I don't think you can actually do anything. It similar as what happens with saddle sores. When a rubbed area grows back white instead of the same as the rest of the coat color. One of my biggest nightmares with my horses. Luckily with a tail with time new hair should grow back the color it's meant to be.
All I can say is to let it grow back :)
