AI Technical Summary

Benefits of technology

[0009] The inventors have surprisingly found that the tension on the hair wound on the curlers can be automatically increased during the hair waving process and all other disadvantages discussed above are avoided, when a method according to the invention is used.

Problems solved by technology

In order to bring all of the curlers (about 30 to about 50) under tension much time and effort is needed by the hairdresser and it is impossible to apply the same quantity of tension on each of the curlers.

example 1

[0043] A non-woven fleece Sawaloom 06615SO16 needle punched non-woven, including about 50% of the super-absorbent fiber PP / 30% CV / 20% SAP 180 g / m2, having a thickness of about 3 mm, is cut into a sheet with the dimensions length about 120 mm and width about 70 mm. This curling sheet is folded along the longitudinal axis around the hair tips in the way as with an end wrap.

[0044] The hair is wound up by hand or by the aid of a clip without the use of curlers, just using the curling sheet as the curler. The curl is fixed with a clip, e.g., Wella Creative Shaper®. A conventional permanent waving composition of the formula below is evenly distributed onto the rolled hair. The curling sheet, which serves as a curler, swells by absorption of the aqueous liquid and produces tension on the hair wound on it.

example 2

[0047] Natural hair of about 25 cm length on the left side of the head is wound with commercial paper end-wraps on curlers of about 30 mm diameter (Wella Creative Shaper No.23). On the right side the hair is wound on curling sheets of example 1. Then the hair on both sides of the head is treated as disclosed in example 1.

[0048] The hair is treated with the curling sheets according to the invention (right side) shows a more even curl from the tip to the roots compared to the hair on the left side, treated conventionally. No overcurling at the tips is noticed. The hair on the right side moreover shows a more natural and well-groomed look.

This curling sheet is folded along the longitudinal axis around the hair tips in the way as with an end wrap.

[0050] Natural hair of about 20 cm length is wound up by the aid of a clip, using the curling sheet as the curler. The curl is fixed with a pin. A non-aerosol hair spray composition of the formula below is evenly sprayed onto the rolled 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.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a method of hair shaping for the winding of the hair on curlers. A curler in form of a sheet is used, which serves also as an end-wrap and the sheet is provided at least partially with at least one super-absorbent polymer in non-swollen form. BACKGROUND OF THE INVENTION [0002] For producing permanent hair shaping on human hair, winding bodies are required besides the use of a reducing agent and oxidizing agent. The hair is rolled up along its longitudinal axis from the ends of the hair to the roots close to the scalp. The curlers used conventionally in the hairdresser salon have some disadvantages. They display a rigid shape and because of this, when the hair relaxes by the effect of the reducing agent, the tension on the hair is either reduced or completely lost. On the other hand it is well known that the duration and elasticity of the curl can be improved by keeping the hair under tension during the reshaping process....
