
Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.
research Response to the article, “Evaluation of standardized scalp photography on patient perception of hair loss severity, anxiety, and treatment,” by Pathoulas et al
Combining scalp photos with hair density and caliber measurements gives a more accurate assessment of hair loss.
research Evaluation method of the degree of hair damage. (I). Measurement of tensile strength of human hair by "the multi-point tension test method".
The method accurately measures hair damage and strength, revealing effects of cosmetics and metal correlations.
research Hair counts in scalp biopsy of males and females with androgenetic alopecia compared with normal subjects
AGA patients have fewer hairs and smaller follicles; T:V ratio above 4:1 may indicate AGA.
research The Importance of Measuring Hair Density in the Diagnosis and Treatment of Hair Loss
Measuring hair density is crucial for diagnosing and treating hair loss.
research Patient-Based Ratio Method for Permanent Zone Donor Area Calculation in Hair Transplant
A new method helps ensure long-lasting hair transplant results by accurately calculating the donor area.
research Clinical and Trichoscopic Graded Live Visual Scale for Androgenetic Alopecia
Trichoscopy is crucial for diagnosing and managing androgenetic alopecia, showing increased vellus hairs, empty follicles, and fibrosis with severity.
research Epidemiology of hirsutism among women of reproductive age in the community: a simplified scoring system
A simplified scoring system can effectively diagnose hirsutism in Chinese women of reproductive age.
research Morphological and morphometric study of the androgenetic alopecic scalp using two- and three-dimensional analysis comparing regional differences
The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.
research Evaluation of hair follicles as a surrogate tissue for pharmacodynamics response in xenograft tumors
Hair follicles can be used to quickly assess drug effects in cancer treatment.
research [An immunohistochemical study on the normal human skin using an anti-hair keratin monoclonal antibody (HKN-2)].

Three new techniques simplify and improve the preparation of tissue samples for skin cancer surgery.
research The Microanatomy of Human Skin in Aging
Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.
research 48799 Defining Perceptual Thresholds for Hair Density Changes: A Study of Dermatologist Perceptions
Dermatologists can detect smaller hair density changes than previously thought.
research Microscopy of the hair and trichogram
Hair microscopy is a useful and affordable way to diagnose hair disorders.
