Description

Die vorliegende Erfindung betrifft ein Verfahren zur Haarverlängerung und/oder Haarverdichtung.The present invention relates to a method for hair extension and / or hair thickening.

Die Veränderung von Form oder Farbe des Kopfhaares zur Veränderung des Erscheinungsbildes ist allgemein bekannt und weit verbreitet. Kurzzeitiges Styling durch Haargele oder Haarsprays und länger anhaltende Stylings wie Dauerwellen sowie die Färbung oder Blondierung sind gesicherter Stand technischen Wissens und können zum großen Teil auch in Heimanwendung durchgeführt werden.The change of shape or color of the head hair to change the appearance is well known and widely used. Short-term styling through hair gels or hair sprays and longer-lasting styling such as perms as well as the coloring or bleaching are secured state of technical knowledge and can be carried out to a large extent in home use.

Ein weiteres Feld der Veränderung des Erscheinungsbildes hat sich in den letzten Jahren herausgebildet: Die Haarverlängerung. Hierbei handelt es sich um verschiedene Methoden, das Eigenhaar am Kopf durch fremde Echt- oder Kunsthaarsträhnen länger erscheinen zu lassen.Another field of change in appearance has emerged in recent years: the hair extension. These are different methods to make the hair on the head appear longer by foreign real or artificial hair strands.

Das fremde Haar wird dabei strähnenweise mit den eigenen Haaren fest verbunden. Dies kann durch Wärme, Ultraschall oder mechanisch erfolgen. Eine weitere Möglichkeit ist die Einarbeitung von Tressen, bei der reihenweise gearbeitet wird. Die Befestigung findet vor allem am Hinterkopf statt, damit genügend Eigenhaar vom Oberkopf über die Verbindungsstellen fällt.The foreign hair is thereby strands firmly connected with the own hair. This can be done by heat, ultrasound or mechanically. Another possibility is the incorporation of tresses, is worked in rows. The attachment takes place especially at the back of the head, so that sufficient own hair falls from the top of the head over the joints.

Hierbei existieren verschiedene Methoden:

  • Bei der Bellargo-Methode werden Strähnen aus europäischem unbehandeltem Schnitthaar mit Hilfe von winzigen Hülsen durch Wärmeeinwirkung am Eigenhaar befestigt.
  • Bei der Klebe- oder Bonding-Methode werden vorbehandelte Strähnen aus europäischem oder indischem Naturhaar an das Eigenhaar angeklebt. (unter Wärmeeinwirkung)
  • Bei der Air-Pressure-Methode werden bis zu zehn Strähnen aus Echthaar gleichzeitig befestigt.
  • Bei der Metallhülsen-Methode wird das Fremdhaar - meist indisches Naturhaar - mit einer speziellen Zange zusammengedrückt.
  • Bei der Kunsthaar-Methode werden Kunstfasern mittels eines Thermoklebers in der Nähe der Kopfhaut befestigt Kunsthaare werden auch mit Metallspangen eingeklemmt.
There are different methods:
  • In the Bellargo method strands of European untreated cut hair are attached by means of tiny sleeves by heat on the own hair.
  • In the bonding or bonding method pretreated strands of European or Indian natural hair are adhered to the own hair. (under heat effect)
  • In the air pressure method, up to ten strands of human hair are attached at the same time.
  • In the metal sleeve method, the foreign hair - usually Indian natural hair - is compressed with special pliers.
  • In the synthetic hair method, synthetic fibers are attached by means of a thermo-adhesive near the scalp. Artificial hair is also pinched with metal clips.

Beim Anmodulieren mit Wärme wird Thermoklebstoff, Wachs, Keratin oder eine Silikonbasis bei ca. 90 - 130 °C benutzt, bei Ultraschall werden die Keratinplättchen (so genannte Bondings) auf molekularer Ebene kurzzeitig erwärmt, mechanische Methoden mit Plastik- oder Metallhülsen arbeiten ohne Wärme.When modulating with heat, thermoadhesive, wax, keratin or a silicone base is used at approx. 90 - 130 ° C. On ultrasound, the keratin platelets (so-called bonding) are briefly heated at the molecular level; mechanical methods using plastic or metal sleeves work without heat.

Eine Haarverlängerung hält bis zu 6 Monate, die Kosten variieren stark je nach Qualität der eingesetzten Haare und der angewendeten Einarbeitungsmethode.A hair extension lasts up to 6 months, the costs vary greatly depending on the quality of the hair used and the method of incorporation used.

Es sind andere Verfahren zur Herstellung einer Verbindung zwischen den Haarsträhnen und dem Eigenhaar bekannt, die externe Elemente, wie Spangen, Kämme, Klemmen usw. verwenden: Diese Elemente können dazu verwendet werden, Haarsträhnen mit größeren Abmessungen an das Haar des Anwenders zu befestigen, sie haben aber den großen Nachteil, dass ihre Verbindung deutlich sichtbar und durch den Anwender fühlbar ist, der dies als störend empfinden kann.Other methods of making a bond between the hair strands and the self-hair using external elements such as clips, combs, clips, etc. are known: these elements can be used to attach strands of hair of larger dimensions to the hair of the user but have the big disadvantage that their connection is clearly visible and felt by the user, who may find this disturbing.

Beispiele für Haarverlängerungsverfahren sind aus den Druckschriften JP 03152205 (Aderans Co. Ltd.) und in der ZA 93/5214 A oder in der DE 196 26 107 C1 beschrieben. Verfahren, bei denen ein Klebstoff auf die entstehende Verbindung aufgebracht wird, sind beispielsweise in der US 4,934,387 (Megna) beschrieben. Ein Verfahren zur Befestigung einer selbsthaftenden Haarsträhne ist in der US-A-6,135,122 offenbart. Die DE 202 03 301 U1 offenbart schließlich eine Vorrichtung und ein Verfahren, bei dem mehrere Haarsträhnen mit Klebestellen an einer gemeinsamen Trägerfolie vorliegen und so gleichzeitig appliziert werden können.Examples of hair extension methods are from the documents JP 03152205 (Aderans Co. Ltd.) and in the ZA 93/5214 A or in the DE 196 26 107 C1 described. Methods in which an adhesive is applied to the resulting compound, for example, in US 4,934,387 (Megna). A method of attaching a self-adhesive strand of hair is in the US-A-6,135,122 disclosed. The DE 202 03 301 U1 finally discloses a device and a method in which several strands of hair are present with splices on a common carrier film and can be applied simultaneously.

Der vorliegenden Erfindung lag die Aufgabe zugrunde, das Gebiet der anklebbaren Haarsträhnen weiterzuentwickeln und insbesondere die Applikationszeiten zu verkürzen und das spätere Entfernen der Strähnen zu vereinfachen.It was an object of the present invention to further develop the field of adhesive hair strands and in particular to shorten the application times and to simplify the later removal of the strands.

Es wurde nun gefunden, daß sich bestimmte Vorgehensweisen besonders zur Lösung dieser Aufgabe eignen und die Applikationsmöglichkeiten deutlich erweitern, so daß nicht mehr zwingend mit Wärme gearbeitet werden muß.It has now been found that certain approaches are particularly suitable for solving this problem and significantly expand the application possibilities, so that it is no longer necessary to work with heat.

Gegenstand der vorliegenden Erfindung ist in einer ersten Ausführungsform ein Verfahren zur Haarverlängerung und/oder Haarverdichtung, umfassend die folgenden Schritte:

  • Bereitstellung mindestens einer Haarsträhne, die mit einem Befestigungslement versehen ist;
  • Aufquellen des Befestigungselementes durch Aufbringen mindestens eines Lösungsmittels auf das Befestigungselement,
  • Anbringen an (jeweils) einer Haarsträhne des Eigenhaares und
  • Verdampfenlassen des Lösungsmittels.
The present invention in a first embodiment is a method for hair extension and / or hair thickening, comprising the following steps:
  • Providing at least one strand of hair provided with a fastening element;
  • Swelling of the fastener by applying at least one solvent to the fastener,
  • Attach to (in each case) a strand of hair of the own hair and
  • Allowing the solvent to evaporate.

Im ersten Schritt des erfindungsgemäßen Verfahrens wird eine mindestens Haarsträhne bereitgestellt, die mit einem Befestigungselement versehen ist. Eine solche Haarsträhne besteht aus einem Haarteil, an dem ein Befestigungselement angebracht ist. Das Haarteil besteht aus einer Mehrzahl von natürlichen und/oder künstlichen Fasern ("Haarsträhne"). Natürliche ("echte") Haare stammen oft aus Indien oder China, da hier Frisuren oft traditionell lang sind. In Indien werden die Zöpfe teilweise aus religiösen Motiven abgeschnitten. Heute stammen die meisten Menschenhaare aus Indien. Auch Tierhaare können erfindungsgemäß eingesetzt werden, bewährt hat sich hierbei beispielsweise Büffelbauchhaar. Die Haare werden gewaschen, nach Länge sortiert, gekraust und gefärbt. Teilweise wird auch die äußere Schuppenschicht entfernt, um ein Filzen zu verhindern.In the first step of the method according to the invention, an at least hair strand is provided, which is provided with a fastening element. Such a strand of hair consists of a hairpiece to which a fastener is attached. The hairpiece consists of a plurality of natural and / or artificial fibers ("strand of hair"). Natural ("real") hair often comes from India or China, as hairstyles are often traditionally long. In India, the braids are partially cut off for religious reasons. Today, most human hair comes from India. Animal hairs can also be used according to the invention; buffalo belly hair, for example, has proved to be useful in this case. The hair is washed, sorted by length, curled and dyed. Partially, the outer cuticle layer is removed to prevent felts.

Erfindungsgemäß einsetzbare Haarsträhnen können auch aus Kunsthaar hergestellt werden. Ein weit verbreitetes Material sind Kunstfasern aus Poly-(acrylnitril-co-vinylchlorid) von der Firma Kanekalon. Auch Strähnen, in denen sowohl natürliche Haare als auch Kunstfasern nebeneinander vorliegen, sind erfindungsgemäß geeignet.Hair strands which can be used according to the invention can also be produced from synthetic hair. A widely used material is synthetic fibers of poly (acrylonitrile-co-vinyl chloride) from Kanekalon. Strands in which both natural hair and synthetic fibers are present next to each other, are suitable according to the invention.

Am Haarteil befindet sich ein Befestigungselement, das vorzugsweise an einem Ende der Haarsträhne angebracht wird. Ein Anbringen des Befestigungselementes an anderen Stellen, beispielsweise in der Mitte einer Haarsträhne ist ebenfalls möglich - hierdurch wird aber ja nach Länge der Haarsträhne ein unnatürlicher Strähnenverlauf erzeugt. Vorzugsweise liegt das Befestigungselement daher an einem Ende (nachfolgend als "oberes Ende" bezeichnet) der Haarstsrähne vor.On the hairpiece is a fastener, which is preferably attached to one end of the hair strand. An attachment of the fastener in other places, for example in the middle of a strand of hair is also possible - but this is indeed produced by the length of the strand of hair an unnatural strands course. Preferably, the fastener is therefore at one end (hereinafter referred to as "upper end") of the Haarstsrähne before.

Das Befestigungselement ist vorzugsweise klein und dünn dimensioniert, damit die spätere Befestigungsstelle am Kopf nicht auffällt. Bevorzugte Befestigungselemente weisen räumliche Ausdehnungen im Millimeter-Bereich auf, beispielsweise Höhen von 1 bis 4 mm und Längen bzw. Breiten von 5 bis 80 mm, vorzugsweise von 10 bis 70 mm, besonders bevorzugt von 20 bis 60 mm und insbesondere 30 bis 50 mm.The fastener is preferably small and thin dimensioned so that the subsequent attachment point on the head is not noticeable. Preferred fasteners have spatial dimensions in the millimeter range, for example, heights of 1 to 4 mm and lengths or widths of 5 to 80 mm, preferably from 10 to 70 mm, more preferably from 20 to 60 mm and in particular 30 to 50 mm.

Um im erfindungsgemäßen Verfahren einsetzbar zu sein, muß das Befestigungselement in der Lage sein, durch Lösungsmittel gequollen werden zu können. Hier haben sich insbesondere Polymere bewährt, die beispielsweise aus den Gruppen der natürlichen oder der synthetischen Polymere stammen können. Im Hinblick auf die Lagerfähigkeit der zu applizierenden Strähnen, auf die Widerstandsfähigkeit gegen atmosphärische Einflüsse bei der späteren Anwendung und auf die Applikationszeit haben sich synthetische Polymere besonders bewährt.In order to be usable in the method according to the invention, the fastener must be able to be swollen by solvents. Here in particular polymers have proven, which can originate for example from the groups of the natural or the synthetic polymers. In view of the shelf life of the strands to be applied, the resistance to atmospheric influences in the subsequent application and on the application time, synthetic polymers have proven particularly useful.

Erfindungsgemäß bevorzugte Verfahren sind dadurch gekennzeichnet, daß das Befestigungselement - bezogen auf das Gewicht des Befestigungselementes - mindestens 10 Gew.-%, vorzugsweise mindestens 25 Gew.-%, weiter bevorzugt mindestens 50 Gew.-%, noch weiter bevorzugt mindestens 75 Gew.-% und insbesondere mindestens 90 Gew.-% synthetische(s) Polymere(e) enthält.According to preferred methods are characterized in that the fastener - based on the weight of the fastener - at least 10 wt .-%, preferably at least 25 wt .-%, more preferably at least 50 wt .-%, still more preferably at least 75% by weight and in particular at least 90% by weight of synthetic polymer (s).

Unter dem begriff "synthetische Polymere" werden im Rahmen der vorliegenden Anmeldung Kunststoffe verstanden, die nach allen für die Synthese von Polymeren üblichen Polyreaktionen-Polyadditionen, Polykondensationen und Polymerisationen- und Polymer-analogen Reaktionen herstellbar sind.In the context of the present application, the term "synthetic polymers" refers to plastics which can be prepared by all polyreaction polyadditions, polycondensations and polymerizations and polymer-analogous reactions customary for the synthesis of polymers.

In besonders bevorzugten Ausführungsformen der vorliegenden Erfindung umfaßt das Befestigungselement erfindungsgemäß mindestens ein Polyurehan (PU-)-Polymer.In particularly preferred embodiments of the present invention, the fastening element according to the invention comprises at least one polyurehane (PU) polymer.

Polyurethan ist die Sammelbezeichnung für Polymere, in deren Makromolekülen die Wiederholungseinheiten durch Urethan-Gruppierungen -NH-CO-O- verknüpft sind. Polyurethane werden im Allgemeinen erhalten durch Polyaddition aus zwei- oder höherwertigen Alkoholen und Isocyanaten gemäß

Figure imgb0001
R1 und R2 können dabei für niedermolekulare oder selbst schon polymere aliphatische oder aromatische Gruppen stehen. Technisch wichtige Polyurethane werden hergestellt aus Polyester- und/oder Polyetherdiolen und z.B. 2,4- bzw. 2,6-Toluoldiisocyanat (TDI, R2 = C6H3-CH3), 4,4'-Methylenbis(phenylisocyanat) (MDI, R2 = C6H4-CH2-C6H4), 4,4'-Methylendicyclohexylisocyanat (HMDI, R2 = C6H10-CH2-C6H10) od. Hexamethylendiisocyanat [HDI, R2 = (CH2)6].Polyurethane is the collective name for polymers in whose macromolecules the repeating units are linked by urethane groups -NH-CO-O-. Polyurethanes are generally obtained by polyaddition from dihydric or higher alcohols and isocyanates according to
Figure imgb0001
 R 1 and R 2 may stand for low molecular weight or even already polymeric aliphatic or aromatic groups. Technically important polyurethanes are prepared from polyester and / or polyether diols and, for example, 2,4- and 2,6-toluene diisocyanate (TDI, R 2 = C 6 H 3 -CH 3 ), 4,4'-methylenebis (phenyl isocyanate) ( MDI, R 2 = C 6 H 4 -CH 2 -C 6 H 4 ), 4,4'-methylenedicyclohexyl isocyanate (HMDI, R 2 = C 6 H 10 -CH 2 -C 6 H 10 ) or hexamethylene diisocyanate [HDI, R 2 = (CH 2 ) 6 ].

Erfindungsgemäß besonders bevorzugte Verfahren sind dadurch gekennzeichnet, daß das Befestigungselement - bezogen auf das Gewicht des Befestigungselementes - mindestens 10 Gew.-%, vorzugsweise mindestens 25 Gew.-%, weiter bevorzugt mindestens 50 Gew.-%, noch weiter bevorzugt mindestens 75 Gew.-% und insbesondere mindestens 90 Gew.-% Polyurethan-Polymer(e) enthält.Particularly preferred according to the invention processes are characterized in that the fastener - based on the weight of the fastener - at least 10 wt .-%, preferably at least 25 wt .-%, more preferably at least 50 wt .-%, even more preferably at least 75 wt. % and in particular at least 90 wt .-% polyurethane polymer (s).

Das Anbringen der zuvor bereitgestellten Haarsträhne an das Eigenhaar erfolgt im erfindungsgemäßen Verfahren dadurch, daß man das Befestigungselement mit einem Lösungsmittel behandelt. Hierdurch quillt das Befestigungselement auf und wird so adhäsiv, daß es an einer Haarsträhne des Eigenhaares befestigt werden kann. Das Lösungsmittel verdampft anschließend, und die Befestigungsstelle verliert ihre Klebrigkeit. Auf diese Weise ist der aus dem Stand der Technik bekannte notwendige Einsatz von hohen Temperaturen nicht notwendig. Das erfindungsgemäße Verdampfenlassen des Lösungsmittels kann durch Wärme unterstützt werden (z.B. durch eine Trockenhaube oder den Einsatz eines Warmlufthaartrockners), dies ist aber erfindungsgemäß nicht erforderlich.The attachment of the previously provided strand of hair to the own hair is carried out in the process according to the invention by treating the fastener with a solvent. As a result, the fastener swells and becomes so adhesive that it can be attached to a strand of hair of the own hair. The solvent then evaporates and the attachment site loses its tackiness. In this way, the known from the prior art necessary use of high temperatures is not necessary. The evaporation of the solvent according to the invention can be assisted by heat (for example by a drying hood or the use of a hot air hair dryer), but this is not necessary according to the invention.

Bevorzugt für den Einsatz im erfindungsgemäßen Verfahren sind Lösungsmittel, die das Befestigungselement schnell und zuverlässig aufquellen und nach der Applikation der Strähne zügig verdampfen. Physiologisch weitgehende Unbedenklichkeit ist ein weiteres Kriterium bei der Auswahl geeigneter Lösungsmittel. Besonders bevorzugte erfindungsgemäße Verfahren sind dadurch gekennzeichnet, daß das Lösungsmittel ausgewählt wird aus aus Aceton (DMK), Isopropanol, Hexan, Methylethylketon (MEK) und Ethylacetat.Preferred for use in the process according to the invention are solvents which swell the fastening element quickly and reliably and rapidly evaporate after application of the strand. Physiologically largely harmlessness is another criterion in the selection of suitable solvents. Particularly preferred processes according to the invention are characterized in that the solvent is selected from acetone (DMK), isopropanol, hexane, methyl ethyl ketone (MEK) and ethyl acetate.

In der einfachsten Variante des erfindungsgemäßen Verfahrens werden einzelne Haarsträhnen mit jeweils einem Befestigungselement bereitgestellt und jede Haarsträhne für sich durch Aufquellen des Befestigungselementes durch Aufbringen mindestens eines Lösungsmittels auf das Befestigungselement und Anbringen an (jeweils) einer Haarsträhne des Eigenhaares und Verdampfenlassen des Lösungsmittels am Eigenhaar befestigt.In the simplest variant of the method according to the invention, individual strands of hair are each provided with a fastening element and each strand of hair secured to the own hair by swelling the fastener by applying at least one solvent to the fastener and attaching to (each) a strand of hair of the own hair and allowing the solvent to evaporate.

Es ist mit dem erfindungsgemäßen Verfahren aber auch möglich, eine Mehrzahl von Strähnen gleichzeitig zu applizieren. Dies läßt sich bequem realisieren, indem mehrere Strähnen mit ihren Befestigungselementen auf ein Trägermaterial (z.B. einem Filmstreifen) aufgebracht werden und die Applikation von Lösungsmittel dann auf mehrere Befestigungselemente erfolgt, die auf dem Träger lokalisiert sind. Auf diese Weise werden in einem Applikationsschritt am Eigenhaar an verschiedenen Stellen Haarsträhnen angebracht.However, it is also possible with the method according to the invention to apply a plurality of strands at the same time. This can be conveniently achieved by applying a plurality of strands with their fasteners to a substrate (e.g., a filmstrip) and then applying solvent to a plurality of fasteners located on the substrate. In this way, hair strands are attached to the own hair at different points in an application step.

Eine solche erfindungsgemäß einsetzbare Vorrichtung von Haarsträhnen besteht aus einer Anzahl von Haarsträhnen, die vorzugsweise fluchtend und im Wesentlichen parallel angeordnet sind, und die aus einer Anzahl von im Wesentlichen vorbestimmten Haaren bestehen, die natürlich oder künstlich sein können und geeignet ausgewählte Farben aufweisen, und zwar einfarbig oder mit Strähnchen. Die Haarsträhnen werden vorzugsweise im Wesentlichen in gleichen Abständen angeordnet. Sie erstrecken sich von ihren jeweiligen Enden mit den Befestigungselementen, die dazu ausgestaltet sind, mit dem Kopfhaar verbunden zu werden, bis hin zu ihren freien Enden.Such a device of hair strands which can be used according to the invention consists of a number of strands of hair, which are preferably arranged in alignment and substantially parallel, and which consist of a number of substantially predetermined hairs, which may be natural or artificial and suitably have selected colors monochrome or with highlights. The strands of hair are preferably arranged at substantially equal intervals. They extend from their respective ends to the fasteners which are adapted to be connected to the hair of the head to their free ends.

Eine solche Vorrichtung umfaßt ebenfalls ein Trägerband, auf der die Befestigungselemente angeordnet sind.Such a device also comprises a carrier tape on which the fastening elements are arranged.

Der Werkstoff, der das Trägerband bildet, ist vorzugsweise dünn und filmartig. Er kann nach der Verdampfung des Lösungsmittels aus dem Eigenhaar entfernt werden, was jedoch unangenehmes "Ziepen" zur Folge haben kann. Bevorzugt sind Trägerbänder, die so dünn und unauffällig sind, daß sie im Haar verbleiben können, ohne das Tragegefühl zu stören oder optisch aufzufallen.The material forming the carrier tape is preferably thin and film-like. It can be removed after the evaporation of the solvent from the own hair, which, however, can cause uncomfortable "Ziepen". Preferred are carrier tapes that are so thin and inconspicuous that they can remain in the hair, without disturbing the wearer or attract attention.

In einer bevorzugten Ausführungsform dieser Verfahrensvariante besteht das Trägerband aus saugfähigem Material. Hierdurch wird die Applikation des Lösungsmittels erleichtert und das Aufquellen der Befestigungselemente begünstigt.In a preferred embodiment of this process variant, the carrier tape consists of absorbent material. As a result, the application of the solvent is facilitated and promotes the swelling of the fasteners.

Bevorzugte erfindungsgemäße Verfahren sind dadurch gekennzeichnet, daß die mit einem Befestigungselement versehene(n) Haarsträhne(n) zusätzlich ein Trägerband aufweist/aufweisen, das aus saugfähigem Material besteht.Preferred methods according to the invention are characterized in that the hair strand (s) provided with a fastening element additionally comprises / has a carrier band which consists of absorbent material.

Das Trägerband kann bei dieser Verfahrensvariante eine definierte Länge aufweisen und nur eine einzelne oder eine vorbestimmte Anzahl von Haarsträhnen tragen, oder es kann eine undefinierte Länge aufweisen, so dass die ausführende Person Abschnitte abschneiden kann, um die gewünschte Anzahl von Haarsträhnen zu erhalten. In allen Fällen kann die ausführende Person eine oder mehrere Haarsträhnen, die mit der aktuellen Anbringung nicht kompatibel sind, entfernen, indem sie einfach einen Teil des Trägerbands abschneidet. Auf jeder Anordnung können die Haarsträhnen die gleiche Länge, Größe und Farbe aufweisen, es ist aber auch möglich, Variationen in der Länge vorzusehen, um stufige Verlängerungen herzustellen, sowie Farbvariationen, um komplexe Strähnen und unterschiedliche Größen erzeugen zu können.The carrier tape may in this process variant have a defined length and wear only a single or a predetermined number of strands of hair, or it may have an undefined length, so that the executing person can cut off sections to obtain the desired number of strands of hair. In all cases, the operator may remove one or more strands of hair that are incompatible with the current application simply by cutting off a portion of the carrier tape. In any arrangement, the strands of hair may be the same length, size and color, but it is also possible to provide variations in length to produce stepped extensions, as well as color variations to create complex strands and different sizes.

Eine bevorzugte Variante des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, daß mehrere Haarsträhnen bereitgestellt werden, die fluchtend und im Wesentlichen parallel mit ihren Befestigungselementen auf einem Trägerband angebracht sind.A preferred variant of the method according to the invention is characterized in that a plurality of hair strands are provided, which are mounted in alignment and substantially parallel with their fastening elements on a carrier tape.

Wie bereits erwähnt, sind auch hier Varianten des erfindungsgemäßen Verfahrens bevorzugt, bei denen das Trägerband aus saugfähigem Material besteht.As already mentioned, variants of the method according to the invention are also preferred here in which the carrier tape consists of absorbent material.

Besonders bevorzugte erfindungsgemäße Verfahren sind dadurch gekennzeichnet, daß das Trägerband aus saugfähigem Papier, vorzugsweise aus Filterpapier, besteht.Particularly preferred methods according to the invention are characterized in that the carrier tape consists of absorbent paper, preferably of filter paper.

Bei einer besonderen Ausführungsform befindet sich das erforderliche Lösungsmittel bereits im Befestigungselement, d.h. das Polymer befindet sich bereits im gequollenen Zustand und kann spontan angewandt werden. Diese Ausführungsform erfordert jedoch eine besondere Umverpackung. Verwendet wird hierbei vorzugsweise eine Verblisterung, die gegenüber dem Lösemittel diffusionsstabil ist. Das Applizieren der Haarsträhnen kann direkt nach der Entnahme aus der Umverpackung, beispielsweise der Verblisterung, erfolgen.In a particular embodiment, the required solvent is already in the fastener, ie the polymer is already in the swollen state and can be applied spontaneously. However, this embodiment requires a special outer packaging. A blistering which is diffusion-stable with respect to the solvent is preferably used. The application of the hair strands can be made directly after removal from the outer packaging, such as the Blistering.

Die Anbringung der erfindungsgemäßen Vorrichtung (Haarsträhne) erfolgt vorzugsweise dicht an der Kopfhaut. Hier sind Verfahren bevorzugt, bei denen das Anbringen an (jeweils) einer Haarsträhne des Eigenhaares im Abstand von 0,5 bis 2 cm, vorzugsweise von 0,75 bis 1,5 cm und insbesondere von 0,9 bis 1,1 cm von der Kopfhaut erfolgt.The attachment of the device according to the invention (strand of hair) is preferably carried out close to the scalp. Here are preferred methods in which attaching to (each) a strand of hair of the own hair at a distance of 0.5 to 2 cm, preferably from 0.75 to 1.5 cm and in particular from 0.9 to 1.1 cm from the Scalp takes place.

Das Anmodulieren der erfindungsgemäßen Vorrichtungen an Eigenhaarsträhnen ist mit dem erfindungsgemäßen Verfahren in sehr kurzer Zeit möglich. In bevorzugten erfindungsgemäßen Verfahren erfolgen Erkaltenlassen bzw. Verdampfenlassen des Lösungsmittels über einen Zeitraum von 2 bis 60 Minuten, vorzugsweise von 10 bis 45 Minuten und insbesondere von 20 bis 30 Minuten.The modulating of the devices according to the invention on own hair strands is possible with the method according to the invention in a very short time. In preferred processes according to the invention, the solvent is allowed to cool or evaporate over a period of from 2 to 60 minutes, preferably from 10 to 45 minutes and in particular from 20 to 30 minutes.

Diese Zeitspanne kann, wie bereits erwähnt, durch gezielte Wärmeanwendung verkürzt werden.This period of time can, as already mentioned, be shortened by targeted heat application.

Ein weiterer Vorteil des erfindungsgemäßen Verfahrens besteht in der Reversibilität der Haarverlängerung. Wünscht die Kundin bzw. der Kunde die Haarverlängerung nicht mehr, so muß die erfindungsgemäße Vorrichtung nicht - wie bei marktüblichen Systemen - durch den Friseur über die Erwärmung entfernt oder gar abgeschnitten werden,. Es ist vielmehr möglich, die Vorrichtungen problemlos aus dem Eigenhaar zu entfernen. Ein weiterer Gegenstand der vorliegenden Erfindung ist daher ein Verfahren zur Entfernung von Haarverlängerungen, bei dem mindestens eine mittels eines erfindungsgemäßen Verfahrens angebrachte Haarsträhne (erfindungsgemäße Vorrichtung) durch Einwirkung von Wärme und/oder Einwirkung mindestens eines Lösungsmittels auf das Befestigungselement vom Eigenhaar abgelöst wird.Another advantage of the method according to the invention is the reversibility of the hair extension. If the customer no longer wishes the hair extension to be removed, then the device according to the invention does not have to be removed by the hairdresser via the heating or even cut off, as is the case with conventional systems. Rather, it is possible to easily remove the devices from the own hair. Another object of the present invention is therefore a method for the removal of hair extensions, in which at least one applied by a method according to the invention hair strand (device of the invention) is replaced by the action of heat and / or action of at least one solvent on the fastener of the own hair.

Das erfindungsgemäße Verfahren kann sowohl von professionellen Friseuren als auch in der Heimanwendung durchgeführt werden. Besonders einfach gelingt das Verfahren, wenn dem Anwender alle zur Durchführung des Verfahrens nötigen Bestandteile applikationsbereit zur Verfügung gestellt werden. Ein weiterer Gegenstand der vorliegenden Erfindung ist daher ein Kit-of-parts, umfassend in einer gemeinsamen Umverpackung
