Quantification of hair bleaching using a photoactivated atomic force microscopy

23 January 2022 • 5:30 PM - 7:00 PM PST | Moscone West, Lobby (Level 3)

Abstract

Excessive bleaching can cause changes in the amino acid composition as well as the surface structure of the hair. Thus, proper hair bleaching and quantification is important to achieve cosmetic purposes while maintaining the healthy properties of the hair. Here, we propose a novel method to quantify the degree of hair bleaching at the nanoscale resolution using a photoactivated atomic force microscopy (pAFM). We demonstrated that acquiring and quantifying pAFM images of hair according to bleaching time can help determine the appropriate bleaching time. We believe that this result will help to prevent unwanted hair damage due to bleaching.
