Curl-Retention-Test

Perfectly Styled for Any Weather

The curl retention test is used to determine the weather resistance of hairstyling products. To do this hair tresses are treated under standard conditions with the products to be tested and curled using suitable hair rollers. The curls are then put in a warm, humid climate and the elongation of the curl is measured at the start as well as after various measuring times.
