What is the term for one oblong followed by a row of pincurls?

The correct term for one oblong followed by a row of pincurls is known as a ridge curl. This technique involves creating a series of waves that give the hair texture and a rhythmic appearance. In a ridge curl, the oblong shape serves as the base, while the pincurls placed behind it help form the waves. This is commonly used in various styling formats to achieve a polished and professional look, often seen in classic hairstyles.

The other options describe different types of curls or techniques. A spiral curl refers to a curl that is formed in a vertical position rather than a horizontal row, giving a coiled appearance. A pin curl is simply a single curl formed and secured against the scalp, and a flat curl is characterized by being placed flat against the head rather than forming ridges or waves. Understanding the distinctions in these terms is crucial for effective hairstyling and applying the right techniques in salon practices.
