Purely Platinum Parade Of Celebs Just In Time For NY Fashion Week!

When we think platinum, we think of something very expensive, or movie icon Marilyn Monroe and of course, our generation's uber blonde girl--Gwen Stefani.

And now heading into NY Fashion Week, the buzz appears to be on PLATINUM hair, because celebrities are taking the platinum plunge. And it's a sexy, cool, classic look.

Over time, purely platinum does a number of bad things to your locks. Your mane can end up resembling straw, appear extremely frazzled , take on a brassy shine or even worse, fall out.

But when the platinum is done by a professional, well-cared for, it's hard to ignore the rich high-wattage hair color. Platinum gets a lot of attention.

Gwen is the most, well-maintained platinum blonde beauty we have EVER seen, because she will NOT venture out in public if those tell-tale dark roots are showing. So the star is very religious about her strict platinum routine.

This is what Gwen revealed to Harper's Bazaar 2 years ago about maintaining platinum locks:

"Do you think Marilyn Monroe had to talk about this?" she asks smiling. "Well, I heard she did hers with a Q-tip every 10 days, so I try to follow Marilyn's rule." I mention that she's never been photographed with dark roots..... "And you'll never see me with roots either."

About discovering the beauty of bleach, Gwen says it changed her life big time!:

Gwen recalls how she felt when, at the age of 25, she spent 8 hours in a hair salon in Long Beach getting her coveted white-blonde locks. "It was like I'd unlocked the key. I remember feeling like, 'I have arrived. This is me. Finally.'" 

We LOVE platinum hair. However, our mane is as dark as a Kardashian, so----we can't go there without some major hair damage.

But for those of you who can and will go PLATINUM, lucky you! But don't forget to CONDITION!

Celeb stylst Mara Roszak suggests this one by L'Oreal ($9.29, at CVS). She even uses it herself:

“For hair there’s nothing like L’Oréal Paris OleoTherapy Sulfate-Free Deep Recovery Mask for a weekly treatment. The number one concern women have with their hair is dryness, which not only doesn’t look great, but makes hair almost impossible to style. This mask will save your hair! I use it at least once a week and apply a shower cap while in the shower, allowing it to penetrate deeper from the steam for at least five minutes.”
