Figure 3. Split graphs comparing the effects of shampoo and conditioner on internal hair structures.

In (A), the untreated sample is compared with the shampooed sample. In (B), the untreated sample is compared with the conditioned sample. In (C), the untreated sample is compared with the sample with both shampoo and conditioners applied. There were no major changes observed in signals of interest.
