How to repair Miku's wig

So i have the re-release Hatsune Miku, not the original one that first came out that has the green accents, the updated version that has the blue accents. If your a vocaloid fan then you know that when Miku was first released her hair was a green-ish blue along with the accents on her boots/arm sleeves and her tie/shirt+skirt. Well i have the one that's blue/teal themed the Miku we all know and love today. Anyway i had to remove her wig because i was starting to have to remove stray hairs and the rubber bands were getting loose so her twin tails were getting frizzy especially at the ends. I really want to keep her wig because as of right now i'll never change her character so does anyone know how i can restore it to it's original state?

It might help to post some photos if you can.

You can get some third party replacement wigs for Miku if you need to. Honestly I think her nicest wig is Ribbon Girl, but it's dumb how expensive it is to buy just the wig. Lots of wig makers make wigs in her color though.

Could always use a hair heat protector spray to flatten the fly always, and got2b to prevent further “dead ends” 

I would recommend taking out the elastics (cutting them if you need to) spraying the wig with the hair protector (or even water really) comb through it bottom to top to get rid of tangles, and lightly using Got2b to let the hair form together and not get frizzy, or prevent further damage. Then re adding the elastics for the tails.
