International Journal of Cosmetic Science, Volume 48, Issue S1, Page S84-S111, November 2026.The study introduces new lab methods to measure shine, curl shrinkage, stiffness and surface wetting in textured hair. These tools help assess how products and treatments affect the hair's visual appearance and response to humidity or damage. Abstract Objective This work presents adapted methods for quantifying hair shine, shrinkage, flexibility and ...

Use of single fibre fatiguing experiments to understand breakage in textured hair Part I
International Journal of Cosmetic Science, Volume 48, Issue S1, Page S33-S47, November 2026.Single fibre fatigue testing shows three contributing factors to high breakage in textured hair. This hair type breaks far more readily under these test conditions; there is a high tendency for premature failure; and breakage is also sizably exacerbated by higher fatiguing forces associated with this hair type.

International Journal of Cosmetic Science, Volume 48, Issue S1, Page S48-S62, November 2026.Single fibre fatigue testing shows how hair breakage increases dramatically with increasing curl type because of negative trends in each of the three factors identified in our previous publication. However, sizable variability in breakage properties within any given curl type is noteworthy.

Mechanisms underlying the protective effects of San‐Bai decoction against UV radiation on the skin
International Journal of Cosmetic Science, Volume 48, Issue 5, Page 1006-1017, October 2026.Combining conventional differential expression analysis with differential network analysis offers a promising strategy to uncover the mechanistic basis of the holistic benefits provided by herbal blends. Our findings demonstrated that San‐Bai decoction modulates multiple pathways—not only those related to skin pigmentation, such as ET‐1 signalling, but

Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I
International Journal of Cosmetic Science, Volume 48, Issue 5, Page 1077-1092, October 2026.Repeated exposure to ozonated water caused cumulative oxidative changes in hair, altering structural integrity, thermal behaviour and mechanical properties. The findings reveal a distinct ozone‐induced damage profile that progresses beyond the cuticle, challenging claims of hair‐revitalizing benefits. Abstract Objective Ozone has recently been marketed

A proposal for simplifying the labelling of sunscreens
International Journal of Cosmetic Science, Volume 48, Issue 5, Page 1071-1076, October 2026.A binary system for classifying the magnitude of protection provided by topical sunscreens is proposed and examples of potential symbols for labelling sunscreens are illustrated here. Phototesting is limited to a single area of sunscreen‐protected skin and avoids assessment of the minimal erythema dose on sunscreen‐protected skin.
