ABSTRACT:
FIELD OF INVENTION
This invention relates to hair manipulation and to devices for assisting hair manipulation.
BACKGROUND OF THE INVENTION
Human hair grows. If left uncut, it can grow to quite a considerable length. While long hair may be considered attractive, it is sometimes inconvenient and accordingly those who have long hair often seek from time to time to restrain it in some way. The technique of manipulating individual locks of hair into one or more plaits and securing the end of the plait remote from the head against unravelling dates back to prehistoric times. So likewise does the use of one or more combs (the comb is a very early invention) to secure the hair in some sort of bundled or folded configuration. Over the centuries, an enormously wide variety of pins, clips, slides and other devices have been used to secure hair above a certain length in a desired configuration.
The use of such devices, while very common, does not always give the desired aesthetic effect. Often it is desired for the hair to be held in a given configuration without appearing to be so held. For this purpose, various pins and grips are known which are coloured to match the hair colour and which may be inserted in unobtrusive fashion, but inserting them skilfully so that they remain unobtrusive and, in particular, so that they do not tend to slip, either rendering them visible or no longer fulfilling their intended purpose, or both, requires skill and practice, as well, of course, as a supply of pins or clips.
SUMMARY OF THE INVENTION
I have now found that such is the mechanical strength of hair that relatively large locks of hair may be held in place by using relatively small quantities of hair to hold them in place. Such fixation is desirably not permanent, nor should it be accomplished by knotting small quantities of hair around larger locks of hair. However, by constructing a loosely tied configuration, hair may be held in place for an adequate length of time against the normal forces disturbing the lie of the hair such as normal movements of the head and without prejudicing the ability of the owner of the hair, or an assistant, to comb the hair out so that the individual hairs are no longer entangled to a degree holding the hair in a position otherwise than its natural fall.
According to a first feature of the present invention, there is provided a method of retaining hair in a desired configuration which comprises manipulating a group of hairs to lie substantially in the desired position and then solely differentially looping a plurality of hairs from that desired group, or lying adjacent that desired group, through and/or around the group to an extent solely sufficient to hold the group in the desired position when the manipulation is released.
Differential looping, i.e. producing a large number of differently lying loops each of perhaps one or two hairs, and of different lengths of loop extending through different pathways within the mass of hair it is desired to hold in place, can be effected simply by manual manipulation of individual hairs or groups of a few hairs, for example using some sort of hook or like device, but if a reasonable looking final result is to be achieved, it requires very considerable dexterity and a great deal of time, in particular to produce the desired semi-permanent holding effect. Numerous individual manipulation s are needed, and this is impractical. A further problem is that when manoeuvring individual hairs into loops and moving the end of the loop it is very easy to overstretch the hair and break it, which is undesirable. It is also difficult to achieve an even effect, i.e. an even visual appearance to the final structure.
Accordingly, and this constitutes a second feature of the present invention, I have developed a tool for effecting differential looping which can be used quickly and simply to achieve the desired result.
Thus, according to a second feature of the present invention, there is provided a hair manipulation tool consisting of an elongate member, preferably of constant cross-section, and which is characterised by an exterior surface of roughness and resilience such that when passed through a lock of hair in a direction substantially transverse to the direction of the hairs in that lock, it will entrain hairs within the lock and pull them into loops until the tension in each loop is insufficient to break the hair, but sufficient to release the loop from the surface of the elongate member and leave it in place as a loop extending along the path traversed by the elongate member.
If such an implement is passed through a lock of hair, its surface entrains hairs, pulls them into loops and then releases them once the tension increases past a certain point. This occurs many times as the implement is passed once through the lock, and repeated passes in different directions quickly produces within the body of the lock a complex multiply looped structure which, while releasable on firm but gentle manipulation of the lock is nevertheless sufficiently stable and load-bearing to hold the lock in a desired position for some time. The more the looping, the longer the time.
