Chemical Straightening as a Source of Analytical Variability in Hair Testing: A Dual‐Analyte Case Report

Drug Testing and Analysis, Volume 18, Issue 6, Page 771-776, June 2026.
Permanent chemical hair straightening was associated with analyte‐dependent changes in hair concentrations, showing increased endogenous GHB levels and decreased alprazolam concentrations after treatment. These results suggest that chemical hair straightening procedures may influence hair concentrations and should be considered when interpreting hair ...
