Passion twists are a type of hairstyle that involves twisting two strands of hair around each other to create a rope-like effect. They are typically worn by African American women and can be styled in various ways, including updos and down styles. Passion twists can be made using synthetic hair or human hair, and the length of the hair used will determine how many passion twists are needed to achieve the desired look. For example, if you are using 12 inches of hair, you will need four packs of passion twists.
