Hi Anna,
Thank you for your question 💕
the ghd Rise Volumising Hot Brush is intended for use only on dry hair. It is a hot brush designed for styling hair and creating volume, not for drying hair. Therefore, it is not recommended to use it on wet or damp hair.
For the best and safest results, you should first dry your hair completely and apply a heat protectant product before styling. After that, you can use the brush section by section to achieve beautiful, long-lasting volume from root to tip.
Feel free to reach out if we can help with anything else 😊
