[ UPDATED, NEW RAINBOW!! ] Unicorn Vomit! [ Slightly pic heavy ]

I used an old [clean] tooth brush. I started with red, and rubbed it up and down a bit. That both got the dye to reach all the hair, and back combed it just the tiiiiiiniest of bits at the same time. That broke up the line a ton.
The one thing I didn't want was an obvious line. That's what I was scared of most, and it was a massive relief when it dried and there wasn't a proper line.

My only regret is that I wish I had taken into account hair growth. A fringe needs cutting pretty often, so as it gets cut the purple and possibly blue is going to dissapear. I'm going to try shifting all the colours further up as it fades out so I don't have to lose half the rainbow. I could have kicked myself I felt so stupid. >.<

Or reverse the rainbow with the growth 😀

that looks so amazing

Awesomeness!!!  I'm way to chicken to try this.  i know i would spend a day doing it and probably completely goof it up.

How about taking it into the sides a bit and having the blue and purple to the bottom? That way you have the whole rainbow still.

It looks strange, definitely not rainbow-y. It's easy to just dye it further up, though. I've been using editing software to try and see my options. xD I'll let you guys know if I manage it or not.

That means bleaching my roots, which... Well, I never do. Just because I don't want to, I'm quite fond of the roots look if I'm honest. xD

Seriously though it'll be fiiiiine. 🙂

Stunning!

Your hair is beautifulllll, ahh I'm so envious ;D you rock it c:
