Claims8
A composition for the permanent waving of human hair, comprising:
- (A) at least one reducing component in an amount effective for the permanent waving of human hair,
- (B) an effective amount of at least one compound selected from the group consisting of C.sub.3 -C.sub.6 -alkanediols, ethers thereof, and mixtures thereof, and
- (C) 0.5 to 10% by weight of an alkalizing compound, wherein said alkalizing compound is ammonium carbamate, calculated based on the weight of the total composition.
A method for permanent waving of human hair which comprises applying to the hair an effective amount of a reducing composition comprising a permanent waving effective amount of a reducing component, an effective amount of at least one compound selected from the group consisting of C.sub.3 -C.sub.6 -alkanediols, ethers thereof, and mixtures thereof, and about 0.5 to about 10% by weight ammonium carbamate as an alkalinizing compound.
A composition for the permanent waving of human hair, consisting essentially of:
- (A) at least one reducing component in an amount effective for the permanent waving of human hair;
- (B) a carrier or penetrating agent comprising at least one compound selected from the group consisting of C.sub.3 -C.sub.6 -alkanediols, ethers thereof, and mixtures thereof,
- (C) 0.5 to 10% by weight of ammonium carbamate, calculated based on the weight of the total composition;
- and
- (D) water.
