25% off Olaplex's popular hair masks on Black Friday

Taking care of your hair can feel like a full-time job. Just when you think your hair is finally in good condition after changing shampoos and applying plenty of conditioner, the weather changes and you have to start all over again. Luckily, the best hair masks can transform your hair overnight, and even luckier, the Black Friday sales will get you one of the best-rated hair masks ever for cheaper than ever.

Olaplex No 3 Hair Perfector (opens in new tab) is just what you need to repair and strengthen damaged, damaged, and aging hair, and Cult Beauty (opens in new tab) has it for $27.12, currently $36.16. Just add the code CBBF25 at checkout to enjoy 25% off for healthier hair.

Quickly, this mask is probably the best-kept secret in the hair care industry, and the proof is evident in the glowing reviews it has received on the Internet.

"After just one use, my hair went from so-so to fabulous, magical, super soft hair! Best investment I've ever made. You need it in your life!"

The nourishing mask can also count celebrity hair among its fan base; in 2018, Drew Barrymore posted a shot of her extremely dry and coarse hair on Instagram. She then elaborated on the trick behind her super smooth and shiny waves. Yes, it's Olaplex.

Kim Kardashian is also known to praise the product, revealing that she often puts it in her hair before bed as an overnight treatment. When it comes to hair, you can't get much more slippery than Kim, can you?

So what is this acclaimed treatment actually, a professional-level hair treatment specifically designed to strengthen hair by rebuilding keratin bonds (i.e., what it takes to have good hair for life), previously only available in salons. Thankfully, it is now available in convenient little bottles, so you can achieve the salon's finish in the shower at home.

This mask treatment boasts the active ingredient bisaminopropyl diglycol dimaleate, which repairs broken bonds responsible for hair elasticity, strength, and shine. Bleaching, coloring, daily pollution and chemicals can destroy these bonds, but Olaplex repairs them.

In short, if used as a pre-shampoo treatment (and left on for as long as possible), the genie in this bottle will change your hair forever. I suggest you head over to check it out ASAP.
