Which type of curl is suggested along the front or facial hairline to prevent breaks or splits?

The recommended type of curl along the front or facial hairline to prevent breaks or splits is triangular base pin curls. This choice is significant because triangular base pin curls are designed to create a more natural and seamless blend with the hairline while promoting a smoother flow in the hairstyle. Their triangular shape allows the curl to lay flatter against the scalp, providing better support and minimizing tension on the hair. This is particularly beneficial in sensitive areas like the hairline, where hair is often finer and more prone to damage.

Additionally, triangular base pin curls help to avoid harsh lines or bends that could lead to hair breakage. They encourage a softer, more rounded finish around the face, enhancing the overall aesthetic while also being less likely to cause splits or breaks in the hair. In contrast, the other options—rectangular, square, or flat base pin curls—may create more pronounced bends or shapes, which are not as effective for maintaining the integrity of the hairline.
