Last December I changed my hair colour from natural dark brown to a light blonde and I haven't looked back since. I love the way it lifts my skin tone and lets me get away with wearing much brighter colours. Hell, it sounds like a cliche, but people even treat you differently depending on your hair colour.
But, to be completely honest here, it is a right pain up the backside to maintain bleached hair. It gets dry, frazzled and occasionally turns into a shade of Simpson yellow. It's certainly not a hair colour to go for if you prefer something low-maintenance!
One thing that's literally been a lifesaver when it comes to my bleached hair turning nasty, has been purple shampoo. And as far as purple shampoos are concerned, this one from Lee Stafford is among the strongest you can find. Even when my hair basically turned orange (hard water can make this a lot worse), this baby turned it into a beautiful shade of gold.
In fact, as it's so strong I would only recommend this to medium to dark blondes. When I had some highlights put into my hair it actually turned a light shade of purple, even though I rinsed it out immediately after applying it. Even then you only really need to use it once a week, or perhaps even every other week.
As for the conditioner, I only bought it to go with the shampoo, but to be honest, you may as well leave it on the shelf. It doesn't add any colour-correcting properties and the shampoo is strong enough anyway, so you don't really need to add any more purple for the conditioner. Considering it's a conditioner aimed at bleached (read dry and frazzled) hair, it could do with being a lot richer and more nourishing than it is.
For any bleaching accidents or hair that just doesn't want to stay that lovely shade of blonde, the shampoo gets both of my thumbs up, however.
