Claim:
1. A method for achieving a desired level of curl in hair comprising: (a) applying to the hair one or more relaxing agents at an alkaline pH, wherein at least one of the relaxing agents is an alkali metal containing hydroxide; and (b) applying to the hair an active agent of Formula II: wherein Z is a linker or is absent and the linker is not a polymer; m and n are each an integer independently selected from 1-6, and the sum of m+n is equal to or greater than 2; B is a functional group capable of forming a covalent bond with a nucleophile, and B is independently selected from the group consisting of: wherein R is independently selected from the group consisting of hydrogen, C 1-6 alkyl groups, aryl groups, or an ionizable functional groups and Z′ is oxygen (O), NH or is absent, and G is carbon (C) and g is 1, or G is sulfur (S) and g is 2; A is an ionizable functional group independently selected from the group consisting of: —COOH, —SO wherein the active agent is present in an effective amount to retain a level of curl (percent curl retention) in the treated hair in the range of about 0-99%, compared to the amount of curl in the hair prior to step (a); and wherein steps (a) and (b) are performed simultaneously.
