Description

  The present invention relates to a hair conditioning composition containing an acrylic copolymer having an oil-soluble t-butyl group. More specifically, the present invention relates to a smoothness at the time of washing, a glossy feeling and a firmness and firmness to the hair. The present invention relates to a comb-like hair conditioning composition that is excellent in imparting hair and is not stiff and supple.

Hair is damaged in various ways by perms, coloring, use of shampoos and dryers, air pollution, and strong sunlight in summer. Hair conditioning compositions such as hair rinses, hair treatments, and hair packs protect hair from damage caused by these various factors, repair the damage, give the hair shine, firmness and firmness, and make it supple and smooth. It is given. In order to express these effects, conventionally, hair conditioning compositions can be blended with high molecular compounds, oils, proteins, amino acids, cosmetic ingredients such as plant extracts, etc., or a combination thereof.
