On a recent impromptu trip to the hairdressers, I decided to butcher the crap out of my barnet by bleaching it to within an inch of its life. The original plan had been to bleach the entire mop, but my hairdresser advised that this could end disastrously - so we settled for highlights in the end. It's been a few months since I got it done and yes there are roots (which I don't mind) and it has gotten quite yellow (which I do mind). Because I don't want to spend the rest of my life bald, I'm trying not to re-bleach too frequently - so I've started playing around with colours in a bid to keep the yellow devil away.
First try was Bleach London's semi-permanent colours. I picked up this pink hair bundle from Boots - a shampoo and conditioner (which add subtle pink hints), a semi-permanent dye and a crayon/chalk for touch-ups, all for a purse friendly £16. First things first - give the crayon to a passing child (it's not great), then head to the shower IMMEDIATELY for a pink rinse. I slopped on the shampoo and conditioner as soon as I got it and the results were so darn lovely, I haven't even touched the dye yet. On the first wash - it was very subtle, by the second it had deepened into the softest, milkshakey pink. I AM A MERMAID. As you can see below, the colour's clung to certain strands more than others (the bleachiest ones), so obviously, on a block-bleach-blonde, you're going to have a more consistent colour, but I was chuffed with how mine turned out.
The only downside is that the shampoo is quite drying on my sandpaper barnet - so I'd recommend that once you've built your colour up just use them every other wash. I've also started mixing the conditioner with something more industrious to compensate - but for the price, these are cracking.
