Zusammenfassung:	The invention relates to the field of biological detection, and provides a preparation method of a hair matrix standard substance, which comprises the following steps: uniformly mixing a matrix and hydrogel to prepare ink, adding a drug solution into the ink, uniformly mixing to prepare printing ink, and carrying out 3D printing on the printing ink to obtain the hair matrix standard substance, the hair matrix standard substance is prepared by using a 3D printing technology, and a medicine solution is uniformly dispersed in ink, so that the distribution state of a target toxic medicine in real toxic-related human body hair in the hair is close, and the concentration of the medicine in the hair matrix standard substance is clearer; according to the ink prepared by the invention, rheological characteristic parameters are limited, so that the physical characteristics of the ink are closer to analyzed hair samples in real cases; the matrix provided by the invention not only has a natural hair matrix, but also prov
