JP5610311B2 - Hair treatment or hair rinse containing transesterified oil - Google Patents

Description

  The present invention relates to a hair treatment or hair rinse (also referred to as “hair treatment or the like”).

  Conventionally, silicones are blended in hair treatments and the like for the purpose of imparting smoothness and gloss to hair (Patent Document 1).

  However, in general, once the silicones adhere to the hair, it is difficult to remove them even after shampooing. Therefore, if you continue to use hair treatments and hair rinses that contain silicones, silicones will gradually accumulate on the surface of the hair, resulting in a feeling of roughness and dryness on the hair, or medicinal ingredients of various hair treatment agents inside the hair There was a problem that it was difficult to penetrate.
