Method for shaping hair

Abstract

A method for shaping hair comprising the steps of: (i) folding a curling sheet consisting of or comprising a super-absorbent material around the tips of the hair strand like an end-wrap; (ii) winding the hair around the folded sheet, thereby using said sheet as a curler; (iii) fixing the curlers with a clip, a pin, or another tool appropriate for fixing the hair on a curler; (iv) applying a aqueous hair shaping composition onto the hair on the curler; (v) leaving the shaping composition to act on the hair for about 1 to about 30 minutes, whereby said sheet is swelling and produces tension on the hair wound on it; and (vi) removing the said sheet.
