Curly hair is a liar. One day you wake up with perfect, springy coils that look like they belong in a shampoo commercial, and the next, you look like you’ve been electrocuted in a wind tunnel. It’s frustrating. Most people walking around with a "frizz problem" actually just have a "misunderstood curl pattern" problem. Honestly, if you don't know the specific kinds of curly hair growing out of your own scalp, you're basically throwing money away on expensive jars of goo that might be doing more harm than good.
I’ve spent years obsessing over the Andre Walker Hair Typing System—the industry standard created by Oprah’s longtime stylist—and while it’s a great starting point, it’s not the whole story. Your head is a map. Usually, you don't just have one hair type; you have a chaotic neighborhood of different textures. You might be a 3A at the nape of your neck and a 2C at the crown. Understanding these nuances is the difference between a good hair day and a hat day.
Breaking Down the Kinds of Curly Hair Without the Fluff
We need to talk about the numbers and letters because that’s how the world organizes this stuff. Type 1 is straight, so we’re ignoring that. We start at Type 2.
Type 2 is Wavy. This isn't just "messy straight hair." It has a distinct S-shape. 2A is that fine, barely-there tousled look that many people mistake for just being "frizzy." It’s easily weighed down. If you put a heavy shea butter on 2A hair, it’s going to look greasy and flat by noon. 2B is a bit more defined, with the wave starting closer to the midpoint of the hair shaft. Then there’s 2C. Honestly, 2C is the most misunderstood of all the kinds of curly hair. It’s thick, prone to extreme frizz, and features a very tight S-pattern that almost looks like a curl but doesn't quite form a ringlet.
Type 3 is Curly.
Now we’re getting into actual spirals. 3A curls are large and loopy—think the diameter of a piece of sidewalk chalk. They have a lot of shine but lose definition the moment you touch them. 3B is tighter, more like the size of a Sharpie marker. These curls have more volume and a lot more attitude. Finally, 3C is often called "curly-coily." These are tight corkscrews, about the width of a pencil. This is where moisture becomes a life-or-death situation for your style.
Type 4 is Coily/Kinky.
This is the most fragile texture. Period. 4A hair has a visible S-pattern but it’s packed into tight, dense coils. 4B is different; it follows a Z-pattern. Instead of curving, the hair bends in sharp angles. 4C is the tightest of all, often with no discernible pattern unless it’s soaking wet and drenched in product. It experiences the most "shrinkage"—meaning your hair might be ten inches long, but it looks like two.

Porosity is the Secret Boss
You can know your curl type and still fail at styling. Why? Because of porosity.
This is basically your hair’s ability to soak up and hold onto water. If you have high porosity hair, your hair cuticles are wide open. It drinks water like a sponge but loses it just as fast. You’ll be dry again in twenty minutes. Low porosity hair is the opposite. The cuticles are closed tight like shingles on a roof. Water just beads up and rolls off. If you’re trying to moisturize low porosity hair with cold water and heavy oils, you’re just coating the outside. It never actually gets inside the strand.
To test this, take a clean strand of hair and drop it in a glass of water. If it sinks fast, you’re high porosity. If it floats for a long time? Low porosity. This matters more than your curl number. Truly.
Why Your "Routine" Probably Sucks
Stop scrubbing your hair with a towel. Just stop.
When you look at the various kinds of curly hair under a microscope, you see that the cuticle (the outer layer) is raised at the points where the hair bends or twists. This makes curly hair naturally more "snaggy" than straight hair. When you rub it with a rough terry cloth towel, you’re essentially velcroing your hair to itself and ripping the cuticle apart. That’s where the frizz comes from. Use an old cotton T-shirt or a microfiber towel.

Also, the "scrunch" is an art form. You can't just mash your hair. You have to gently cup the curls and move them toward the scalp. If you hear a "squelch" sound, you’re doing it right. That sound is water and product being forced into the hair shaft. No squelch, no definition.
The Misconception of "Heavy" Products
There is a massive myth in the curly community that "coarse" hair needs heavy oils. Actually, "coarse" refers to the thickness of the individual strand, not how it feels. You can have fine hair (thin strands) that is very curly. If you put heavy Jamaican Black Castor Oil on fine 3A curls, they will collapse. They’ll look limp and stringy.
Conversely, if you have 4C hair that is high density (a lot of hairs per square inch), you need those heavy hitters. You need the butters and the thick creams to provide enough weight to manage the volume and lock in that fleeting moisture.
The Science of the "C" and "S" Shapes
Ever wonder why your hair is actually curly? It’s not just magic. It’s the shape of your follicle. Straight hair grows out of a perfectly round follicle. Curly hair grows out of an asymmetrical, oval, or flat follicle. The flatter the follicle, the tighter the curl.
This is also why curly hair is almost always drier than straight hair. Scalp oils (sebum) have a hard time traveling down a spiral staircase. On straight hair, it’s a straight slide down to the tips. On a 4C coil, that oil gets stuck at the first three turns. You have to manually intervene by adding oils to the ends, or you’re going to deal with constant breakage.

Real Expert Advice: The "Bowl Method"
If you're struggling with definition, try the bowl method. It's a game changer for almost all kinds of curly hair, especially types 2 and 3. You apply your leave-in conditioner, then dunk your head into a bowl of water, catch the water that drips out, and pour it back over your head while scrunching. This forces the product and water to emulsify together. It creates "clumps." Clumps are the holy grail. Without clumping, your curls just separate into individual strands of frizz.
How to Actually Buy Products Now
Don't buy based on the "For Curly Hair" label. It's too broad. Look at the ingredients.
- For Type 2 (Wavy): Look for "weightless," "volumizing," or "foam." Avoid anything where the first three ingredients include shea butter or coconut oil.
- For Type 3 (Curly): Look for "custard," "jelly," and "milk." You need a balance of moisture and hold. Glycerin is great unless it’s a super humid day, then it’ll make your hair explode into a halo of frizz.
- For Type 4 (Coily): Look for "pudding," "butter," and "heavy cream." You need emollients. You need things that feel thick between your fingers.
The Role of Protein
Your hair is made of keratin. Sometimes, we over-moisturize. This leads to "hygral fatigue," where the hair becomes mushy and won't hold a curl. If your curls feel limp and "gummy" when wet, you need protein. Look for hydrolyzed silk, wheat, or soy protein in your masks. If your hair feels like straw and snaps easily, stop the protein and go back to deep conditioners. It’s a seesaw. You’re always trying to balance the two.
Practical Steps for Your Next Wash Day
Forget everything you think you know about "shampooing." Most people with textured hair shouldn't be "washing" their hair—they should be "cleansing" it.
- Step 1: The Pre-Poo. Apply an oil (like jojoba or coconut) to your dry hair 20 minutes before you get in the shower. This prevents the water from "shocking" your hair and causing it to swell too fast.
- Step 2: Sulfate-Free Cleansing. Sulfates are the same stuff in dish soap. They strip every bit of oil. Unless you have massive product buildup, stick to co-washes (conditioning washes) or sulfate-free shampoos. Focus only on the scalp.
- Step 3: The Squish to Condish. Apply a massive amount of conditioner. Comb it through with your fingers or a wide-tooth comb. Then, while your hair is soaking wet, start scrunching in water.
- Step 4: Style on Sopping Wet Hair. Do not dry your hair first. Apply your gel or cream while you’re still in the shower. The water helps distribute the product evenly across the different kinds of curly hair on your head.
- Step 5: Plop. Wrap your hair in that cotton T-shirt for 15 minutes to soak up excess water without disturbing the curl pattern.
- Step 6: Diffuse or Air Dry. If you use a hair dryer, use the diffuser attachment on low heat. Don't touch the hair until it is 100% dry. If you touch it while it’s 90% dry, you will create frizz.
Once it’s dry, your hair might feel "crunchy." This is the "gel cast." Don't panic. Just take a tiny drop of oil on your hands and "scrunch out the crunch." You’ll be left with soft, bouncy curls that actually stay put for more than an hour.
Managing your hair isn't about "taming" it. It’s about listening to what the specific fibers need. If your hair is thirsty, feed it water. If it’s weak, give it protein. If it’s wild, give it hold. Once you stop fighting the natural shape of your follicles, everything gets a lot easier.
Invest in a silk or satin pillowcase immediately. Cotton acts like a vacuum for moisture and a sandpaper for your cuticles while you sleep. Switching to silk is the single easiest thing you can do to preserve your curls for "day two" and "day three" hair. Protect the work you did in the shower. Keep your curls grouped together and stop the friction.
