Patent Application

The present finding relates to a method for dyeing/bleaching hair, and to a relative applicator tool.
Operative methods are known for dyeing hair, which provide the use of aluminium foil strips, end wraps in various materials, and/or also plastic caps, etc., onto which the hair is laid during dyeing/bleaching, as auxiliary accessories for the hairdresser.
For example, in the case of using aluminium foils, bleaching is obtained by a method which provides a succession of steps substantially consisting of sectioning the hair to be dyed/bleached by means of a tail comb; forming the lock; arranging the lock on the aluminium foil strip; depositing a dyeing fluid or gel onto the lock; protecting the dyed/bleached lock by, for example, superposition of a protective sheet, or by folding the lock on itself, with the lock contained within the fold; waiting for the penetration of the dye into the hair structure; and, finally, washing the hair with removal of the strips and final drying of the dyed/bleached hair.
A completely similar technique provides, as a replacement for the aluminium foil, the use of a transparent plastic material sheet. However, notwithstanding the different nature of the material constituting the strip, the dyeing/bleaching operations proceed in a substantially similar manner to those of the preceding case.
The main drawbacks suffered by all the methods of the prior art come from the fact that, between the lock of hair and the sheet with which the lock is associated, there is a continuous possibility of a relative movement which considerably affects the final result of the treatment during the dyeing/bleaching operations.
In fact, the possibility of a relative movement between the lock and the strip implies that the final dyeing/bleaching, i.e., the aesthetic properties thereof, for example, in terms of tonality, dye uniformity, accuracy of the aesthetic dyeing, depend in a highly relevant manner on the hairdresser's professional skills and his/her creativity of the moment.
Furthermore, the inherent opacity of the aluminium foil, or the equally opaque materials that are used, implies the further drawback of considerably reducing the possibilities of controlling the colour development during the step of waiting for the penetration of the dye into the hair structure.
In fact, since the dye penetration is susceptible of considerably varying as a function of several parameters, such as nature, structure, natural colour of the hair, sex of the subject undergoing the dying treatment, etc., the impossibility of visually checking the progression of the dye penetration leaves some degree of randomness in the final result, which result, again, depends in a highly relevant manner on the hairdresser's professional skills.
Therefore, object of the present finding is to obviate these drawbacks by providing an operative method, which: is easy to use; has a sure aesthetic value; is highly rapid and inexpensive to be carried out; which method can therefore be successfully implemented also by not particularly skilled hairdressers.
The advantages of the finding will be more clearly apparent from the following detailed description, given with reference to the accompanying drawings, which represent a merely exemplary, non-limiting embodiment thereof, in which:
Referring to
The first 3a and second 36 strips are side by side and arranged above the third strip 3c.
As regards the material constitution of the strips 3a, 3b, and 3c, the first two strips 3a and 3b are preferably made of a transparent plastic film, while the third strip 3c is made of a card or an equivalent, opaque material.
The plastic film can be produced in multiple different materials, all of which are fungible. The use of a PVC film, having a thickness ranging between about 80-100 microns, was found to be particularly satisfactory. However, this shall not be meant to be limiting, but only as a way of indication example, since other plastic materials having similar characteristics can be used in an equivalent manner.
The plastic film is provided, on a face thereof—the one facing towards the third layer 3c—with an adhesive material layer, of a removable type, identified by 7. An acrylic-based emulsion adhesive has proven suitable to a preferred use for the objects of the present finding.
The above-described tool 8 allows implementing a method for subjecting the hair 1 to the dyeing/bleaching treatment, the fundamental bases of which are schematically illustrated in the succession of
In
In
In order to carry out the application steps of the strips 3a and 3b to the hair 1, it is sufficient to gently pressing the strips 3a and 3b against the hair 1 to be dyed/bleached.
More particularly, from the observation of
Subsequently, the hairdresser provides to turn over the strip 3 with the lock 2 adhering thereto [
In this step, since the hair 1 is stationary, the hairdresser can create all the desired patterns in a highly efficient and rapid manner by, for example, a selectively variable application of the dye in the longitudinal direction 51 of the lock 2.
In
lf, as stated above, at least the strip 3b which is intended to the longitudinal application to the hair 1, is made of a transparent material, during the steps of
From
It is completely apparent that, if a still higher control of the progression of the dye absorption is desired, it is sufficient that also the third strip 3c of the tool 8 of
It is apparent that the use of the third layer 3c as a protection element for the treated lock 2 represents one of the operative possibilities available to the hairdresser; since it is apparent that, also without using the third strip 3c, if the length of the hair 1 and the adhesive strips 3c allows that, it is also possible to implement the protection step by simply carrying out a folding and superposition of the strip 3b which is applied longitudinally to the lock 2 of hair 1, in order to subsequently have a fully front/back visibility of the lock 2 retained within the fold,
The finding fully achieves the above-described objects, allowing a dyeing method which is completely innovative, which allows selecting, isolating, and dyeing with a high accuracy amounts of hair which are as reduced and random as desired. A number of advantages are also provided by the inherent features of the support 8.
In fact, since the hair 1 are stationarily and firmly retained by the support 8, as well as removably, when appropriate, the dyeing/bleaching treatment can be also carried out by several and selectively variable dye applications along a longitudinal direction 51 of the lock 2.
This feature allows to any not-so skilled hairdresser to be able to advantageously operate by a single, simple, and rapid movement in order to select, isolate the hair 1, and constrain them to the strip 3b; and, as advantageously, to be able to create particular decorations of different colour tones along the entire length of the hair 1. That allows obtaining highly accurate decorations and high aesthetic effect results.
Still another advantage, related to the fact that the locks 2 can be positioned with a high accuracy on the strips 3b, while being able to maintain the position thereof unaltered during the dyeing treatment, is that it allows establishing metric references, upon positioning the hair 1, which references allow successfully replicating with a high accuracy, by the dyeing treatment, the desired aesthetic patterns also at a later time, from a dyeing treatment to the next one.
In fact, it is possible to achieve both a highly uniform, diffuse colour on the entire hair length, which is otherwise difficult to achieve and replicate without the aid of a tool; or to highlight the colour and its hues in a differentiated manner on the length of the lock 2, in order to reproduce the chromatic variety of the tones, which simulates natural hair 1 colour.
The finding thus conceived is clearly susceptible of industrial application; it can also be the object of numerous modifications and variations, all of which fall within the scope of the inventive concept: furthermore, all the details can be replaced by technically equivalent elements.
