Proteins are eluted from hair in hair care processing such as shampooing, hair styling, hair nourishing, and hair dyeing. In hair care, it was considered necessary to suppress protein elution from hair. A protein dissolution inhibitor containing collagen derived from fish skin, The collagen has a circular dichroism (CD) spectrum having a negative maximum at 207 to 210 nm, and a protein elution inhibitor that exhibits a positive value at 200 nm substantially eliminates protein elution from hair in hair care treatments. All can be suppressed. This is not the protection of the so-called cuticle but the protection of the hair by forming a new film on the hair surface. [Selection figure] None |
