An in house consumer test was conducted to determine whether consumers can see a significant difference in vibrancy when asked to compare hair switches washed 40 times (equivalent to 12 weeks) with the TRESemmé Colour Revitalise shampoo and conditioner compared to non-conditioning shampoo.
Hair switches were washed 40 times and a paired comparison test with 24 panellists was run, showing each panellist 6 pairs of switches (total 144 assessments) and asking them to assess which had more vibrancy.

RESULTS:

The vibrancy data was collected after 40 wash cycles.
