Which pin curl base placement allows the most movement and least amount of curl?

The correct answer is the full stem placement for pin curls, which allows for the most movement and the least amount of curl. In a full stem pin curl, the curl is attached to the hair with a considerable amount of space between the base of the curl and the scalp. This distance allows the hair to have more flexibility and movement as it is not anchored tightly to the head.

Because the curl is not closely set to the scalp, it can produce softer waves or body rather than tight curls. This technique is ideal when a stylist desires a more relaxed and mobile hairstyle, as it permits the curls to fall more naturally.

The other placement options offer varying degrees of hold and curl definition. For instance, half stem pin curls and closed stem pin curls create tighter curls because they position more of the curled hair nearer to the scalp, limiting movement. Half base placements also produce a firmer curl compared to full stem placements because they provide some lift at the base but still create a stronger curl definition than the full stem option.
