Specifically something with brown roots if possible. I'm looking for something similar to Helena from Orphan Black (aka the nutjob in my signature photo!)

It's fairly poofy and she probably doesn't even know how a hairbrush works.

Hair with tight curls like this is pretty rare and all the cheap options I know of are dark brown or black. The closest I can think of is redeemed and recolored to blonde. In some hairs recoloring the Shading Lowlight option can sort of simulate differently colored roots but I don't own this one so I don't know if this works.

If you do intend to pick this one up you should probably wait until the black friday sale and you can probably pick it up for 125 csc (worth about one third of the current user shop sp price now).

I had no idea they had Black Friday sales on here! I'll definitely need to remember to check it out when the sales come along. Thank you!

This is a real challenge; I spent way too much time on it. :D

These are the best-matching ones, I think:

Short:

Long:

Or, if you find the colouring more important than the styling, I'd go for a Hair Salon one. Possibles: Aloop, Cu, Curled, Goldilocks, Loli, Longdreads, Longwave, Mia, Waved.
