September 2020 in “Biopolymers” This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.
June 2017 in “University of the Arts London Research Online (University of the Arts London)” This study compared the effects of three compounds on structural and sensory benefits for bleached hair when applied with or after bleaching, observing that their application may mitigate bleaching-induced damage.

June 2018 in “Cosmetics” This study found that using an aqueous solution of AMPD in hair bleach reduced both hair damage and odor compared to ammonium hydroxide.
May 2026 in “International Journal of Cosmetic Science” This study found that UV radiation exposure during a simulated Brazilian summer caused more significant mechanical damage to natural hair than bleaching, although both caused comparable structural alterations, with double bleaching leading to the most severe protein degradation.
