Studysummary This study developed a new method using liquid chromatography-tandem mass spectrometry to measure multiple steroid hormones in hair, requiring significantly fewer strands than previous methods, with high accuracy and precision.

In a study by Hobo et al., a new LC-MS/MS method was developed to measure ten steroid hormones in 5 to 10 hair strands, demonstrating high accuracy (96.0-106.4% intra-assay and 96.9-104.9% inter-assay) and precision (4.8-10.6%). The method used a novel extraction solvent, improving cortisol extraction by about two-fold. It showed good linearity, acceptable matrix effects, and high recovery rates (94.1-108.3%) for the hormones. Applied to 6 healthy male volunteers, the method successfully measured 8 out of 10 steroids, suggesting its potential for evaluating chronic stress and alopecia-related conditions with minimal sample requirements. The method's sensitivity and low invasiveness make it suitable for large-scale studies and could clarify the relationship between steroid hormone levels and hair loss diseases.

research Hair as a Retrospective Calendar of Cortisol Production—Increased Cortisol Incorporation into Hair in the Third Trimester of Pregnancy

501 citations , October 2008 in “Psychoneuroendocrinology”

This study suggests that cortisol measured in human hair can effectively reflect increased production for up to six months, but its retrospective accuracy may be limited due to rapid decline in levels.
