How to Break a Gel Cast (and Get Big, Full, Frizz-Free Curls)

If you’re using gel in your curly routine—and we hope you are—chances are you’ve encountered a gel cast. That stiff, crunchy layer that forms as your gel dries? That’s the cast. And while it might not feel great at first touch, it’s actually a very good sign.

A gel cast forms when your curl gel sets around each strand to lock in definition and hold. It protects your curls during drying, minimizes frizz, and helps curls keep their shape longer. But the key to soft, bouncy, voluminous results? Knowing how to break the gel cast the right way.

Because once you break the cast, that’s when the real magic happens—curls open up, volume comes to life, and your definition stays intact.

Let’s break it all down: what a gel cast is, why it’s essential, and how to soften it for the best results possible.

What is a gel cast, exactly?

A gel cast is the firm shell that forms around your curls when a styling gel dries on the surface of the hair. It's not a bad thing—in fact, it’s a curl-defining MVP. That crunch is temporary and intentional. It creates a barrier that keeps humidity, friction, and frizz out while your curls set in place.

When broken properly, the cast reveals soft, shiny, frizz-free curls with long-lasting hold.

Why breaking the cast matters

If you leave a gel cast untouched, you’ll keep the hold, but miss out on the softness, bounce, and volume. On the flip side, if you break it too early or too aggressively, you might create frizz or lose definition.

The goal is to break the cast strategically, with the right method and the right product, so you keep all the curl-enhancing benefits and none of the crunch.

How to break a gel cast (without frizzing out your curls)

Here’s a step-by-step guide to softening your gel cast and unlocking volume and movement in your finished style.

Step 1: Make sure your hair is 100% dry

This is non-negotiable. If your hair is even slightly damp, breaking the cast too early can lead to frizz or disrupt your curl pattern. Whether you air-dried or diffused, do a quick check—if your roots feel cool, give it more time.

Step 2: Choose the right oil or serum

The best oil to break gel cast adds slip and shine without weighing curls down. You want something lightweight, non-greasy, and curl-friendly.

We recommend:
Unbreakable Bonds™ Weightless Bonding Oil – This fast-absorbing bonding oil strengthens hair from within while giving you that silky glide needed to break the cast gently. It’s one of our favorites for finishing styles and refreshing curls throughout the week.

Mongongo Oil Multi-Use Curl Treatment – Great for dry or high-porosity curls, this oil provides a nutrient-rich layer of moisture and makes breaking the cast easier and smoother.

Dispense a small amount (1–2 drops) into your palms, rub your hands together to emulsify, and proceed to the next step.

Step 3: Scrunch out the crunch

Use your hands to gently scrunch your curls upwards—starting from the ends and moving toward the roots. Think of it as “re-activating” your natural bounce. Use open hands and squeeze lightly without pulling.

Focus on sections with the most visible cast. As you scrunch, the stiffness will give way to softness, and your curls will spring into life.

Pro tip: Flip your head upside down while scrunching to encourage root lift and volume.

Step 4: Fluff the roots for volume (optional)

If you're going for big, full curls, now’s the time to boost your roots. Use your fingers or a pick to gently lift at the scalp. Don’t rake through the hair—just shake and lift from the base to add height.

Still want more? Try diffusing again on low heat for 2–3 minutes with your head flipped to reactivate volume. This works especially well on finer curls that need a little extra boost post-drying.

Step 5: Finish with a refresher spray (if needed)

If your curls feel a little too soft or you’re refreshing second-day hair, follow up with a light mist of curl refresher to revive definition and fight frizz.

Try: Botanical Boost® Curl Energizing & Refreshing Spray – A lightweight, hydrating spray that helps reawaken curls and revive bounce without buildup. It’s especially great after oil application to seal moisture and enhance movement.

How to get big full curls with the gel cast method

Breaking a gel cast is more than a technique, it’s a styling strategy. Done well, it helps you get long-lasting curl definition and volume. Here’s how to turn it up:

Step 1: Start with the right gel

Use a product that forms a strong but flexible cast. Advanced Climate Control® Heat & Humidity Gel – Original Hold is our go-to. It protects curls from humidity and frizz, locks in curl shape, and sets the perfect base for volume after breaking the cast.

Step 2: Apply gel on soaking wet hair

This helps the gel coat your curls evenly and encourages clumping and definition. Scrunch or use the “praying hands” method for smooth, sealed-in strands.

Step 3: Diffuse upside down

Drying with your head flipped over adds root lift and helps create more fullness once the cast is broken.

Step 4: Pick or fluff the roots

After scrunching out the cast, gently lift the roots with your hands or a wide-tooth comb to add extra height. Don’t go overboard—just enough to boost volume without disrupting the curl pattern.

What to avoid when breaking the cast

• Breaking it too soon: Always wait until your hair is completely dry

• Using too much oil: A few drops are enough. Too much can weigh curls down

• Over-scrunching: If you scrunch too aggressively or for too long, you risk frizz

• Skipping the seal: A curl refresher or lightweight spray helps lock in the softness and definition after breaking the cast

Crunchy now, soft later

The gel cast might not feel cute while it’s forming, but trust us, it’s doing the work. It’s keeping your curls in place, locking in the shape, and creating that defined, long-lasting hold we all want. Breaking the cast the right way transforms that crunchy finish into soft, bouncy, big full curls that last for days.

Whether you’re a cast-breaker pro or new to the method, a few strategic moves—and the right products—make all the difference.
