[0028] The above composition was prepared by mixing all the components in water and melting the lipophilic waxy material at 80° C. which was followed by homogenizing at a share rate of 2500 rpm, afterwards the composition was cooled down to 40° C. while mixing and pH was adjusted and the remaining water and fragrance was added.

[0029] The above composition was tested in a half side comparative test against a commercially available product in June 2019 Briogeo Curl Charisma. 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.
