> This page documents the **Curl tool** for hair grooming in **Cinema 4D**. It winds selected guides into spiral curls of two adjustable types — the direct way to turn straight hair into locks, ringlets or permed styles.

Use this tool to add spiral-shaped curls to selected guides. Two types of curls are possible:

- The guides will rotate in a spiral in the direction of the guide root (**Angle** and **Tightness** settings)
- Spirals will be created around the length of the guide (**X / Y Height** and **X / Y Length** settings).

Pictured above are both curl types. The can, of course, be used in combination with each other. Left: **X / Y Height** = 0. Right: **Angle** = 0.

If you only want to create one type of curl, change the settings for the other curl type to 0.

Please note that the guides must contain sufficient guide segments to achieve a smooth look.
