Effect of Hair Damage on Colour Uptake and Colour Fastness

Abstract

Furthering our previous study on damage to hair, this paper investigates the effects of three different hair damaging treatments on colouration effects with an oxidizing semi-permanent colourant. The three damaging treatments are (i) sunlight (simulated by Xenon light), (ii) perming and (iii) bleaching. The colour uptake was evaluated differently with a conventional method by CIE L*a*b* system of equation.

In addition, the colour fastness properties of coloured hair to different simulated daily activities, such as (i) hair washing, (ii) hair perming, (iii) sunlight exposure and (iv) swimming in sea water were also examined.

Based on the experimental results, it can be concluded that hair treatment with bleaching can improve colouring performance because melanin is eliminated from hair. At the same time, the colour fastness properties of coloured hair under different colour fastness testing conditions becomes worse with respect to the increasing degree of damaging treatment
