The arc base pin curl is recognized as the most commonly shaped base due to its ability to produce soft, natural waves and movement in the hair. Its design allows for a smoother transition from the curl to the hair, creating a more blended and elegant finish that is desirable in many styles. This shape also works well when creating volume at the roots and is versatile enough to be used on various hair lengths and textures.

In contrast, the square base is generally used for a more defined curl and can create a stronger wave pattern. The triangular base, while useful for creating more lift, has a more pointed shape that can result in less uniform curls. The rectangular base serves specific styling purposes but is not as commonly used for achieving a broad range of styles compared to the arc base, particularly for those aiming for softer waves and curls.
