I think it looked okay. Yes I know Hasbro made the mane and tail in the wrong colours and I don't have any rehairing tools.
I just cut her hair halfway up her leg. Stuck her under a tap with cold water, put shampoo and conditioner, style it (I wrapped her hair around her leg) rinse it with cold water, then hot water than cold water again.
I also stuck some green hair into her tail hole. And twisted it so the purple is on top. I tried to stick some orange and yellow, but the hole is to small.
Then I let her hair dry overnight and I cut it her mane and tail in the morning.
It was hard because her wings were in the way, but I forgot I could move her head.
