How can I make my hair not so damaged?

So a while ago I got my hair permed and it got all dry so I cut it off I’d say a little over two weeks ago.

I want to redye it because its starting to look all golden and brown and that doesn’t look good with my skin tone/ eye color.

I also want it to grow out a lot more before the middle of July.

Is there anything I should be doing?
I take vitamin E pills too.
