Was the hair change permanent or temporary?
Did saving and reloading or switching map locations help in either case?
If not, and they happen again (or you still have save(s) with either issue), please email supportdos@larian.com.
For Windows you can use the
D:OS Analysis Tool to create a report containing system and game information, as well as your saved games. To reduce the file size, you can delete all but the appropriate save(s) from the zip.
For Mac, saves can be zipped by right clicking the folder(s) and selecting Compress, in the folder:
~/Documents/Larian Studios/Divinity Original Sin/PlayerProfiles/<ProfileName>/Savegames
