For a lot of people with blonde hair, the perfect blonde is always hard to achieve... I quite like my natural dark blonde hair colour as it's quite ashy, but I like to have very bright blonde fine highlights to lighten it and add different tones as my own hair colour doesn't compliment my skin all that well - I'm quite pale/cool skinned so I suit a lighter ash blonde. My hair can tend to go brassy and yellow if not cared for properly, and in a perfect world I'd love the palest lilac mermaid hair... ahhh. But toning it will do fine for now!
I put this picture up on Instagram not long ago but it does need doing again as it's been several weeks. I bought 2 colours of Schwarzkopf Live Color XXL HD Ultra Brights in Purple Punk and Electric Blue to mess with. I tried this DIY toner on a bit of a whim and thought... what's the worst that can happen? So I took a small bowl of conditioner and squeezed a small teaspoon of each of the colours into it and mixed thoroughly. The mix was dark and very purple and I was maaaaybe a little scared. But what the heck. I smothered the bright purple mixture onto my whole head and put on a very unattractive shower cap for about 20/30 minutes before washing off. Despite the depth of colour of the mixture in the bowl however, I was left with this lovely and pale ashy, lavender tone with just the odd lilac streak through it. And as my hair had been soaked in conditioner for 20 odd minutes, it felt silky too.
The best thing about this is the tube is usable again and again so as long as you have conditioner your hair can always be re-toned in 20 minutes! The only thing disappointing is my natural roots didn't really take the colour as I haven't had highlights done for months now, but the lengths were just a perfect colour for me. I think I'll soon have my highlights redone though and then I'll re-tone! I suppose if you upped the dose of colour in the mix you might get an even brighter result. But I'd definitely recommend this method to tone yellowing brassy blonde hair! So easy, cheap and doable again and again!
