limiting . in the drawings , the size of some of the elements may be exaggerated and not drawn to scale for illustrative purposes . the dimensions and the relative dimensions do not correspond to actual reductions to practice of the invention . furthermore , the terms first , second , third and the like in the description and in the claims , are used for distinguishing between similar elements and not necessarily for describing a sequence , either temporally , spatially , in ranking or in any other manner . it is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein . moreover , the terms top , bottom , over , under and the like in the description and the claims are used for descriptive purposes and not necessarily for describing relative positions . it is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other orientations than described or illustrated herein . it is to be noticed that the term “ comprising ”, used in the claims , should not be interpreted as being restricted to the means listed thereafter ; it does not exclude other elements or steps . it is thus to be interpreted as specifying the presence of the stated features , integers , steps or components as referred to , but does not preclude the presence or addition of one or more other features , integers , steps or components , or groups thereof . thus , the scope of the expression “ a device comprising means a and b ” should not be limited to devices consisting only of components a and b . it means that with respect to the present invention , the only relevant components of the device are a and b . similarly , it is to be noticed that the term “ connected ”, used in the description , should be interpreted as possibly meaning that two or more elements are either in direct physical or electrical contact , or that two or more elements are not in direct contact with each other but yet still co - operate or interact with each other . reference throughout this specification to “ one embodiment ” or “ an embodiment ” means that a particular feature , structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention . thus , appearances of the phrases “ in one embodiment ” or “ in an embodiment ” in various places throughout this specification are not necessarily all referring to the same embodiment , but may refer to different embodiments . furthermore , the particular features , structures or characteristics may be combined in any suitable manner , as would be apparent to one of ordinary skill in the art from this disclosure , in one or more embodiments . similarly it should be appreciated that in the description of exemplary embodiments of the invention , various features of the invention are sometimes grouped together in a single embodiment , figure , or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various inventive aspects . this method of disclosure , however , is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim . rather , as the following claims reflect , inventive aspects lie in less than all features of a single foregoing disclosed embodiment . thus , the claims following the detailed description are hereby expressly incorporated into this detailed description , with each claim standing on its own as a separate embodiment of this invention . furthermore , while some embodiments described herein include some but not other features included in other embodiments , combinations of features of different embodiments are meant to be within the scope of the invention , and form different embodiments , as would be understood by those skilled in the art . for example , in the following claims , any of the claimed embodiments can be used in any combination . in the description provided herein , numerous specific details are set forth . however , it is understood that embodiments of the invention may be practised without these specific details . in other instances , well - known methods , structures and techniques have not been shown in detail in order not to obscure an understanding of this description . the invention will now be described by a detailed description of several embodiments of the invention . it is clear that other embodiments of the invention can be configured according to the knowledge of persons skilled in the art without departing from the true spirit or technical teaching of the invention , the invention being limited only by the terms of the appended claims . in the following examples , the electrostatic charges are predominantly shown as being arranged around , or at , the ends of the hair building solids . this is due to the nature of electrostatic charges collecting , or being concentrated , at such places . however , it should be understood that the arrangements shown are not limiting as electrostatic charges will also be formed or maintained , in some embodiments , in other places either as well as , or instead of , at the ends . although no individual coatings , as such , are represented , it should be understood that the solids depicted may include one or more such coatings on all or at least a portion of their surface . such coatings may penetrate the surface of the solids . fig1 show a hair building solid in the form of an essentially flat rectangle , such as a length of tape . alternatively , the solid 10 shown in fig1 could be one side of a substantially rectangular box - shape such as shown in fig1 , or one side of a tube or cylinder as shown in fig5 . an electrostatic charge is arranged substantially across the entire surface of the solid having a positive polarity . alternatively , the solid 20 may have a bipolar charge , which is also dipolar in nature , as shown in fig2 , such that there is a negative charge at one end of the solid and a positive charge at the other opposite end . another alternative , is that the solid 30 has a bipolar charge in that an electrostatic charge is arranged at either end both having the same polarity which could be either positive as shown or negative ( not shown ). the solid 40 in fig4 is substantially arcuate in form having a positive charge at one end , a negative charge at the other opposite end and a discrete positive charge arranged at an approximate mid - point along one side . the form of the solid 40 is substantially semi - circular . the cylinder or tube 50 shown in fig5 has a positive charge at one longitudinal end and a negative charge at the other opposite end . fig6 shows another arcuate form of solid 60 , however , this one is more crescent in shape than the one shown in fig4 . it has two substantially tapered ends 62 where the electrostatic charge is provided , one being positive and the other negative . a similar solid 70 is shown in fig7 , however , it has only one tapered end 72 , the other , opposite , end 74 being blunt . again , a positive charge is provided at one end ( the tapered end 72 in this figure ) and a negative charge at the other ( blunt ) end 74 . it is also possible to produce solids 80 having a notch 84 in one end , the other longitudinal end 82 being without such a notch 84 , although it is possible for notches to be provided in both ends . in this embodiment , a charge of one polarity may be provided within the notch 84 while a charge of another polarity may be provided on the surface surrounding the notch 84 . a charge may be provided at the other longitudinal end 82 of the solid 80 which is shown as being positive . fig9 shows how solid 90 may be rhomboid in shape . the view in fig9 may be of a substantially laminar - like material , such as a tape , or the side view of a solid 90 having a thickness , which although not shown , may be of substantial dimension such that the solid would not be considered laminar - like , but would be more fibre - like . again , a dipolar charge is shown with a positive charge at one end and a negative charge at the other end . some solids 100 may be bifurcated . this may occur at only end , as depicted in fig1 , at both ends ( not shown ). the bifurcation may comprise of two tines 102 . a charge may be present on the tines 102 and therebetween . these charges may be the same polarity or may have different polarities . in the example shown the tines 102 both have a negative charge , however , the charge shown along the sides of the solid away from the bifurcated end has a positive charge . another possibility is that the solid 110 may include a concave portion 112 . this may be provided in one end of the solid or may be provided on the longitudinal side of the solid . a charge of one polarity may be present within the concave portion 112 and a charge of another polarity may be present on the surface of the solid 110 . the concave portion 122 may be provided all the way around a solid so as to form a waisted portion such as is shown in fig1 . the charge within the waisted portion 122 may be of one polarity and the charge at other portions of the surface of the solid 120 may be of another polarity . for instance , there may be a positive charge in the waisted portion 122 and a negative charge arranged at the extreme ends of the solid 120 . a solid 130 having a parallelepiped form is shown in fig1 . by contrast , a substantially oval form of solid 140 is shown in fig1 . this may be substantially laminar and tape - like or may be like a rugby ball which has been stretched in the axial direction . both of these solids 130 , 140 have a positive charge at one end and a negative charge at the other end . in use , the electrostatically charged solids may be attracted to a user &# 39 ; s hair and / or skin so that they are substantially retained in place . it is useful to be able to encourage the formation , polarity and distribution , of charges on the solids . this allows for a greater degree of control of the product in use and may allow for the tailoring of charge types on an individual basis as possibly dictated by hair types , environment and other such factors .
a hair building solid comprising a coating , wherein the coating facilitates the formation of a dipolar electrostatic charge on the surface of the coated solid .
