“…As a result, the length of the FI swatch was also reduced. The FI hair looked close to the C hair, as it regained all the original curls after the first shampoo Fibers 2022, 10, 13 9 of 14 wash. As mentioned earlier, flat ironing only straightens the hair temporarily as it only involves alterations of hydrogen bonds and salt linkages [24]. As the FI hair regained most of its original curls, the length of the swatch decreased and became close to that of control hair.…”

“…The FI hair, on the other hand, is just straightened due to the mechanical force and the heat applied through flat ironing, which involves rearranging hydrogen bonds. However, the newly formed hydrogen bonds from using a flat iron (heat and mechanical treatment) are susceptible to humid conditions, and the hair reverts back to its original state over time [24]. Moisture (65% RH) present in the conditioning room is known to easily plasticize the FI hair, causing them to curl and fluff-up [25].…”

A major drawback of current hair styling treatments is their use of toxic chemicals, such as thioglycolates, sulfites, formaldehyde, and others. Exposure to such chemicals is not only harmful to hairstylists but also to the millions who routinely receive hair treatments. The present research discusses the development of a benign sucrose-based crosslinker consisting of aldehyde groups to stabilize hair via crosslinking amine groups in keratin. ATR-FTIR and 1H-NMR were used to confirm functional groups on sucrose. Hair straightening was carried out by crosslinking via flat ironing. Crosslinked hair swatches were hung in a high humidity environment and subjected to repeated washings with shampoo to characterize the permanency of the treatment. Hair straightening through crosslinking was found to be durable to high humidity and repeat shampoo washings. The tensile characteristics of hair, such as fracture stress, strain, and Young’s modulus, were unaffected by the treatment. SEM images showed no damage to surface scales. The sucrose-based crosslinker could be used to create curls in straight hair as well.
