Abstract: Mehrstufiges Verfahren zur dauerhaften Verformung von Haaren, bei dem das Haar vor und/oder nach dem Aufrollen auf Wickler zunächst mit einem flüssigen haarkeratinreduzierenden Dauerverformungsmittel behandelt wird. Dieses flüssige, schwach verformungswirksame Dauerverformungsmittel vermag das Haar im Bereich der Haarspitzen zu verformen, ohne jedoch während der Einwirkungszeit die Haarspitzen zu schädigen. Anschließend wird auf die gewickelten Haare ein konsistentes haarkeratinreduzierendes Dauerverformungsmittel, das bei 30°C eine Viskosität von 50 bis 5000 m Pa · s, vorzugsweise 100 bis 500 m Pa · s, aufweist und eine gegenüber den flüssigen Dauerverformungsmittel stärkere Verformungswirksamkeit besitzt, aufgetragen. Das konsistente Dauerverformungsmittel schirmt die Haare nach außen ab und verhindert so einerseits den Zutritt von Luftsauerstoff und anderseits das Entweichen eines flüchtigen Alkalisierungsmittels, wie z.B. Ammoniak. Weiterhin wird durch die höhere Verformungswirksamkeit des konsistenten Dauerverformungsmittels eine gute Umformung des Haaransatzes ohne die Gefahr einer Überkrausung der Haarspitzen erreicht. Nach einer ausreichenden Einwirkungszeit wird das Haar ausgespült und sodann mit einer oxidierend wirkenden Lösung behandelt.
