    Abstract: A process for evaluating the ionic state of the surface of keratin fibers, especially human hair, which comprises taking at least one sample of fibers from the fibers to be evaluated, contacting the sample with an acidic solution of at least one acidic or basic dyestuff, assessing what, if any, change in the color of the solution has taken place and attributing the ionic state to the surface of the fibers accordingly.

    Abstract: Process for dyeing keratinous fibres, comprising the step of applying to these fibres at least one composition A containing, in a medium appropriate for dyeing, at least one mono- or di-hydroxyindole the application of the composition A being preceded or followed by the application of a composition B containing, in a medium appropriate for dyeing, at least one quinone derivative chosen from ortho- or para-benzoquinones, monoimines or diimines of ortho- or para-benzoquinones, 1,2- or 1,4-naphthoquinones, sulphonimides of ortho- or para-benzoquinones, alpha , omega -alkylene-bis-1,4-benzoquinones, or 1,2- or 1,4-naphthoquinone-monoimines or -diimines; the mono- or di-hydroxyindoles and the quinone derivatives being chosen such that the oxidation-reduction potential difference DELTA E between the oxidation-reduction potential Ei of the mono- or di-hydroxyindoles, determined at pH 7 in a phosphate medium on a vitreous carbon electrode by voltametry, and the oxidation-reduction potential Eq of the quinone derivative determined at pH 7 in a phosphate medium by polarography on a mercury electrode and relative to a saturated calomel electrode is such that DELTA E=Ei-Eq

    Abstract: Apparatus for measuring the secretions of sebum of a skin sample of a living subject comprises a frosted glass plate spring urged to project from a casing (using a calibrated spring). When pressed against the forehead of a living subject the frosted plate retracts yieldably to collect sebum under reproducible conditions. A reference scale inside the casing of the apparatus is illuminated from a known light source and is observed from outside by looking through the greasy plate. The sebum secretion is measured by changing the position of the scale, or changing the line thickness of a reference mark on the scale until a sharp, fine image of the reference mark can be seen.
