# Set Roots

> **Note:** **What is it about?**
>
> This page describes the **Set Roots tool** for hair in **Cinema 4D**. It replants guides that have lost their connection to the scalp geometry, anchoring their roots back onto the nearest surface — the repair tool after unrooting or topology changes.

Occasionally, it can happen that guides lose their link to the hair-covered surface (see [Unroot guide](https://help.maxon.net/c4d/en-us/Content/html/OHAIR.html.md)). Use this tool to replant those guides. The guide roots will then be planted onto the nearest surface (of the object to which the Hair object is assigned).
