Definitions

  • the present invention relates to the application of a hairstyling composition comprising a fixing agent for shaping the hair.
  • the most widespread devices for shaping and/or fixing a hairstyle are aerosol systems that deliver droplets of a haircare product propelled by a gas, generally a liquefied gas, based on an alcoholic or aqueous solution and polymer resins, forming fine joins between the individual hairs upon drying.
  • a gas generally a liquefied gas, based on an alcoholic or aqueous solution and polymer resins, forming fine joins between the individual hairs upon drying.
  • some fixing compounds are in a usually semi-solid, viscous or powdery form, and it is difficult to employ them by diffusion in the form of a spray, in particular to ensure an even distribution on all the hair to be treated. In order to make them compatible with such a diffusion process, they should be diluted highly in solvents, causing them to lose their effectiveness in terms of fixing.
  • the Applicant Company has developed an applicator comprising a plurality of protruding spikes that delimit, at their free ends, cavities for retaining the composition to be applied.
  • an applicator comprising a plurality of protruding spikes that delimit, at their free ends, cavities for retaining the composition to be applied.
  • the composition is retained inside said cavities by capillary action before being deposited on the hair in the form of droplets.
  • stiffening effects are often brought about on the hair, these being due to the formation of very wide joins, which are much larger than the size of the cavities of the spikes.
  • Another solution consists in increasing the size of the cavities of the spikes of the applicator so as to increase, after deposition and drying of the composition, the fixing power of each individual join and thus that of the final fixing.
  • the size of the joins is large, subsequently leading to disentangling difficulties.
  • the subject of the invention is a method for applying a hairstyling composition comprising at least one fixing agent to the hair with the aid of an applicator comprising a plurality of spikes provided with end parts having a flat shape or a cross section that decreases in the direction of their free ends.
  • the method comprises:
  • the flat shape of the end parts, or the section of these end parts that decreases in the direction of their free ends, promotes the retention of the composition on the applicator and then the transfer thereof to the hair in the form of films, and not in the form of droplets as is the case with the cavities of the abovementioned prior-art applicator.
  • the hairstyling composition can also be liquid or have a liquid phase. The composition is then retained on the spikes of the applicator by capillary action.
  • spikes is understood to mean separable protruding elements on the applicator.
  • the spikes can have a cylindrical, conical, parallelepipedal, triangular, etc. shape.
  • the expression“tapping the spikes of the applicator on the hair” is understood to mean the action of applying the spikes several times to the area of the hair to be treated using a back and forth movement.
  • This type of application without spraying does not destroy the hairstyle and, without the applicator being rubbed along the hair, makes it possible to achieve a very high quality fixing effect, which is equivalent for example to the result obtained with a conventional aerosol lacquer, without the drawbacks thereof. In particular, it allows good distribution of the hairstyling composition.
  • the composition can be applied precisely, without running.
  • the invention gives the hairstyle a natural and long-lasting hold.
  • the characteristics of the films deposited on the hair can be controlled by choosing the dimensions of the end parts of the applicator. It is also possible to adapt the characteristics of the applicator depending on the type of application desired, in particular weaker or stronger fixing, hair design or styling, for example by choosing a higher or lower spike density and/or by choosing the material of the applicator.
  • the surface tensions observed at the end parts of the spikes depend on the material chosen. If the end parts are perfectly hydrophobic, it is difficult or even impossible to create films of water or aqueous composition that have satisfactory size. If the end parts are very hydrophilic, the films may not be transferred easily.
  • the step of transferring the hairstyling composition to the hair is realized by directly tapping the end parts of the spikes of said applicator on the hair.
  • the applicator advantageously comprises a base delimiting a frontal surface from which the spikes extend.
  • the density of spikes on the frontal surface may be between 1 and 20 per cm 2 , and preferably between 3 and 12 per cm 2 .
  • Said frontal surface of the base of the applicator may measure between 10 and 1000 cm 2 , and preferably between 50 and 400 cm 2 .
  • the total number of spikes may vary from 20 to 20 000, better still from 50 to 10 000, and preferably from 100 to 2000.
  • the spikes extend in the same direction and are the same height.
  • the combing spikes may be identical to one another.
  • the spikes may for example have a constant section over their entire height when the end parts are flat.
  • the spikes have, for example, a section that is circular or polygonal, such as rectangular, square, etc.
  • the transverse dimension of the spikes may be between 0.3 mm and 3 mm, and preferably between 0.8 mm and 2 mm.
  • the end parts of the spikes are flat or have a section that decreases in the direction of their free ends.
  • they can be realized for example in the form of points or portions of spheres, in particular of hemispheres.
  • the height of the end parts can be less than or equal to four times the transverse dimension of the spikes away from said end parts.
  • the method according to the invention may be implemented on dry hair or wet hair.
  • the hair is dry.
  • the composition is transferred to the hair by tapping the spikes of the applicator. Therefore, the transfer can be executed by capillary action.
  • this mechanical action may be brought about for example by a vibration generator mounted on the applicator, for example a piezoelectric element or a flyweight driven in rotation, by a pressure source, or be a thermal or electric phenomenon.
  • the applicator can be withdrawn and the films of composition deposited on the hair dried, for example with the aid of a hair dryer or heating hood, or left to dry naturally.
  • the applicator is subjected to an air jet.
  • the use of an air jet may make it easier to transfer the composition onto the hair.
  • the air jet may be an air jet that is hot, cold or at ambient temperature.
  • the air jet may be produced by a source of compressed air or the blower of a hair dryer or hood.
  • the method comprises a prior step of loading the applicator with the hairstyling composition to be applied.
  • the composition can be picked up directly by the spikes of the applicator from a container containing the composition, or by the spikes being brought into contact with a support impregnated or loaded with composition.
  • the spikes of the applicator may be be pressed onto a sponge impregnated with composition, in order to be loaded with composition.
  • the spikes of the applicator may also be brought into contact with a roller loaded with composition.
  • the applicator may be dipped in the composition contained in a container in order to pick the composition up directly with the spikes.
  • the applicator can be cleaned after use and the composition remaining on the applicator after use can be removed easily, the applicator being cleaned for example with water or with the aid of any suitable solvent, by using an absorbent cloth, by aspiration or by gas jet, etc.
  • the applicator is reloaded for example with a composition identical to the composition used previously, or it can be loaded with a different composition.
  • the loading of composition onto the applicator may involve the removal of excess composition from the applicator so that the composition is not present anywhere other than on the end parts of the spikes.
  • compositions that can be used are in the form of liquids or gel creams, pastes, which may or may not comprise a pulverulent phase, or powder.
  • the composition When the composition is liquid, it may be in the form of a lotion or emulsion
  • the composition is in the form of a liquid, a lotion or a fluid emulsion or a gel that is not very thick.
  • the viscosity of the composition varies preferably from 1 to 200 cps at 25°C and at a shear rate of ls 1 .
  • the viscosity measurements to which reference is made are taken using a rheometer with cone-plate geometry.
  • composition known to a person skilled in the art for styling and fixing the hair may be chosen, in particular those that are introduced into aerosol devices in the presence of a propellant gas so as to be used in lacquer form.
  • the composition comprises at least one fixing agent, if necessary in a cosmetically acceptable medium, the latter preferably being water-, alcohol- or aqueous alcohol-based.
  • the cosmetic composition may in particular comprise one or more organic solvents, preferably in an amount by mass of between 0.05 and 95%, very preferably between 1 and 70% by weight, relative to the total weight of the composition.
