Washing hair with shampoo results in an accumulation of shampoo components in the hair. Hair of individuals using different shampoos can be distinguished by analysis of shampoo residues. A method for extraction and analysis of such residues is presented. The hair is extracted using a methanol/water mixture, and the extract is analyzed by reverse-phase high-pressure liquid chromatography (HPLC). The detector system consists of two ultraviolet (UV) detectors connected in series. The method is nondestructive to hair and is sensitive enough to be applied to a single hair 5 to 10 cm in length. Residues from hair balsams are analyzed by this technique as well. The use of this method in forensic science examination of human head hair is demonstrated.
用洗发水洗头会导致头发中积累洗发水成分。通过分析洗发水残留，可以区分使用不同洗发水的人的头发。本文介绍了一种提取和分析此类残留的方法。使用甲醇/水混合物提取头发，提取物通过反相高压液相色谱法（HPLC）进行分析。检测系统由两个串联的紫外（UV）检测器组成。该方法对头发无损，灵敏度足以应用于长度为5至10厘米的单根头发。该技术也可用于分析发香脂的残留。本文展示了该方法在人类头发法医学检验中的应用。
