Method for permanent waving and means for practicing this method

A protective device for perming a hair with a permanent product only adjacent to the root of said hair and shielding from the permanent product effect the portion of the hair which is not adjacent to said root, comprising the combination of:

• a watertight, flexible material sheet,
• two curved, rigidified parts fixed to and extending along two opposite edges of said sheet,
• and arresting means fixed to and extending along the free edge of one of said parts, said arresting means being adapted to prevent the permanent product from running along the hair under the sheet due to capillary effect.

A method for carrying out a permanent wave on a hair only in the vicinity of the root of the latter by subjecting the hair to the action of a permanent wave product which comprises arranging a protective sheet along the out-stretched hair in line with the portion of the latter to be shielded from the action of the permanent wave product, winding the hair from the tip thereof with a hair curler while said sheet is situated on the same side of the hair as said curler so that on completion of said winding only the portion of the hair to be treated remains accessible to the action of said permanent wave product and treating said accessible hair with said permanent wave product, said protective sheet comprising the combination of:

• a watertight, flexible material sheet,
• a curved, rigidified part fixed to and extending along one edge of said sheet,
• and arresting means fixed to and extending along the edge of the sheet opposite to the said edge, said arresting means being adapted to prevent permanent product from running along the hair under the sheet due to capillary effect.
