The study investigated the impact of adding Rosehip extract to permanent wave products, focusing on hair damage and waving efficiency. It found that adding Rosehip extract improved waving efficiency in products with cysteine but reduced it in those with thioglycolate. Despite this, Rosehip extract positively affected hair treatment in both types, with cysteine-based treatments causing less damage than thioglycolate-based ones. The study suggested that Rosehip extract could enhance hair waving, but acknowledged limitations due to variations in hair thickness and application areas, indicating a need for further research on different hair types.
