Did Darth Vader ever learn how to prevent people from dyeing through the dark side or did he just give up after Padme died?

He found that he already knew how to prevent people from dyeing as long as he was right there in front of them. Or had a clear view of them.

However, when he wasn't around, people were free to dye as they pleased. However, due to the knowledge that Vader himself didn't appreciate people dyeing in the Empire, especially the military, most citizens kept to their natural hair colors.
