TLDR Body hair isn't a good substitute for scalp hair in steroid analysis.
The study developed and validated an LC-MS/MS method for quantifying seven steroid hormones in hair, revealing that cortisone and testosterone concentrations were higher in body hair than scalp hair. Pigmentation did not significantly affect steroid concentrations, and no correlation was found between steroid levels in hair and nails. The study concluded that body hair is not a suitable alternative to scalp hair for steroid analysis due to weak correlations and varying growth rates. The research involved 38 subjects and highlighted the need for matrix-dependent value ranges for interpreting hair and nail steroid levels.
