Wavy hair is a bit of a chameleon. Honestly, most people—including some of the biggest stars in Hollywood—spend years thinking their hair is just "frizzy" or "poofy" before realizing they actually have a distinct 2A or 2B wave pattern. It’s that middle-ground texture. Not quite curly, definitely not straight. It’s the texture that made the "beach wave" a multi-billion dollar industry, yet it’s surprisingly difficult to maintain without looking like you just rolled out of a haystack.
Actresses with wavy hair have basically become the blueprint for modern red carpet glamour. Think about the effortless, lived-in texture of stars like Alexa Chung or the classic, Old Hollywood undulations seen on Margot Robbie. These aren't just "born with it" moments; they are strategic masterclasses in moisture management and weight distribution. If you’ve ever tried to replicate a celebrity’s waves only to end up with limp strings or a triangle-shaped head, it’s probably because you’re treating your waves like curls. Or worse, like straight hair.
The Science of the S-Shape
What defines the hair of these actresses? It’s the "S" shape. Unlike curly hair, which spirals from the root, wavy hair usually stays relatively flat at the scalp and begins its bend a few inches down. This creates a specific set of problems. Because the hair is flatter at the top, natural oils from the scalp travel down the shaft more easily than they do with tight coils. This makes wavy hair prone to getting weighed down.
Julia Roberts is perhaps the most famous example of someone who transitioned through every possible iteration of the wave spectrum. In the late '80s and early '90s, her hair in Pretty Woman was a glorious, voluminous mass of red waves and curls. As she aged, and as styling trends shifted toward the sleekness of the early 2000s, we saw her texture change. But even now, when she leans into her natural state, you see that classic S-pattern that requires volume at the root to avoid looking "bottom-heavy."
Why Texture Is Often Misunderstood in Hollywood
For a long time, Hollywood stylists were obsessed with "taming" texture. They’d take someone like Sarah Jessica Parker—who has a mix of curls and waves—and blow it out within an inch of its life. It took a cultural shift toward "French Girl" hair and "Scandi-waves" for actresses to start embracing their natural bends.

Take Sophie Turner or Saoirse Ronan. Both frequently sport hair that looks like it was air-dried on a yacht in the Mediterranean. It’s intentional. They use what’s known as a "diffuser" or "plopping" technique, even if their stylists are the ones doing the heavy lifting. The goal is to keep the cuticle closed to prevent frizz while encouraging the wave to "clump" together. When waves don't clump, you get frizz. It's basically just a wave that lost its way.
The Anne Hathaway Evolution
Anne Hathaway is a great case study. If you look at her early Princess Diaries era, they leaned into the "frizzy" trope to signify her character was unkempt. They brushed out her waves. Never brush dry wavy hair. That’s the golden rule. Brushing breaks the S-pattern and creates a cloud of static.
In recent years, Hathaway’s red carpet looks have embraced a much more polished, heavy wave. Her hair has incredible density. For actresses with thick, wavy hair, the challenge is weight. If the hair is all one length, the weight of the hair pulls the waves straight at the top. This is why you’ll notice stars like Jennifer Aniston—who has a subtle natural wave—often use long, internal layers. These layers remove bulk and allow the hair to "bounce" up.
Key Products Used by the Pros
You won't find a celebrity stylist worth their salt using heavy, oil-based creams on wavy-haired actresses. It’s too much. Instead, they reach for foams and mousses.
- Volumizing Mousse: This provides the "grit" needed to hold the shape without the crunch of 90s hairspray.
- Sea Salt Sprays: Used sparingly, these mimic the effect of salt water, which dehydrates the hair just enough to make it "shrink" and wave more intensely.
- Lightweight Gels: Often referred to as "custards," these create a cast around the hair while it dries.
Zendaya is a master of the texture pivot. She can go from a 4C afro-textured look to a 2C beach wave seamlessly. When she wears her hair wavy, it’s clear that hydration is the priority. Wavy hair is naturally porous. It drinks up moisture, but if you give it too much, it loses its structural integrity.
The "Squish to Condish" Method
You might have heard of the Curly Girl Method (CGM). While it's a bit extreme for some, actresses with wavy hair often use a modified version. The "Squish to Condish" technique involves leaning over, filling your palms with water and a bit of leave-in conditioner, and squishing your hair upward toward the scalp.
This sound—the "squelch"—is the sound of the hair cuticle absorbing moisture. It forces the water and product into the hair shaft. For someone like Salma Hayek, whose waves are thick and prone to dryness, this kind of deep hydration is what gives the hair that reflective, mirror-like shine on camera. Without it, wavy hair looks matte. And matte hair looks damaged, even if it isn't.
Common Mistakes People Make with Wavy Hair
Honestly, the biggest mistake is over-processing. We see it all the time. Someone has beautiful, natural movement, and they hit it with a flat iron every single morning. Over time, heat damage kills the "memory" of the wave. The hair becomes "heat-trained" to stay straight, and when you try to wear it natural, it just looks limp and sad.
- Towel Rubbing: Don't do it. Use a microfiber towel or an old T-shirt.
- Too Much Silicone: Silicones make hair look shiny temporarily but can build up, making waves heavy and greasy.
- Ignoring the Scalp: Wavy hair needs a clean scalp. Because we use more styling products (mousse, gel, spray), buildup is inevitable.
Celebrities like Amanda Seyfried often have hair that looks "virgin"—meaning it doesn't look like it's been touched by chemicals. Her waves are soft and fluid. That’s the result of low-heat styling and probably a lot of silk pillowcases. Silk doesn't snag the hair cuticle like cotton does, which is vital for maintaining the integrity of a wave pattern overnight.
Shaping the Face
The way waves fall around the face can completely change someone’s bone structure. For actresses with heart-shaped faces, like Reese Witherspoon (who has a natural wave that she often blows straight), waves that start at the chin can help balance a pointed jawline. For square faces, soft waves help blur the sharp angles of the jaw.
It’s all about where the "bend" happens. Stylists will often use a curling wand to "reinforce" a few natural waves around the face, even if the rest of the hair is air-dried. They call it "the anchor." By defining the pieces that frame the eyes and cheekbones, the rest of the hair can stay messy and natural without looking unpolished.
The Reality of "Perfect" Celebrity Hair
We have to be real here: half the actresses with wavy hair you see on screen are wearing "fillers." No, not face fillers—hair fillers. These are individual extensions or wefts added specifically to give the waves more "girth." Wavy hair can sometimes look thin at the ends because the hair bunches together. Adding a few extensions provides that blunt, thick base that looks so good in photos.
Think of Chrissy Teigen. She’s very open about her use of extensions. Her natural wave is beautiful, but that "extra" factor comes from added density. If your hair feels "stringy" when you wear it wavy, it’s not because you’re doing it wrong; it’s just the physics of your hair density.
Actionable Steps for Managing Your Waves
If you're ready to embrace your inner Hollywood starlet and stop fighting your texture, you need a plan. It’s not about buying twenty products; it’s about the technique.
First, stop using a standard brush. Get a wide-tooth comb and only use it in the shower while you have conditioner in your hair. Once you rinse, your hair should not be touched by a comb or brush until the next wash. This preserves the "clumps" of hair that form waves.
Second, experiment with the "bowl method." You dunk your hair into a bowl of water mixed with a little leave-in conditioner, squishing as you go. It sounds messy because it is. But the results? Incredible. It’s how you get that saturated, frizz-free look that someone like Mila Kunis often sports.
Third, find your "hold" product. If your hair is fine, go for a foam. If it’s thick, try a light gel. Apply it to soaking wet hair. Yes, soaking. If your hair has already started to dry, you’ve already missed the window to prevent frizz.
Finally, let it be. Wavy hair is supposed to move. It’s supposed to be a little bit "undone." The more you touch it while it’s drying, the more you’ll mess it up. Once it’s 100% dry, you can "scrunch out the crunch" (SOTC) to break the gel cast and reveal soft, bouncy waves that actually last all day.
Wavy hair isn't a curse or a "transition phase" to curls. It’s a specific, beautiful texture that—when handled with a bit of science and the right tools—looks more expensive than any blowout ever could.
Next Steps for Your Hair Routine:
- Identify your porosity: Drop a clean strand of hair in a glass of water. If it sinks fast, you have high porosity and need more cream-based products. If it floats, you have low porosity and need lightweight, water-based formulas.
- Switch to a microfiber hair wrap: This reduces mechanical friction and speeds up drying time without disrupting the wave pattern.
- Clarify once a week: Use a chelating shampoo to remove the minerals and product buildup that inevitably weigh down wavy hair patterns.
