research Hair cortisol as a biomarker for mood in bipolar disorder: a pilot study
Hair cortisol may be a good indicator of recent mood in people with bipolar disorder.
research An Adult With Hair Loss! a Rare Case of Non-Classical 3β Hydroxysteroid Dehydrogenase (3β HSD) Deficiency
A woman's hair loss and other symptoms were due to a rare hormone deficiency treatable with steroids.
research Variations of scalp, pubic and axillary hair
Pubic hair is thicker than axillary and scalp hair, useful for forensic identification.
research O13: Interpretation of hair ethyl glucuronide inter-individual factors from large population dataset
Older age increases positive hair alcohol test results, and chest hair is a good alternative for testing; season affects results, with higher levels in winter.
research Measurement of cortisol in human Hair as a biomarker of systemic exposure
Hair cortisol can be used to measure long-term stress exposure.
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 Establishment of an evaluation method to detect drug distribution in hair follicles
Researchers developed a method to measure drugs in hair follicles and found that both water-loving and fat-loving drugs can be detected after being applied to the skin.
research 584 Transcriptomic analysis to identify protective dermal papilla signature in occipital scalp
The research found genes that may protect certain scalp cells from hair loss.
research 862 Defining the molecular signature of the hair follicle dermal sheath and its functional requirement for hair cycle progression during catagen
The hair follicle dermal sheath is essential for hair shedding and needs to communicate with the outer root sheath for normal hair growth cycles.
research Cyclic Alopecia and Abnormal Epidermal Cornification in Zdhhc13 -Deficient Mice Reveal the Importance of Palmitoylation in Hair and Skin Differentiation
The enzyme DHHC13 is essential for healthy hair and skin, and its deficiency leads to hair loss and skin problems.
research The combination of hair follicle-specific marker LHX2 and co-expressed marker can distinguish between sweat gland placodes and hair placodes in rat
LHX2, with other markers, can identify hair placodes in rats.
research Establishment of SV40T-transformed human dermal papilla cells and identification of dihydrotestosterone-regulated genes by cDNA microarray
Researchers created a cell line to study hair growth and found specific genes affected by dihydrotestosterone.
research Δ5-3β-Hydroxysteroid Dehydrogenase Activity in Sebaceous Glands of Scalp in Male-Pattern Baldness
research The disrupted balance between hair follicles and sebaceous glands inHoxc13‐ablated rabbits
Rabbits lacking the Hoxc13 gene show similar hair and skin issues to humans with ECTD-9, making them good for research on this condition.
research Dehydroepiandrosterone (DHEA) and Testosterone Concentrations in Human Hair after Chronic DHEA Supplementation
Chronic DHEA supplementation slightly increases testosterone in hair but stays within safe limits.
research Identification of androgen-regulated genes in SV40-transformed human hair dermal papilla cells
Hsc70 protein may influence hair growth by responding to androgens.
research 5 Dihydrotestosterone metabolism
Certain finger length ratios and body hair patterns may predict side effects from birth control pills in women.
research The validation of estradiol extraction and analysis from hair
Hair can reliably measure average estradiol levels over months in humans and monkeys.
research Correlations between dechlorane plus concentrations in paired hair and indoor dust samples and differences between dechlorane plus isomer concentrations in hair from males and females
Females have higher Dechlorane Plus in hair, while males have more in dorm dust.
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 Hair stress hormones in individuals with a recent suicide attempt experiencing a depressive episode
People who recently attempted suicide during depression showed signs of adrenal fatigue, but had higher DHEA levels around the attempt time.
research Evaluation of hair growth
The document concludes that measuring hair density, shaft diameter, growth rate, and anagen:telogen ratio is important for assessing hair growth treatments.
research Ligand‐independent Regulation of the hairless Promoter by Vitamin D Receptor†
Vitamin D receptor can control the hairless gene linked to hair loss even without vitamin D.
research Dab2 (Disabled-2), an adaptor protein, regulates self-renewal of hair follicle stem cells
Dab2 protein is crucial for hair follicle stem cell renewal and preventing early aging.
research Hair and Nail Cortisol as Biomarkers of Adolescent Stress: The Mental Health in the Moment Biosampling Protocol [Extended Data]
research Serum and hair steroid profiles and their associations with body composition in adolescence
Hair steroid profiling is a feasible, non-invasive alternative to serum analysis for assessing hormone levels and metabolism.
research Hair growth measurement using intradermal sulfur 35 cystine
The method accurately measures hair growth with minimal risk and is better than other methods.
research Disorders of hair
The document concludes that hair analysis is not good for assessing nutrition but can detect long-term heavy metal exposure.
research Assessment of hair re-growth and the correlation between hair cortisol and faecal glucocorticoid metabolite concentrations in captive wolves
Hair cortisol levels in wolves reflect stress and vary by season and body region.
