So, with the new craze, it's time to look at the celebrities who can pull of this difficult colour, and the ones that should just stay away.
Oh Dear! Kelly Osbourne
Back when Kelly Osbourne was trying to make it as a young rock-star (anyone remember such hits as Shut Up...), she decided it would be a wise decision to dye her hair hot pink.
I wonder what trauma brought that decision on. This Cleopatra style pink bob just isn't working is it? I bet even Kelly herself would look back at this and cringe.
This obvious cry for attention was just one of the many things a young Kelly Osbourne did before becoming the Broadway star and fashion icon she is today (who would have saw that coming?).
In recent years, she's experimented with pink and grey and actually pulled it off rather well, but she should definitely stay away from this colour.
Oh Dear! Lily Allen
Oh dear Lily. Sometimes we need a change of hair colour to spice things up a little bit, but this isn't the way to do it. Lily experimented with pink hair a few back and it was just a huge miss.
The candy floss shade works so badly with her peachy skin tone, and the bare minimum make up.
In my opinion, Lily is so much more suited to brown hair. She's dabbled in blonde a few times too, but I just think the controversial singer (or whatever else she is doing these days) should stick to her brown shades.
Oh Dear! Gwen Stefani
The 90s weren't kind to some people. I don't know what's worse about this picture, the colour or the god awful knife and fork fringe. I'm so glad Gwen realised that blonde was her colour.
This hot pink colour just doesn't do anything for me, especially on Gwen. Even if in some pictures she suited it a bit more than this one, she suits blonde a lot more, and you should always go for the colours you suit the most (right?). There's no point unflattering your look on purpose.
This is a prime example of how not to do your hair.
Oh Dear! Britney Spears
Poor Britney. I do feel slightly mean pointing out her pink wig days, but it's got to be done.
This was during Britney's breakdown year when she shaved her hair off. Whilst out in public, she often sported this very cheap pink wig. I always thought it was a bit of a joke towards the paparazzi though. A sort of middle-finger up to them.
"Y'all follow me around all the time so I'll give you something to look at".
I'm just thankful she put the wig into storage and hopefully, we won't see a repeat performance.
Oh Dear! Perez Hilton
Internet bad-boy, Perez Hilton might be more known for bashing celebrities, but it's hard for him to say anything with this hair.
He's sported pink hair quite a few times, most recently when his new children's book The Boy With The Pink Hair was released (publicity stunt much?).
Publicity stunt or not, he should just stay away from the pink hair dye. It's a very hard colour to pull off for women, and even harder for men, especially if they have short hair like this.
That's Better! Rachel McAdams.
Regina George is flawless. Well, Rachel McAdems is flawless. I really do love this pink look. When pink is done right, it can really work.
Rachel has toyed with pink hair a few times, but this is my favourite look. Just a few pink flashes through the front of her ash blonde work so well, and it a look I am seeing a lot of blonde women going for.
It's only a small change to your hair, but a huge change to your look, and if you are thinking of going pink, but don't want to dive in head first (I really should stop with the bad jokes), then this is the perfect way to do it.
That's Better! Avril Lavigne
I'm not the biggest fan of Avril Lavigne. I never have been. Everyone seems to have gone through an Avril phase except for me. However, I don't mind admitting she pulls of the pink.
Over the years, pink and Avril have gone hand in hand, and it's a look she's always revisiting. She often goes for pink through the front of her hair, and even though the hot pink fringe is a bit dated and 'been there, done that', it is still working for her.
I don't know how she does it, but she forever looks like a teenager, and this hair is kind of keeping her there.
I think her pink 'dips' doesn't look too bad either.
That's Better! Nicki Minaj
Queen of the wigs (I'm sure that is a post all of its own), Nicki Minaj has sported many wigs over the last few years, and she often likes to don a pink one.
There has been so many pink Nicki moments, it's hard to pink one, but she always makes it work.
The pale pink she picks works with her skin tone and over the top make up, and it's a very cute look for Miss Minaj.
Then again, she was pretty much worn the entire rainbow on her head.
That's Better! Katy Perry
Even though I will always be a huge fan of Katy Perry's black hair, I think she pulls pink off rather well. When she first went pink, it was a nice, toned down shade (but then it kind of washed out and went a really horrible colour).
She sported pink hair a few times, before then going blue. Since getting rid of her black hair and chopping it all off, it is rather hard to keep up.
I always really do love her blonde/pink hair from a few months ago. It worked so well and made her so radiant. I'm sad we barely got to see it.
That's Better! P!nk
It's kind of in the name isn't it? P!nk. When pink first burst onto the scene all those years ago, she had very hot pink hair.
At the time, I was a fan of it, until she dyed it blonde (which I think she suits much better).
My favourite version of her pink hair though, is the strawberry blonde pale pink she rocked a few years ago.
It's very subtle, very under-stated, but very P!nk.
Even though P!nk didn't invent the colour, she brought it to the forefront of people's attention a lot, and it was a bit of a shock to the system.
So, what have we learnt here? Do pink right, and you might just get away with it, but proceed with caution, because it is a hard colour to correctly pull off.
