The invention relates to a technical method of aroma detection, and in particular, relates to a method for analyzing aroma components of a shampoo. A headspace solid phase microextraction method and a simultaneous distillation extraction method are respectively adopted for extracting volatile substances of a shampoo sample, quantitative and qualitative analysis of the shampoo sample is performed by a gas chromatography-mass spectrometer, and analysis results of the two methods are compared and combined to obtain analysis data; a phenomenon of loss of the measured volatile aroma components of a to-be-detected shampoo sample in the headspace solid phase extraction method can be effectively avoided; and at the same time, in the distillation extraction method, a thermal decomposition phenomenon of the measured volatile aroma components can be effectively avoided.
