In comparative example 3, the radical scavenging ability of the composition was greatly reduced and the itching relieving score was still high after the hair dye was used, compared with example 4, only by reducing the amount of the refined bamboo vinegar. Compared with the example 4, the active ingredients in the curcumin derivative, the plant essential oil and the bamboo vinegar are not embedded, the free radical scavenging capacity of the composition is higher, but the itching relieving score after the hair dye is used is lower, which shows that the active ingredients can be slowly released by adopting the cyclodextrin for embedding, and the long-acting bacteriostasis and itching relieving effects are achieved. In conclusion, the method of example 4 can slowly release part of the components after hair dyeing, and simultaneously ensure strong capability of removing free radicals of scalp and good bacteriostatic and itching relieving effects.
