The method effectively identifies banned substances in hair loss and skin disease cosmetics.
research SERUM-CONCENTRATIONS OF Dehydroepyandrosterone-sulfate IN MEN WITH ANDROGENETIC ALOPECIA
Men with hair loss don't necessarily have higher levels of the hormone DHEA-S, but this hormone tends to decrease with age.
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 TrichoScan
TrichoScan accurately measures hair growth and loss, showing increased hair counts and thickness with treatment.
research The Predictive Value of Midscalp Hair Density and Terminal Hair Percentage in the Severity Evaluation of FPHL Assessed by Trichoscan in a Sample of Chinese Population
Midscalp hair density and terminal hair percentage are good indicators of female pattern hair loss severity.
research Cutaneous hydroxystereoid dehydrogenases and rat-hair-cycle
Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.
research Applications of Hair as a Record of Systemic Exposure to Cortisol
Hair cortisol content can indicate cortisol exposure and varies with age, puberty, and BMI in youth.
research Hormones and Hair Growth: Variations in Androgen Receptor Content of Dermal papilla Cells Cultured from Human and Red Deer (Cervus Elaphus) Hair Follicles.
Human hair growth is influenced by androgen hormones, and red deer mane follicles have similar hormone receptors.
research Daily Circle of Calcium Concentration in Hair Observed by X-ray Fluorescence Analysis
Hair can show daily calcium changes, linked to body calcium levels and influenced by hormones, and can help assess calcium metabolism issues.
research Hair: Scalp Hair Growth Evaluation Methods
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.
