## Strength

### Strength X

Parameter ID: `HAIR_TOOL_CURL_STRENGTH_X`

### Strength Y

Parameter ID: `HAIR_TOOL_CURL_STRENGTH_Y`

These curves let you adjust the strength of curl along the length of the guides. The preset curves result in a strength of 0 at the guide roots, and a steadily increasing strength in the direction of the guide tips.

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).
