Wella Color Charm Liquid Haircolor, 9N/911 Very Light Blonde, 1.4 oz

I read SO many reviews/watched videos before trying T18 on my brown hair w/ blonde highlights. Did highlights myself, didn't leave bleach on long enough, ended up with brassy orange highlights. I was so scared that T18 would turn my highlights white, or lighten my brown base colour. Finally did it this week and I love it. I mixed it with a 20 developer, left it in for 20 mins (could have gone another 10 mins) and my highlights turned a very natural ashy blonde that blended really well with my base colour. They darkened a bit, which for me was great. In case you're not sure whether to try it, I say go for it. So glad I did! Also - only used about a third of the bottle so more for next time!

HIGHLY recommend!! My natural hair is medium brown and I had been steadily adding blonde to it, then decided to just bleach my whole head. It came out a horrible yellow-orange and was super brassy. I saw this on YouTube and decided to give it a try with the T18 and cream developer and it took all the brassiness out, leaving it a cool, silvery-blonde! I left it in for 30 minutes, so there was a little purple in my hair that had already been bleached more frequently, but I think it looks cool, most people told me they didn't even notice and they thought it was more white than purple—plus it will wash out in a few washes anyway. I recommend buying two boxes of the toner, especially if you have long hair, because I JUST made the cut with the one box and I only have a collar bone-length bob. I will probably buy a second box and just do a spot treatment on some of the roots that didn't get enough of the toner.
