My Eyebrows Are Partially Gray

Some of my eyebrows are gray

those eyebrows have two colours on them. they are dark at the end and then they drastically turn white towards the root. what would it mean? also, the new little eyebrows seem to be dark.

Eyebrows gray like other hair. There is little you can do about the graying other than using pencils designed for graying eyebrows or hair.
