Abstract
Experiments are conducted to obtain the comparative performance data at high temperature and humidity on some commercial hair spray resins. The quantitative evaluation of the hair-setting ability of the resin was made by “Curl Retention Test”, whareas the stickiness of the resin was meaured by using a Sward Rocker Hardness Meter. It was found that the test results were affected by the type of the resin as well as the kind of the neutralizer used.
