several times. Sections of the hair tresses were used in a Pressure Differential Scanning Calorimetry (HP-DSC) test and compared with Virgin tress and Negative Control (Virgin tress - no treatment - Flat ironed). HP-DSC can provide insight into how a
treatment may affect deep structural changes in the hair keratin and thus the efficacy of the product in terms of heat tolerance and protection. This procedure (Figure 3) indicates that
when compared with untreated hair, the use of the anti-frizz agent increases the matrix crosslink density of hair and improves the structural integrity of ordered hair proteins. The damage linked to the use of a flat iron is lowered, and hair is better protected over repeated applications.
The anti-frizz agent versus the benchmark competition This synthetic frizz-defying solution not only provides efficacy against frizz, but the anti- frizz agent also delivers exceptional resistance to high humidity and outstanding thermal protection. These intrinsic properties empower hair care formulations, providing consumers with a natural look and feel despite the use of hot tools—such as flat irons, curling irons, or hair dryers—to style and shape their hair however they choose. Consequently, the anti- frizz agent is particularly well-suited for both straight- and curly-hair formulations. In comparison to the leading industry benchmark, which often leaves consumers with a greasy feel, the anti-frizz agent offers similar or better straightening efficacy, efficacy threshold, humidity resistance (80%), heat protection, format compatibility and no negative sensory impact (Table 1). This high- performance cationic polymer is also readily available for commercial-scale production and product development and offers freedom to operate (FTO).
Properties and use the anti-frizz agent is most optimal for preventative hair care formulations. By using the product before the hot tool, consumers benefit from maximum anti-frizz effects, damage prevention, heat protection and

smoothing benefits. However, the anti-frizz agent delivers
good efficacy if used afterward or daily, and these anti-frizz advantages last up to 3 days following treatment, depending on the solution. Leave-in creams and conditioners are the choice formulation for peak effectiveness, but styling foam can also be an option. Ultimately, the greatest advantage of
formulations made with the anti-frizz agent is that they are equally as effective as the best anti-frizz performers available on the market today but leave no oily or greasy feel behind. Additionally, the anti-frizz agent is beneficial for the increasingly desirable minimalist beauty care regimen, as it provides an enjoyable combination of excellent heat protection and anti-frizz properties at the same time. This means that consumers need not clutter their shelves with one product for
