Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a shampoo composition, and more particularly, to a shampoo composition that is used to improve the suppleness of hair after shampooing,
This invention relates to a shampoo composition with excellent conditioning effects that imparts a rinsing effect such as smoothness and improves the softness of hair after drying by reducing calcium in the hair.

[Conventional technology and its problems]

Hair is easily damaged by external factors such as sunlight, heat, chemical treatments, and mechanical stimulation, and problems include fading, split ends, and deterioration in texture. In particular, when NoQ-manent wave treatment is performed, the hair becomes bulky and the texture deteriorates significantly due to the reduction treatment using thioglycolic acid, etc., and then the oxidation treatment using bromate, etc. It is being

In general, to improve the feel of your hair, use a rinse or treatment after shampooing, or cationize with shampoo? It has been attempted to incorporate conditioning agents such as rimers. However, the current situation is that hair treated with NOQ-manent wave treatment has not yet achieved sufficient improvement or recovery in feel.
