Sažetak
Hair analysis provides reliable information on long-term nicotine exposure, depending on hair length. The ability of hair to preserve substances such as nicotine incorporated into its shaft may be compromised by the chemical treatment of hair that can damage the structure of the hair and affect the accurate detection of nicotine in it. The aim of this study was to investigate whether different hair chemical treatments (bleaching, dyeing, and wash-out colouring) reduce hair nicotine levels. Hair nicotine content was determined in non-treated and chemically treated hair segments in 20 samples using the headspace solid-phase microextraction (HS-SPME) method followed by gas chromatography-mass spectrometry (GC-MS). Nicotine levels were lower in chemically treated hair in comparison to hair without treatment. The study also showed that different types of chemical treatment had different effect on hair nicotine levels. While bleaching influenced nicotine levels the most (23–88% decrease), certain other types of hair treatment (wash-out coloration) did not have a significant effect (less than an 8% decrease). Dying reduced hair nicotine levels up to 40%, depending on the colouring formula. Given that there is a limited number of similar studies, this one could provide a direction for other studies concerning the influence of diverse chemical treatments on drug levels in hair. These data also suggest that the effect of chemical cosmetic treatment on hair has to be taken into account when interpreting results of drug abuse standardly analysed in hair, which are mainly basic compounds such as nicotine.
