Abstract
A method treating hair with a liquid treatment substance is disclosed in which lengths of hair which are not to receive treatment are protected by means of a tubular protection device which is impervious to the liquid treatment substance. The tubular protection device comprises an open ended tube of thin rubber and one end of the tube is rolled upon itself to form an annular rolled portion with an end portion protruding therefrom. In use, the end of a length of hair to be protected is inserted into the end portion and the-rolled portion is unrolled to an extent sufficient to enclose all the length of hair to be protected. The protected hair and unprotected hair is rolled onto a curler and the liquid treatment substance is applied to the rolled hair. The protection device serves to prevent the liquid treatment substance coming into contact with the length of hair enclosed within the tube.
