If you’ve been on the hunt for a product that gives you smooth, shiny, and defined curls without weighing them down, look no further. Our new Shine & Define Serum was made just for curls and we’ll show you exactly how to use it to get the most out of every drop.

Whether you're dealing with humidity, flyaways, or lack of definition, knowing how to use a curly hair serum properly can make all the difference in your styling routine.

Why Use a Hair Serum on Curls?

Curly hair needs a delicate balance of moisture, definition, and protection. Traditional serums often contain heavy silicones that coat the hair leading to build-up, and this blocks out the moisture needed for curls to thrive.

Our anti-frizz Shine & Define Serum is different. It's a lightweight, silicone-free serum made with innovative curl-friendly ingredients that smooth frizz, tame flyaways, and enhance shine — all without build-up or greasiness.

When Should You Use the Shine & Define Serum?

The serum is designed as a finishing product for the ultimate frizz control. That means it works best when used on dry curls to:

  • Add shine
  • Reduce frizz
  • Tame flyaways
  • Lock in curl definition

It’s perfect for post-wash day styling, refreshing second- or third-day curls, or finishing off your look before heading out.

How To Use the Shine & Define Serum

Here are our go-to curl styling tips for getting the most out of your Shine & Define Serum:

  1. Start small - A little goes a long way. Start with 1-2 drops and rub between your palms to evenly distribute.
  2. Apply to dry hair - Glide your hands gently over your curls to smooth any frizz or flyaways. Focus on the mid-lengths and ends, where hair tends to get the most dry and dull.
  3. Scrunch it in - For added definition, scrunch the serum into your curls to enhance bounce and shape.
  4. Use between wash days - Add a drop to refresh and revive dull, frizzy curls between washes. It brings life and shine back to your style in seconds.
  5. Layer products wisely - If you use our Curl Creme and Gel, apply the Shine & Define Serum after these products, once your hair is fully dry. It’s the final glossy step.

Pro-tip for the Ultimate Frizz Control

Humidity got your curls puffing up? Use a tiny bit of the Shine & Define Serum on your fingertips to spot-treat areas around your hairline or parting where frizz loves to show up. It's an instant smooth-down without any crunch.

Knowing how to use the Shine & Define Serum for frizz-free, glossy curls can totally elevate your curl routine. It’s the ultimate finishing touch — lightweight, non-sticky, and packed with clean, curl-loving ingredients.

So whether you're heading out the door or reviving your curls mid-week, the Shine & Define Serum has your back. Because glossy, defined, frizz-free curls? They’re always in style! Try the Shine & Define Serum on your next wash day to see the difference in your curls.
