The split screen with a red X and green checkmark, and the title "Stylizacja włosów kręconych kiedyś i teraz!".

The video starts with a split screen showing a red X and a green checkmark, with the text "Stylizacja włosów kręconych kiedyś i teraz!". A woman with long, wavy dark hair is shown. The video then transitions to showing her hair styling routine, contrasting a "Kiedyś" (formerly) method with a "Teraz" (now) method. The "Kiedyś" method involves applying a leave-in conditioner and blow-drying. The "Teraz" method involves applying curl cream and mousse to wet hair, and then serum to the ends, before air-drying. The video ends with a comparison of the results, showing the difference in curl definition.
