Definitions

• the hair is first treated with the aqueous solution of a reducing compound, in particular a mercapto compound, especially with thioglycolate in an alkaline medium, or else with sulfite, preferably in a weakly acidic to neutral medium.
• a reducing compound in particular a mercapto compound
• thioglycolate in an alkaline medium
• sulfite preferably in a weakly acidic to neutral medium.
• the practical implementation of permanent shaping of human hair is generally carried out in two ways.
• the washed and towel-dried hair is first divided into several sections, these sections are then pre-moistened with a part of a liquid permanent shaping agent and then wound on rollers. After the winding process has ended, the winders are moistened with the rest of the liquid permanent shaping agent.
• the towel-dried hair is also first divided into several sections and then wound onto curlers without pre-moistening with a permanent shaping agent. After the winding process has been completed, the winders are thoroughly moistened with the entire amount of permanent shaping agent required for this.
• the curlers used for permanent waving have a diameter of approximately 5 to 13 millimeters, while curlers with a diameter of more than 13 millimeters are required for hair frizzing.
• the time of action of the hair shaping agent on the hair is both in the permanent waving and in the permanent crumbling, depending on the hair texture and the ge generally desired up to about 30 hints of deformation.
• the exposure time can be shortened by supplying heat, for example using a heat radiator or a drying hood.
• the wound hair is rinsed with water and with the aqueous reading of an oxidizing agent, preferably with an approximately 2% hydrogen peroxide solution, with the previous split again
• the action time of the fixing agent is usually about 10 to 15 minutes. Finally, the curlers are removed and the hair is rinsed thoroughly with water.
• parts of the mercapto compound or the sulphite contained as reducing corrugated active substances are oxidized by atmospheric oxygen. If the hair shaping agent is acidic, the corrugated active substance can even decompose with the elimination of malodorous hydrogen sulfide.
• the lack of shielding of the winders ultimately results in a loss of liquid and heat.
• the permanent deformation in the area of the hairline is unsatisfactory.
• you lengthen the exposure time or choose a more deforming agent you will get sufficient deformation in the area of the hairline, but the hair tips will be damaged.
• This negative result is further exacerbated by the fact that the hair tips are more sensitive to chemical influences than the hairline. Added to this is the fact that the hair tips are first wound on the curler and are therefore more curved than the hairline lying above.
• the aim of permanent hair shaping is, however, a uniform shaping from the hair tips to the hairline without damage to the hair tips.
• the winders can be shielded by the use of foam-like permanent formulations.
• a closed, stable foam layer is applied to the winder.
• the disadvantage here is the unavoidable simultaneous wetting of the scalp and the uncontrolled drainage of the deformation fluid released from the disintegrating foam.
• the object of the invention is therefore a method for permanent shaping of hair, in which the disadvantages described above are avoided and a reliable and uniform shaping of the hair is achieved in a simple manner.
• the hair is treated with a liquid hair-reducing ratin-reducing permanent shaping agent before rolling up on rollers and / or after rolling on rollers,
• the permanent shaping agent mixture is rinsed off the hair and the hair is treated with an oxidizing solution, is dissolved in an excellent manner.
• the liquid permanent shaping agent to be used in the process according to the invention and also the consistent permanent shaping agent each contain sulfite or certain merzapto compounds, in particular salts or derivatives of thioglycolic acid such as ammonium thioglycolate, ammonium thiol actate and glycerol monothioglycolate, as the deformation-effective hair keratin-reducing active ingredient.
• sulfite or certain merzapto compounds in particular salts or derivatives of thioglycolic acid such as ammonium thioglycolate, ammonium thiol actate and glycerol monothioglycolate, as the deformation-effective hair keratin-reducing active ingredient.
• the liquid and the consistent permanent shaping agent each contain the same hair keratin-reducing active ingredient.
• Possible liquid permanent shaping agents are all liquid permanent permanent shaping agents which are weakly deformable for the hair and which, with the usual exposure times of about 10 to 30 minutes, are capable of deforming the hair in the region of the hair tips, but whose deforming effectiveness is too low to the hair peak damage during this period.
• Suitable liquid permanent shaping agents are, for example, those with a content of about 4 to 10% by weight of ammonium thio glycolate and a pH of about 7-8. Further suitable liquid permanent shaping agents can be found in the examples below.
• the consistent permanent shaping agent used in the process described here has a viscosity of 50-5000 mPa.s (millipascal seconds) at a temperature of 30 ° C and has a higher deformation effectiveness than the liquid permanent shaping agent previously applied to the hair.
• the deforming effectiveness of a permanent shaping agent does not depend solely on the concentration of the hair keratin reducing agent contained therein and. depends on the alkalinity set, but other substances contained, such as certain nourishing additives, have an influence on the effectiveness of the deformation, it is most certainly determined experimentally by comparison. More effective is the permanent shaping agent that enables the same deformation in a shorter time under the same conditions of use, that is, when using the same winder, at the same temperature and with the same tension when winding, on the same hair.
• the consistent permanent shaping agent can, for example, be more effective than the liquid permanent shaping agent due to the following factors:
• the consistent permanent shaping agent is, moreover, a dispersion, an emulsion or a mixture of an aqueous solution of a known hair keratin-reducing active ingredient and optionally an alkalizing agent with suitable fillers, thickeners and / or emulators as well as additives customary in hair shaping agents, which can be achieved by a suitable choice of type and amount of contained fillers, thickeners and / or emulsifiers to a viscosity of 50 to 5000 m Pa s, preferably 100 to 500 m Pa s, at 30 ° C, is set. In particular, it is in the form of a gel or cream.
• Suitable fillers are, for example, kaolin, montmorillonite and / or calcium carbonate, while wheat flour, tylose, starch, gelatin, cellulose derivatives and carboxyvinyl polymers can serve as thickeners.
• Higher fatty alcohols, fatty acid esters, liquid and solid paraffins, isoporaffins, petroleum jelly and wool wax are examples of compounds which give stable creams in combination with a suitable errulsifier.
• Suitable emulsifiers include fatty alcohol sulfates, fatty acid alkanolamides, alkyl sulfonates, alkyl benzene sulfonates, ethoxylated fatty alcohols and ethoxylated nonyl phenols.
• both the liquid and the consistent permanent shaping agent can be additives customary in cosmetic agents, such as, for example, antioxidants, perfume oils, complexing agents, dyes, and lower aliphatic Contain alcohols such as ethanol and isopropanol, wetting agents, opacifiers, protective and nourishing additives such as urea, lanolin derivatives, cholesterol and pantothenic acid.
• cosmetic agents such as, for example, antioxidants, perfume oils, complexing agents, dyes, and lower aliphatic Contain alcohols such as ethanol and isopropanol, wetting agents, opacifiers, protective and nourishing additives such as urea, lanolin derivatives, cholesterol and pantothenic acid.
• the washed and towel-dried hair is either immediately soaked with the liquid, less deformable permanent shaping agent (pre-moistened) or the hair is first divided into lots, wiked on curlers and only then soaked with the liquid permanent shaping agent. It is also possible to wet (pre-and re-wet) the hair with the liquid permanent shaping agent for more intensive penetration before and after winding.
• the method of moistening the hair wound on curlers with the liquid permanent shaping liquid is preferable. The hairdresser's hands do not come into contact with the permanent shaping agent.
• the consistent, stronger deformation-effective permanent shaping agent is now applied to the hair moistened with the liquid permanent shaping agent and wound on curlers in a uniform, closed layer.
• the consistent permanent shaping agent can be pressed directly from a tube or a compressed gas pack or applied to the hair with an aid such as a brush or spatula.
• the wound hair is rinsed thoroughly with water and then by treating the hair fixed with the aqueous solution of an oxidizing agent in the new form.
• the new method according to the invention for the permanent shaping of hair has numerous compared to known methods Advantage e on.
• the hairdresser's hands when using the pre-moistening (before changing) method, the hairdresser's hands only come into contact with a weakly deforming and therefore less aggressive liquid permanent shaping agent. Furthermore, only the liquid, weakly deforming permanent shaping agent acts on the sensitive hair tips, since the consistent, more deforming permanent shaping agent applied later cannot penetrate into the innermost layers of the wound hair. Finally, the coils are shielded by the consistent permanent deformation agent. This shield largely prevents the entry of atmospheric oxygen and at the same time considerably reduces the escape of volatile alkalizing agents such as ammonia and the drying out of the top layer of the wound hair.
• Two strands of hair of the same weight and the same hair are wound on curlers of the same diameter and moistened with the same amount of a permanent shaping liquid.
• a consistent permanent shaping agent according to Example 3 according to the invention is then applied to one of the winders.
• the method according to the invention is equally well suited for permanent waving and hair removal.
• only the diameter of the curlers to be used from 5 to 13 millimeters in the case of permanent waving and over 13 millimeters in the case of hair curling, must be adapted to the corresponding application.
