A trim might help how it looks.
I'd stay away from coloring it.

What helps me when I want my hair growth to speed up a bit is
One Biotin supplement daily.
One tablespoon of black strap molasses daily.
One teaspoon of FOOD GRADE diatomacious earth (mix with juice or water and drink it down) daily.
My hair growth will increase from 1/2 inch per month to 1 inch per month.
Not only that but my finger/toe nails will grow like crazy, too.
The down side? - hair grows rapidly everywhere - underarms and legs, too.
