Chemical over-bleaching affects both the hair's structure and its interactions, leading to a significant loss of strength and elasticity. 11,61,62 The treatment of the hair fibres with the peptides may re-establish some of the hydrogen and disulphide bonds lost during chemical treatment, improving the hair's mechanical properties. The effect of the peptides on the hair's mechanical properties was assessed through the evaluation of hair elasticity (Young's modulus) and stress at peak ( Fig. 3C). The Young's modulus results from α-keratin stretching, which is resisted by disulphide bonds and by hydrogen bonds between turns that stabilize the helical structure of the keratin. After α-keratin stretching, a transition of the keratin from α-helix to β-sheet occurs, in which the keratin chains unfold without a high level of resistance. The measurement of the stress at peak corresponds to the resistance of β-sheets to stretch until reaching the rupture point. 63–65

UNEP (United Nations Environment Programme) - Montreal Protocol Ozone Depletors - Annex C - Group I - ODPs Straightening evaluation of curly hair tresses treated with peptides in serum formulation. The efficiency of the peptides at straightening curly hair was evaluated in an alcoholic-based formulation. The effect of the formulation was computationally reproduced in a previous study regarding strong interactions between the hair and alcoholic components. 55 The peptides (PepE, PepG and KP) were incorporated into alcoholic formulations at pH 7.5 (1.5% propylene glycol, 10% ethanol, and 0.5% benzyl alcohol). Each serum formulation was applied onto the hair tresses and left in for 15 minutes. The hair straightening process was induced using a flat iron at 200 °C. The method was repeated until each hair tress was dried and straight. Then, the hair tresses were washed with distilled water and dried at 50 °C. The straightening efficiency was calculated using the above-mentioned equation. The hair tresses were then washed and shampooed 20 times. Results and discussion Characteristics of chosen peptides The modification of hair shape was the driving force for the selection of appropriately engineered peptides based on the sequences of keratin and KAPs. These peptides were selected based on a previous study of 1235 cysteine-containing peptides of all genes of human hair keratin and KAPs. 34 This study analysed the interaction of the peptides with keratin extracted from human hair, and the peptides with the best characteristics were selected for further analysis. Due to their high cysteine content and hydrophobic properties, these peptides are expected to present higher affinities towards the hair proteins. Furthermore, decapeptides are small enough to be able to penetrate into the hair cortex, but 10 to 13 amino acids residues make these peptides big enough to provide enhancement of strength and restructuring of the hair protein linkage network. 10,16,30,32 U.S. - California - Cosmetic Fragrance and Flavor Ingredient Right to Know Act - Substances in Designated Lists Chelating shampoos may not always work for colored hair. Due to their intense cleansing formula, they can fade hair color. So if your hair is dyed, bleached, or highlighted, choose one that says color-safe. Scalp Condition

Metal particles and ions from hard water, mainly copper, can coat the hair strands and cause discoloration, according to research conducted by L’Oreal in 2014. In its physical form, suppliers of acrylates copolymer describe it as white beads or as a white powder.
