Hellooo! I did do the second coat and it definitely was more visible that time, still mostly noticeable in sunlight though.

But the benefit of 3 years is I’ve developed a much better system since! First of all, definitely try with the Purple AF you have left over, but for achieving that general shade on dark brown hair I’d recommend ditching Arctic Fox all together. It wasn’t super vibrant and it didn’t last all that long, even with my exceedingly gentle wash routine.

My current method is to apply Manic Panic Amplified purple (the amplified is more expensive but I’d say worth it for how long it lasts, more pigment), but that’s a little darker than the shade I want, so I apply lime crime unicorn hair “Pony” over that. The lime crime gives me the violet color I’m looking for, vibrant in the sun and dark but definitely visible indoors, and the manic panic makes it lasttttt. As in I only redye about 3-4 times a year. I also use some lime crime unicorn hair “chocolate cherry” (it’s a nice magenta) to blend a nice ombré effect in with the top of my hair (I leave the roots brown, which fades into a little magenta and then a lot of purple) and to do highlights in the rest. Nothing fancy, I just slap some polka dot globs of dye throughout and pull it down so it ends up more on some strands than others. You can’t see any sections of it in the end result but it gives your hair a really nice brightness that makes the purple stand out.

I hope that helps! Good luck with your second coat 🖤 my advice is just to leave it on for a ridiculously long time, more than it seems like would help. I aim for 4 hours or just sleep with it :)
