Hair Model, 100x Life-Size

This item is composed of four different models on the same base: the first is a longitudinal section, 100x life-size, of the hair root. The other three models are cross sections, greatly enlarged, of the hair shaft, hair root and hair bulb. The use of contrasting colours makes it easy to identify all the different layers, such as external and internal root sheath, cuticle and cortex that make up the hair.
