Curl Drop Test
If you want to show the extent of style hold created by your styling product, then you might consider performing a style retention test (also known as a curl drop or curl droop test). This test can also be used to investigate the humidity resistance of styling treatments.
Image analysis is used to assess the longevity of hair curls in the presence of elevated humidity conditions. High quality photographs show the curl integrity as a function of time.
