Another name for an on base curvature pincurl is:

The term "on base" in relation to a curvature pincurl refers to how the curl is positioned in relation to the base of the hair strand. An "on base" curl is created when the hair is rolled directly onto the base, resulting in maximum volume and strong hold. This technique is known as "no stem" because there is no portion of the hair that is left unwrapped or free from the roller, meaning the curl starts right at the scalp.

This positioning allows for a tight curl with a lot of bounce, which is ideal for styles that need lift and definition. In contrast, other types of pincurls—such as half stem or off base—allow for varying degrees of relaxation and movement in the curl. Therefore, understanding the distinctions between these terms is essential for hairstyling execution, as each produces different curl characteristics which can dramatically affect the final hairstyle.
