Abstract:
1. A method for lanthionizing keratin fibers to achieve relaxation of said keratin fibers comprising: (i) applying a pretreatment composition to said keratin fibers, wherein said pretreatment composition comprises at least one reducing agent chosen from thioglycolates for a sufficient period of time to reduce at least one keratin bond in said keratin fibers; (ii) rinsing said keratin fibers; (iii) generating hydroxide ions in at least one solvent, wherein said step of generating comprises including at least one hydroxide compound in said at least one solvent; (iv) applying a composition comprising said generated hydroxide ions to said keratin fibers for a sufficient period of time to lanthionize at least one of said keratin fibers; (v) heating said keratin fibers; and (vi) terminating said lanthionization when said keratin fibers are relaxed.
