Definitions

• the invention relates to a method for the chemical and / or thermal treatment of hair on only part of its length and to winders with a protective cover for carrying out this method.
• the human hair is put under a lot of stress.
• the hair is treated chemically and / or thermally several times in the same or different ways, there is a risk of hair damage, the hair e.g. become brittle and break off easily.
• the human head hair grows on average 1 to 2 cm per month, the growth starting from the hair root. So that the regrown part of the hair shaft does not clearly differ from e.g. the colored, bleached or artificially curled part of the hair shafts, the chemical and / or thermal treatment of the hair must be repeated periodically.
• the entire length of the hair is treated, even if some of the hair shafts are already artificially waved.
• part of the hair shafts is often waved or curled several times at intervals.
• the hair tips can be damaged in such a way that they have to be broken off or cut off.
• the risk of hair damage can also occur if the hair is bleached or dyed several times.
• the object of the present invention is therefore to develop a method for the chemical and / or thermal treatment of hair which does not have the disadvantages mentioned above.
• Another object on which the present invention is based is to develop a means which enables this method to be carried out.
• the present invention therefore relates to a method for the chemical and / or thermal treatment of hair over only part of its length.
• the method according to the invention is characterized in that the part of the hair shaft not to be treated is wound on a winder and covered before the subsequent chemical and / or thermal treatment, in such a way that only the part of the hair shaft to be treated is chemical and / or thermal Treatment remains accessible.
• the part of the hair shafts which is not to be treated is preferably covered by means of a protective sheath which has a slot-shaped opening for the strand of hair running in its longitudinal direction.
• the present method is particularly suitable for permanent wave treatment, which is an example of a chemical and / or thermal treatment.
• the invention is not so limited.
• the method according to the invention and its preferred embodiments are also suitable for other chemical and / or thermal treatments, for example for dyeing or bleaching the hair.
• permanent wave treatment means any treatment for laying a permanent wave, regardless of how much the hair is curled. Special forms such as “mini-vague” are also considered permanent.
• a permanent wave treatment according to the present invention is preferably carried out in such a way that the part of the hair shafts which is not to be treated is wound on a winder and the winder with the hair wound thereon is enclosed with a protective sheath, so that only the part of the hair shafts to be treated is removed from the Protective case protrudes.
• the part of the hair shaft to be treated can then be wound up on the protective cover and subjected to a permanent wave treatment.
• the method according to the invention has the advantage that the re-grown part of the hair shafts can be selectively subjected to the chemical and / or thermal treatment, for example the permanent wave treatment.
• the part of the hair shafts already treated and in particular the hair tips are no longer treated, which is why the risk of hair damage is reduced to a minimum.

However, the two parts can also be connected to one another via an axis. In the latter embodiment, the protective cover is generally easier to handle and generally offers better protection against the agents used for the thermal and / or chemical treatment of the hair, such as e.g. Perm water.
