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 rwSALT: a regrowth-weighted SALT score providing direct pixel-level measurement rather than visual estimation
rwSALT provides precise hair regrowth measurement from scalp photos.
research A Segmental Approach to Scoring Hair Density from Global Images: Introducing the Scalp Coverage Scoring Method for Clinical Trials and Practice
The Scalp Coverage Scoring method reliably measures hair density from images.
research Recent Findings with Computerized Methods for Scalp Hair Growth Measurements
TrichoScan effectively measures hair growth improvements in people using minoxidil.
research TrichoScan: combining epiluminescence microscopy with digital image analysis for the measurement of hair growth in vivo.
TrichoScan accurately measures hair growth and showed improved hair counts and thickness after finasteride treatment.
research Quantitative Studies on Human Hair Growth(I). Fundamental Measurements and the Evaluation of Hair Growers.
Hair grows slower and thinner with age, but a test tonic improved growth in alopecia subjects.
research Secondary structure estimation and properties analysis of stretched Asian and Caucasian hair
Stretching damages Caucasian hair's structure more easily than Asian hair.
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 A clinico-trichoscopic analysis of hair density and diameter variability in relation to severity grading of female pattern hair loss
Trichoscopic measurements help determine the severity of female pattern hair loss.
research Reply
The authors defended their methods for measuring hair density and caliber, emphasizing the need for consistent photography and manual counting for accuracy in evaluating hair loss treatments.
research Phototrichogram Analysis of Japanese Female Subjects with Chronic Diffuse Hair Loss
Phototrichogram and hair diameter measurements are effective, noninvasive ways to assess hair growth and detect early hair loss, with the most common pattern being reduced hair density.
research Clinical and instrumental characterization of hair and scalp aging in nonbalding Caucasian women
Aging significantly affects the hair and scalp of nonbalding Caucasian women, with changes that differ from male pattern baldness.
research Androgenetic alopecia. Modelling progression and regrowth
AGA causes hair loss through follicle miniaturization and hair cycle changes; regrowth depends on anagen initiation in kenogen follicles.
research Patient-reported outcomes, provider-reported outcomes, and physiologic parameters after gender-affirming hormone treatment in Canada: a systematic review
Gender-affirming hormone treatments need better patient-focused outcome measurements and standardized data collection.
research A Comparison of Reticle Size to Determine Follicular Unit Density in Hair Restoration
Smaller reticle sizes are as accurate as the standard size for measuring hair density in hair restoration.
research What women want - quantifying the perception of hair amount: an analysis of hair diameter and density changes with age in caucasian women
Caucasian women's hair appears thickest in their 20s, with perceived thinning after mid-30s due to both decreasing density and diameter.
research The changing patterns of hair density and thickness in South Korean women with hair loss: clinical office-based phototrichogram analysis
South Korean women with hair loss have lower hair density and thickness compared to healthy women.
research Follicular Density and Ratios in Scarring and Nonscarring Alopecia
Nonscarring alopecia has higher hair density than scarring alopecia, and hair density can help diagnose the type of alopecia.
research Bone Mineral Density is Unaltered in Women with Polycystic Ovary Syndrome
Women with PCOS have similar bone density to healthy women, but those who are obese have higher bone density at some body sites.
research The long-term effect of specific type II 5alpha-reductase inhibition with finasteride on bone mineral density in men: results of a 4-year placebo controlled trial.
Finasteride does not harm men's bone health.
research Reliability and Validity of a Photographic Method for Measuring Facial Hair Density in Men
The photographic method for measuring facial hair density is reliable and valid but needs further testing on different hair densities and skin colors.
research Solubilities of Flutamide, Dutasteride, and Finasteride as Antiandrogenic Agents, in Supercritical Carbon Dioxide: Measurement and Correlation
Flutamide, dutasteride, and finasteride dissolve differently in supercritical carbon dioxide, with dutasteride dissolving the least.
research Lipid Profile, Atherogenic Index of Plasma, and Anthropometric Measurements Among Osteoporotic Postmenopausal Sudanese Women: Possible Risk for Cardiovascular Disease
Osteoporotic postmenopausal Sudanese women have a high risk of cardiovascular disease.
research Electronic States of Epigallocatechin-3-Gallate in Water and in 1,2-dipalmitoyl-sn-glycero-3-phospho-(1′-rac-glycerol) (Sodium Salt) Liposomes
EGCG shows strong electron transfer interactions when bonded to DPPG lipids.
research Analysis of quantitative changes in hair growth during treatment with chemotherapy or tamoxifen in patients with breast cancer: a cohort study
Chemotherapy causes hair loss starting soon after treatment begins and recovers about 3 months after ending, while tamoxifen does not significantly affect hair growth.
research Effects of Reducing Hair Damage by Permanent Wave Reductants Added Glycerin or Hyaluronic Acid
Adding 2% glycerin or hyaluronic acid to permanent wave treatments reduces hair damage, with hyaluronic acid being more effective.
