<p>Method for assessing damages of keratin fibers using a cationic fluorescent compound comprising a cationic ammonium group and being free of carboxyl and/or sulfonyl groups and method for comparing the damages of different keratin fibers using said cationic fluorescent compound. Said methods are useful for quantitatively and/or qualitatively assessing the degree of damages of keratin fibers and also to compare the damages of fibers of different origin, different portions of fibers and/or fibers treated with different cosmetic, chemical and/or mechanical treatments. Said methods are also useful for supporting advertising claims about the superiority of a composition and/or a treatment versus others.</p> |
