## Curling

### X Curl

Parameter ID: `HAIR_TOOL_CURL_X`

### Y Curl

Parameter ID: `HAIR_TOOL_CURL_Y`

These curves define the effect of the guide points on the individual guides. Both curves in their preset states, in conjunction with the correct phase distortion, will result in a perfect spiral.

These graphs only have an effect on the curls defined by **X Height** and **Y Height** (i.e. curls along the length of the guides).
