research Examination of hair growth parameters in androgenetic alopecia in women using TrichoScan
TrichoScan is reliable for counting and measuring hair density but may not accurately assess hair types in women with hair loss.
research Limitations of Treatment-Induced Alopecia Grading Instruments in Evaluating Therapeutic Response
Current methods for grading hair loss from cancer treatment are not accurate enough and need improvement.
research 132 Genetics of Stress Hormone Concentrations in Hair of Healthy Nursery Pigs and Their Relationship with Back Test Responses
Pig hair cortisol levels are inheritable and linked to stress responses, which could help select for more resilient pigs.
research Simultaneous Quantification of Dexpanthenol and Resorcinol from Hair Care Formulation Using Liquid Chromatography: Method Development and Validation
Researchers created a reliable method to measure dexpanthenol and resorcinol in hair products.
research Critical study of hair growth analysis with computer-assisted methods
The Trichoscan system was found to be inaccurate for measuring hair growth, needing better software to be useful.
research Study of Hairfall through Cohen hair loss index with reference to different Mizaj
Hair loss patterns are linked to temperament and can help diagnose it.
research An Automatic AI‐Based Algorithm That Grades the Scalp Surface Exfoliating Process From Video Imaging. Application to Dandruff Severity and Its Validation on Subjects of Different Ages and Ethnicities
The AI device accurately grades scalp exfoliation and can help diagnose scalp disorders.
research Low quality of life and high HSS‐29 scores reflect the risk of loss to follow‐up: a study in patients with androgenetic alopecia
Low quality of life and high HSS-29 scores increase risk of losing patients during treatment.
research PRECISE Scale: a quantitative classification for androgenetic alopecia and its application to hair transplantation
The PRECISE scale helps estimate how many grafts are needed for hair transplant based on the severity of hair loss.
research Rethinking the classification of alopecia areata
The document concludes that a new system using the SALT score should replace the current alopecia areata classification for better accuracy in assessing severity and prognosis.
research 5α-Reductase activity in the human hair follicle concentrates in the dermal papilla
The enzyme that changes testosterone to a stronger form is mostly found in the part of the hair follicle called the dermal papilla.
research Human scalp hair: geometry, biochemistry, growth parameters and mechanical characteristics
A 6-group geometric classification of human scalp hair is more reliable and objective for testing than an 8-group system.
research Diagnostic and grading criteria for androgenetic alopecia using dermoscopy
New dermoscopic criteria accurately diagnose and grade the severity of hair loss in androgenetic alopecia.
research BH31 Dermoscopic analysis of patients with and without poor prognostic indicators in alopecia areata: a comparative study
Certain hair and scalp features can predict the severity of alopecia areata.
research The unit area trichogram in the assessment of androgen-dependent alopecia
The unit area trichogram is a reliable method to assess hair loss and treatment response in people with androgenic alopecia by measuring hair density and thickness.
research Methods of evaluating hair growth
Global photography and phototrichogram techniques are the best current methods for measuring hair growth.
research The Dermatology Life Quality Index (DLQI ) used as the benchmark in validation of 101 quality‐of‐life instruments: A systematic review
The DLQI is a key tool for measuring quality of life in dermatology.
research Measurement of hair growth
Scalp hair grows at 0.37 mm/day, forearm hair at 0.18 mm/day, and thigh hair at 0.30 mm/day, with no significant differences found in people with certain hair conditions.
research Validation of TrichoScan® technology as a fully-automated tool for evaluation of hair growth parameters
TrichoScan® is a reliable tool for measuring hair growth, providing quicker and more consistent results than manual methods.
research Hair Fall Count 60-second: Clinic-Based Modified Count Versus Home-Based Count
The clinic-based hair fall count method is accurate and reliable.
research [A longitudinal elasticity study of hair from the human head in forensic medicine].
The method effectively measures hair elasticity and could be useful in forensics.
research Exhaustive analysis of scalp hair regression: subjective and objective perception from initial hair loss to severe miniaturisation and drug-induced regrowth
Hair loss reduces hair thickness and coverage, but drug treatments mainly revive dormant hairs rather than reverse thinning; patients often undervalue their hair loss severity.
research Deep Hair Phenomics: Implications in Endocrinology, Development, and Aging
A new tool can analyze hair to detect changes due to hormones, genetics, and aging.
research Hair Follicle Classification and Hair Loss Severity Estimation Using Mask R-CNN
An intelligent system can classify hair follicles and measure hair loss severity with reasonable accuracy.
research A modified Sobel filter-based automated numerical algorithm enables immediate trichoscopic assessment of hair diameter diversity in male and female pattern hair loss
A new computer tool quickly measures hair thickness differences in people with common types of hair loss.
research The use of hair cortisol for the assessment of stress in animals
Hair cortisol is a reliable way to measure long-term stress in animals.
research Profiling steroid and thyroid hormones with hair analysis in a cohort of women aged 25 to 45 years old
The method can measure multiple hormones in women's hair and may help identify hormone-related health issues.
research Measurement and comparison of various androgen levels in women with severe acne, hirsutism, and androgenic alopecia
Women with severe acne, hirsutism, and androgenic alopecia often have higher levels of certain androgens, but the specific pattern can't be predicted just by looking at symptoms.
research Hair pull test: Evidence-based update and revision of guidelines
The normal range for the hair pull test is 2 hairs or fewer, and washing or brushing hair before the test does not affect the results.
