research Hair elemental status as a diagnostic parameter: achievements, challenges and opportunities
Analyzing hair for its elemental makeup can be useful for diagnosis, but there are still challenges and room for improvement.
research Comparative Evaluation of Hair Density and Grouped Hair Unit Pattern between Androgenetic Alopecia and Normal Scalp
People with androgenetic alopecia (AGA) have lower hair density and more single-hair units compared to those with normal scalps.

Two methods reliably measure scalp area and hair count.
research Peer Review #2 of "Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis (v0.1)"
The research found that people's hair proteins vary, especially by ethnicity and body part, which could help identify individuals in forensic science.
research Standardization of Trichotillometer
Trichotillometry can measure hair plucking force, aiding alopecia treatment evaluation.

The hr gene is crucial for skin and hair health, with mutations causing hair disorders.
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 Dermoscopic findings of alopecia areata in dark skinned individuals: An analysis of 116 cases
The study concluded that yellow dots are a common and useful sign for diagnosing alopecia areata in dark-skinned individuals and may indicate the severity of the condition.
research Changes in the Molecular Structure of Hair in Insulin-Dependent Diabetes
Insulin-dependent diabetes alters hair's molecular structure, making it useful for studying diabetes effects.
research Inverse correlation between vitamin D and CRP levels in alopecia areata: A pilot study
Lower vitamin D levels are linked to higher CRP levels in people with a type of hair loss called alopecia areata.
research 441 Anti-melanoma gene signature in dermal sheath fibroblasts from scalp hair follicles in Recessive Dystrophic Epidermolysis Bullosa (RDEB)
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 Scalp hair sweating as a predictor of hair cortisol level in human compared to obesity and other confounders
Scalp hair sweating is a significant predictor of hair cortisol levels.
research Cuticle damage and the tensile properties of human hair
Cuticle damage doesn't affect hair's tensile strength; the cortex is responsible for it.
research New insights into human hair: SAXS, SEM, TEM and EDX for Alopecia Areata investigations
Alopecia Areata causes significant structural and compositional changes in hair.
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 Staining of human skin with RGB trichrome unveils a proteoglycan-enriched zone in the hair dermal sheath
A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.
research Hair cortisol as a novel biomarker of stress
Hair cortisol can be a reliable way to measure long-term stress.
research Scalp Dermoscopy or Trichoscopy
Trichoscopy is a quick, noninvasive method to diagnose hair and scalp disorders, often reducing the need for biopsies.

Females with 5 alpha-reductase-2 deficiency have less body hair, no acne, normal fertility, and delayed menarche.
research Self-Assessment examination of the American Academy of Dermatology
research Evaluating the accuracy of patient-reported hair outcomes versus trichometric measurements in PRP therapy
Patient-reported hair improvements align with actual hair density changes, not hair width.
research Determination of estradiol and progesterone concentrations in human scalp hair
Hair levels of estradiol and progesterone are higher in premenopausal than postmenopausal women, but the difference isn't statistically significant, indicating the need for a better measurement method.
research Hair cortisol and other hair analytes decline with storage over a one-year period: A systematic, within-subject investigation
Hair analytes decrease with storage, so analyze within six months.
