We've got the secret to Blake Lively's gorgeous highlights

By: The Beauty Experts at L'Oréal Paris

It's a pretty good bet that if you're scouring the web for celebrity hair color inspiration, Blake Lively's picture will pop up. And for good reason, too. Blake's blond tresses have the perfect balance of tones -- in other words, seamlessly blended, über-luminous highlights. And, even better, we've got the secret to how you can get them.

Our latest discovery (and obsession) -- L'Oréal Paris Glam Lights -- is the key. This highlighting kit is a total game changer. It's so easy to use, and the results? Well, they're basically red-carpet-worthy. Keep reading -- you'll see what we mean.

Why We Love It:
When it comes to DIY highlighting kits, you've got a few things to consider: the formula, the technique and the application tool. Glam Lights takes the guesswork out of all three. The formula comes in three shades (GL90, GL70 and GL50), so even if your hair is more of a medium brown, you can get your glow on. The technique mimics brushing your hair (so you've probably already mastered it). And the tool (or, the main reason we're completely enamored) is so unique and innovative that even a first-time DIYer will feel like a pro.

In the past, women had to rely on a cap-and-hook technique to create at-home highlights. The process was lengthy, and the results: chunky streaks. More recently, we've resorted to stocking up on toothbrushes to precisely place color on each strand. And even an expert will tell you that a toothbrush was never meant for coloring an entire head of hair. But the Glam Lights Highlights Brush -- a three-prong brush that applies three highlights at the same time -- eliminates the need for any other applicators.

How It Works:
The bristles of the three channels are a combination of short and long lengths and were designed to help create a beautiful blended highlight result. The channels of the brush serve as a guide to help you determine how much formula to place on the brush. Once you've got the formula on the brush, it's really as simple as brushing your hair, though we did find that by following the directions here and using the below tips, we got the best results:
  1. Start in the back and pin up your hair to best reach those hard-to-hit strands.
  2. Refill the Expert Highlights Brush in between strokes.
  3. Hold the brush vertically during application!
  4. Apply with light pressure at the roots and put extra pressure on your ends.
  5. Rinse with the Preference Luminous Conditioning Shampoo.

What's Next:
Now that you've got the luminous highlights, you'll want to make sure you're doing everything possible to keep them glowy. A shampoo-and-conditioner combo made just for color-treated hair is the way to go. Our pick, EverPure, doesn't have harsh salts and parabens, and helps keep your color pure longer.
