What Is Overnight Serum + 5 Picks To Try Now

We all want to wake up with Instagram-worthy hair. The problem is, if you’re dealing with some serious hair woes, your daytime hair serums and leave-in treatments just might not cut it—not to mention the fact that adding a product or two to your daytime routine can add time to your already jam-packed schedule. The good news? Overnight hair serums are on the rise, and they’re specifically formulated to beautify your strands while you sleep. 

Looking to learn more about overnight serums? We tapped Erika Dawn Shear, Shu Uemura Art of Hair artist and brand ambassador, to find out what exactly overnight serums are. Plus, we break down our top picks for you to try the next time you catch some Z’s. Whether you have dark brown hair or ash blonde strands, keep scrolling for everything you need to know. 

What is overnight serum? 

Let’s face it: We can use all the help we can get during the only uninterrupted hours of our days. That’s where overnight serums come in. While standard hair serums are meant to protect hair from exposure to the sun and environmental factors during the day, overnight serum is a cream or oil applied to the hair before bed that works to repair your strands while you sleep.

“During the day, our hair is exposed to different free radicals that can cause damage. Daytime serums are great to minimize any damage caused by these aggressors. At night, our bodies naturally switch to repair at a cellular level,” Shear explains. “This eight hours of sleep gives our hair a break from heat, styling, and day-to-day health risks—the optimum time to use a reparative night serum!” 

Who is overnight serum best for?

Whether you have fine hair that lacks volume or soft waves in need of definition, every hair type has its own needs. Luckily, an overnight serum can be a total game-changer for repairing your hair regardless of type or texture. If your strands need an extra dose of nourishment, an overnight serum may  be the Holy Grail product you’ve been looking for.
