1. A process of treating hair to provide a protective effect for the hair to improve the quality of the hair comprising applying to the hair a composition comprising in a cosmetic vehicle selected from the group consisting of water, alcohol, a hydroalcoholic solution, a gel and an emulsion of quaternized polymer having recurring units of the formula ##STR75## wherein R is lower alkyl or --CH2 --CH2 OH;

  • R'"'"' is alkyl, cycloalkyl or aralkyl containing a maximum of 20 carbon atoms, or R and R'"'"' together with the nitrogen atom to which they are attached form a heterocycle capable of containing a heteroatom other than nitrogen;

    A is a divalent group selected from the group consisting of(1) o-, m- or p-xylylidene of the formula ##STR76## (2) ##STR77## wherein x, y and t are whole numbers ranging from 0 to 11 such that the sum (x+y+t) is greater than or equal to 0 and lower than 18, and E and K represent hydrogen or alkyl having less than 18 carbon atoms,(3) --(CH2)n --S--(CH2)n --,(4) --(CH2)n --O--(CH2)n --,(5) --(CH2)n --S--S--(CH2)n --,(6) --(CH2)n --SO--(CH2)n --,(7) --(CH2)n --SO2 --(CH2)n --and(8) ##STR78## wherein n is equal to 2 or 3;

    B represents a divalent group selected from the group consisting of(1) o-, m- or p-xylylidene of the formula ##STR79## (2) ##STR80## wherein D and G represent hydrogen or alkyl having less than 18 carbon atoms and v, z and u are whole numbers ranging from 0 to 11, with two of v, z and u simultaneously being capable of being 0, such that the sum (v+z+u) is greater than or equal to 1 and lower than 18 and such that the sum (v+z+u) is greater than 1 when the sum (x+y+t) is equal to 0,(3) ##STR81## and (4) --(CH2)n --O--(CH2)n -- wherein n is 2 or 3; and

    X⊖

    is an anion derived from an organic or mineral acid, said polymer having a molecular weight ranging between 5,000 and 50,000 and being present in an amount between 0.25 and 10 percent by weight of said composition,wherein said composition is applied in an amount sufficient to provide a protective effect for the hair or to improve the quality of the hair.
