This invention rentes to a. method of straightening kinky` or wavy human hair.
An object ofthe invention is the provision? of a method, whereby thestraightening or altering CJI of the structure of kinky or wavy hair may be effectually accomplished and so that the hair will be straightened with a permanent effect.
The invention consists in a methodcharacterized by the novel and improved featuresillustrat- `ed in the accompanying drawing and hereinafter described and claimed.
1n the drawing:
Figure 1 isa side View of a device used prac- 1 tice of the present method.
Fig. `2 is an enlargedlongitudinal sectionof the device, portions thereof being broken away;
" Fig. 3 is a section taken on the line 3-3 of Fig. 2; l
Fig. 4 is a view of one end portionof the flat bar or plate` against which the hair is laid in the `straightening operation. e
The method contemplates the use of a device whose specific features are illustrated in `the drawing by way of example. "The device includes inner and outer tubular metal shells 10 and 11, respectively, each of which is substantially of oval formation with opposite sides practically flat. The inner shell 10 constitutes an oven and is longer than the outer shell 11. This outer shell 11 constitutes a cover for an electric heater 12, which is arranged inthe spacepro- `vided betweenthe shells 10 and 11. V'I'he heater 12 may be of any suitable type, which has not been illustrated in detail but which consists of` a shell of mica, heat-resisting and electrical ,insulating cement in `which the heating elementis embedded, and an outer ,asbestos coveringwhich will be disposed next tothe outer shell 11. An extension cord 13 having the usual `conductors supplies current to the heater 12. The ends of the outer shell 11 are closed by collars, 14,which are slipped over the inner shell 10 and are fastened to the outer shell 11 in any suitable manner. These collars are made of a heat-resisting and electricalinsulating material. The exten# sion cord 13 extends'through one of `the collars 14,l as shown in Fig. 2.` The device also includes a iiat elongated plate or bar 15 of metal or any` other suitable rigid material. The bari 15`isf a length to extend through the oven provided by i the inner shell 10 and is of a cross-sectional size as to leave a space surrounding the same when disposed in the oven, which space will be occupied by the hair and other accessories to be `hereinafter described. The bar 15 has a plurality of notches 16 in one end thereof to receive the cord or string for the purpose of fastening the vhair to the bar. The manner in which the device is used in accordance with the method will be described hereinafter.
The present method differs from known methods of straightening kinky or `wavy human hair which rely merely on a softening agent, pulling and stretching the hair, and then applying steam or heat, since it has `been found that hair canand stretching, andapplication of steam or heat, but that the kinks must be ironed out before or notbe straightened simply bya solution, pulling after applyingv the softening agent, and before i applying heat thereto. In accordance` with the present method, the hair is `iirst soakedwith a solution that penetrates the hair to remove all grease and oily` substance rand thus soften the hair, after which the hair is dried. After this has been done, a suitable substance is applied to the hair which acts as a softener and a protector from heat and which will not produce` steam i and is secured at the scalp end by tying the same with a cord-or tape. extended in the notches 16 in the end andfsides of the bar 15, as shown.` Next, the absorbent material is dipped in a solution `containing an ingredient tol cutthe solution `previously used on the hair and` also ingredients to soften the hair. The absorbent material is then `wrapped around the bar15 and the hair laid against the same in straightened condition.
Nextfa'heat-cnducting material, such as metal foil, is wrapped around on the absorbent mate# rial in `such manner so that approximately `onequarter inch extends beyond `thebar at the scalp endthereof. A` felt pad is thenslipped over'the wrappings on the bar and is brought in contact with 4the scalp to protect the same from the heat, and a protecting clip of heat-resisting material is clamped over the wrappings beyond` the bar to prevent the heat fromescaping to the scalp. TheovenlO and attached.heater areplaced over the wrapped hair, and the current is turned on. Heat will be applied removing all moisture and acting on the structure of the, hair whereby it will be changed so that the hair will remain straightened with a permanent effect.
