Abstract: A method of testing a plurality of hair strands (locks) with chemical formulations, either with cut and taped (at root end) hair strands, or with hair strands wrapped on a rod or roller, securely fastened in the clip of a small folding clipboard Tester, comprising a clip at the top of a dark colored inside back surface of Tester for testing, examining and comparing hair strand samples, and a vertically hinged light colored front, for when this light color facilitates examination; there being 1/2 inch space between clip and cover to lift strands onto cover while still fastened in clip. Keeping records of the multiple strands, clients, tests, products, formulations, timings, desires and results involving a complete multiple Hair Test Record Card, its reverse side having a release or waiver; which is incorporated in a transparent pocket on the inside back of the cover, which also has a small identification card and pocket for student or owner.

Abstract: A hair treating device includes a pliable liquid impermeable sheet adapted to be placed in underlying relation to selected strands of hair during application of a hair treating substance to the selected strands and is of sufficient lateral width to extend laterally outwardly from opposite sides of the selected strands. In one embodiment, the pliable sheet is of sufficient length to enable it to be folded upon itself and substantially overlie the selected hair strands. The pliable sheet has discrete domains of alternating magnetic polarity defined therein operative to releasably maintain the folded layers in juxtaposed relation through magnetic attraction therebetween and establish a liquid seal about substantially the full periphery of the treated hair strands.

Abstract: A conforming valved cervical cap assembly is provided with an elastomeric inner layer molded and cured in situ adjacent the exocervical surface of a cervix uteri. The inner layer is wettable, non-porous and matingly fits and resiliently complements the exocervical surface. In order to prevent the molding material from clogging or otherwise impairing operation of the valve, a valve cover is detachably connected to the valve during molding and curing.

Abstract: Appliances for the partial dyeing of hair are intended, for example, to serve for dyeing individual strands of hair, in order to achieve stylish effects as a result of the color contrast.To ensure that the appliance is mastered even by less experienced staff and that dyeing is simplified and speeded up, the appliance has at least one guide prong (14), which is provided in its interior with a dye-feed bore (16) and on at least one side, spaced at a distance from the prong end (19), with at least one peripheral dye-outlet orifice (21). The appliance also includes a dye container (3), which is connected to the dye-feed bore (16) of the guide prong (14) and out of which the dye can be expressed by means of pressure, and at least one masking prong (22) which is located spaced at a distance from the guide prong and covers hair not to be dyed and which is located, approximately transversely to the working direction of the guide prong (14), next to the latter.
