    • According to this process, (a) a compound capable of entering the surface interstices of the keratinous fibres is chosen; which is capable of producing, in an aqueous medium, a solution which is colored naturally or capable of being colored by a development, and capable, under the conditions of the process, of being stable and maintained at a pH such that no ionic charge appears; (b) an aqueous immersion solution containing the compounds chosen is prepared; (c) a specimen of the fibres to be studied is immersed therein to produce an "uptake" of the compound on the fibres, which is a function of their surface state; (d) the specimen is withdrawn from the solution and the excess of solution saturating the fibres is removed; (e) the compound present on the fibres is extracted by immersing the latter in at least one aqueous bath at the same pH as that of the aqueous immersion solution to obtain an extraction solution which is colored or whose color is developed in a step (f); and (g) the state of the surface of the fibres is deduced from the quantity of the compounds present in the extraction solution.

    • A process for assessing the state of surface oxidation of keratin fiber(s), especially human hair, which results following treatment with, inter alia, peroxides and bromates. This process involves applying a porous support to the wet fiber(s) to be assessed, which support has previously been impregnated with an oxidation indicator which is a solution of iodide ions, the normality of which is from 0.2 N to 10 N, the solution also containing from 20 g/liter to 200 g/liter of solubilized starch in a buffered acid medium, and, while the porous support is in contact with the fiber(s), applying to the support a solution of a strong acid, as developer, and subsequently removing the support and examining whether or not there has been a change in the initial coloration of the support.
