Using rollers having roller members which are adjacent on both sides to a center flexible longitudinal section capable of remaining in a respective bent position and have at each end an outer longitudinal section, previously perm or water-waved (pretreated) hair sections of a strand of hair are spirally rolled up, starting with the tips of the hair, first onto one outer longitudinal section, continuing then also onto the center longitudinal section, and finally the previously untreated hair section (hairline) is rolled substantially onto the other outer longitudinal section. The one outer longitudinal section is then bent approximately normally relative to the other outer longitudinal section such that the one outer longitudinal section and a portion of the center longitudinal section with the rolled-up previously treated hair section project substantially vertically upwardly from the head. Intensive-action perm or water-wave liquid is then applied only to the previously untreated hair section (hairline) rolled up substantially onto the other outer longitudinal section. The roller member of a roller (1) particularly suited for carrying out the process has a first longitudinal section (2) made of a substantially rigid material, which a fixing element (9, 10) is arranged on or engages. The first longitudinal section (2) is connected at one end to a second flexible longitudinal section (3) made of a flexible member (5) of a viscoelastic plastic, which flexible member (5) is arranged around a wire core (4).
In a process for applying a perm or water wave to previously permed or water-waved hair using rollers, the roller members of which, being adjacent on both sides to a center flexible longitudinal section capable of remaining in a respective bent position, each have an outer longitudinal section, including the steps of rolling a hair strand on ahead onto the roller member starting with the tips of the hairs, then securing the roller member relative to the head and thereafter applying a perm or waterwave liquid onto the rolled-up hair, the improvement comprising the steps of spirally rolling previously permed or water-waved sections of the strand of hair, starting with the tips of the hair, first onto a first of said outer longitudinal sections, and then progressively also onto the center longitudinal section, and finally spirally rolling the untreated section of hair substantially onto a second of said outer longitudinal sections, then bending the roller member until said first outer longitudinal section extends approximately at a right angle relative to said second outer longitudinal section such that said first outer longitudinal section and a portion of the center longitudinal section with the rolled-up previously treated hair sections project substantially perpendicularly outwardly from the head, and then applying intensive-action perm or water-wave liquid to the previously untreated hair section which is rolled up substantially onto said second outer longitudinal section.
In a roller for perms or water waves, comprising a roller member having an outer surface onto which strands of hair on a head can be rolled, and a fixing element with which the roller member with the rolled-up strand of hair can be securely fixed against rotation relative to the head, the improvement comprising wherein the roller member has a first longitudinal section made of a substantially rigid material, with which first longitudinal section the fixing element cooperates, said rigid first longitudinal section having an outer surface onto which a portion of said strands of hair are rolled, and wherein said rigid first longitudinal section is connected at one end to a second longitudinal section which is a flexible member of a visoelastic plastic, the flexible member being arranged around a center wire core so that, after being bent, said second longitudinal section remains in the bent position.
A process for applying a perm or water wave to a strand of hair on a head using a roller member which includes a flexible first section capable of remaining in a respective bent position and includes a rigid second section coupled to one end of said first section, comprising the steps of rolling onto said first section of said roller member a portion of the strand of hair spaced from the head and rolling onto said second section a second portion of the strand of hair adjacent said head, and thereafter applying a perm or water wave liquid to said second portion of said strand which is on said rigid second section.
