Suggestions on something to help my edges grow back?

Hello! I have about 3c-4a hair and I usually wear my hair in buns. In my pictures it's shown my hairline and how it isn't completely even and it's thinning a little. Any suggestions on how to grow them back? Thank you!

I've read where people massge Jamaican black castor oil around their edges to help them grow back. It's not a quick fix, but I think you might notice improvement in about a month.
