Therefore, the hair of 10 volunteers were washed with a commercially available shampoo under the Brand Goldwell and hair is dried with a hair drier and equal amounts of the products were applied to each half side and hair was styled by hair dresser. Hair dressers were asked to evaluate the following parameters in a scale of 1 to 5, wherein 1 is bad, 2 is not good, 3 is acceptable, 4 is good and 5 is very good. The following results were obtained. The numbers represent the average of 10 tests.
