Lily James isn’t just playing Pamela Anderson on the screen, she’s also clearly taking inspiration from the legendary star in real life. Namely, James just went blonde, and her stylist John MacPherson was the first to debut the pics. IRL, we’ve long known James as a brunette, but her new buttery blonde shade is insanely flattering. Not only is the color phenomenal, but it also looks insanely healthy—which isn’t an easy feat when you’re playing with bleach.

Going from dark brunette to blonde can be quite an endeavor—and it can also be really tough on hair. Bleaching damages the bonds in your hair, which can leave it brittle, dry, and mangled with split ends. It’s important to try and tackle that damage before it even starts if you’re considering going lighter, which is why MacPherson turned to a product that’s already gone viral on TikTok: K18’s Leave-In Molecular Repair Hair Mask.

The K18 Leave-In Molecular Repair Hair Mask is basically a hair mask that you don’t wash off, and it’s clinically proven to start reducing hair damage in just 4 minutes. It’s ideal for someone like James who just bleached their hair, but it’s also a miracle-worker for anyone who has damage from chemical services or heat. 

As someone who colors their hair regularly and uses a fair amount of heat, I can personally attest that K18 helps make my hair feel stronger, softer, and shinier after just one use—it’s been a major staple in my haircare routine since it launched, and it’s one of those rare products that I will actually spend money on. It’s well-worth every penny, particularly if you feel like your hair needs major reviving.

When it comes to bond-building hair treatments, Olaplex has basically cornered the market. These two products work in tandem with each other as one treatment to help repair hair and reverse damage. Saturate hair with No. 0 and let it sit for 10 minutes before following up with No. 3 and letting it sit for another 10 minutes before you get in the shower. 

This is one of my personal favorite treatments for hair, because it’s so easy to use. It’s clinically proven to help reduce damage. Smooth it on after you condition your hair, and either rinse it off or let it sit in your hair as a leave-in conditioner for maximum results. 

Multi-tasking products are always the best way to go, and this treatment both helps repair hair and works as a heat protectant up to 450 degrees. 

Bond-building technology and wildflower honey work together to strengthen hair and improve elasticity in this once a week, in-shower treatment. It also helps detangle and prep your hair for styling, making the rest of your routine easy.

K18’s new shampoos work to nourish hair with the same peptide complex used in their leave-in mask.
