Ever looked in the mirror after a shower and wondered why one side of your head looks like a Shirley Temple ad while the back is just... fuzzy? You aren't alone. Most people obsess over finding their "number" on a chart, thinking that knowing they are a 3C or a 4A is the magic key to perfect hair. It isn't.
Hair typing is basically a shorthand. It’s a way to talk about the shape of your strands, but honestly, it’s only about twenty percent of the puzzle. The industry largely follows the system created by Andre Walker—Oprah’s long-time stylist—back in the 90s. It was revolutionary at the time because it actually gave people with textured hair a vocabulary. Before that, you just had "frizzy" or "unmanageable." Now, we have a scale from 1 to 4. But here’s the kicker: your head probably hosts three different curl patterns at the same time.
The Breakdown of the 1 to 4 System
Type 1 is straight. We aren't here for that. Type 2 is wavy. This is where the hair has a definite S-shape but lays closer to the head. If you’ve got 2A hair, it’s fine and thin, almost straight but with a slight tousle. 2C is where it gets tricky. These are thick, coarse waves that are often mistaken for curls but lack that full 360-degree spiral.
Then we hit Type 3. This is "true" curly hair. Think of a corkscrew. If you took a single strand and wrapped it around a Sharpie, that’s roughly the diameter of a 3A curl. As you move to 3B and 3C, the circumference gets smaller—think of a highlighter or even a standard pencil. 3C hair is often called "curly-coily" because the density is high, and the curls are packed tight.

Type 4 is coily or kinky. This is the most fragile hair type. Period. 4A curls have a visible S-pattern and are about the size of a crochet needle. 4B? That’s where the "Z" shape comes in. Instead of curling, the hair bends at sharp angles. 4C is the tightest of them all. It’s densely packed, prone to massive shrinkage—sometimes up to 75% of its length—and has the most delicate cuticle layer.
The Lie of the "Uniform" Head
You probably don't have just one pattern. It’s a myth. Most humans have a mix. You might have 3C curls at the nape of your neck where it's protected and moist, but 4A at the crown because of sun exposure or how you sleep.
Treating your whole head like a monolith is why your products "stop working." If you apply a heavy shea butter meant for 4C coils to your 3B sections, those curls are going to go limp. They’ll look greasy. Conversely, if you use a lightweight mousse meant for Type 2 waves on Type 4 coils, you're going to end up with a cloud of untamed frizz by noon. It's about mapping. You have to learn where your different curl patterns live.
Why Your Pattern Matters Less Than You Think
I’m going to be real with you: Porosity is more important than your curl shape.
Porosity is your hair’s ability to absorb and retain moisture. You can have 4C hair that is "low porosity," meaning the cuticle scales are closed tight like shingles on a roof. Water literally bounces off it. Or you could have 3A curls that are "high porosity" because of bleach damage, meaning the hair drinks up water but loses it just as fast.
- Low Porosity: Needs heat to open the cuticle. Think steamers or warm towels.
- High Porosity: Needs sealants. Heavier oils and cold-water rinses to "lock" the door.
If you only shop by your curl number, you are ignoring the biology of the strand. A 4C person with high porosity and a 3A person with high porosity actually have more in common regarding their product needs than two people who both happen to have 3B curls but different porosity levels.

The Role of Elasticity and Density
Elasticity is the "snap-back" factor. Healthy hair should stretch and return to its original shape without snapping. If your curls are limp and don't hold their shape, you likely have a protein-moisture imbalance. Too much conditioner makes hair "mushy." Too much protein makes it brittle like dry hay.
Density is another beast. This is simply how many hairs are on your head. You can have very tight, 4C coils but "low density," meaning your scalp is easily visible. Or you can have 2A waves with "high density," giving you a massive mane that takes six hours to dry. This changes how you apply product. High density needs sectioning. Low density needs "praying hands" application to avoid weighing things down.
Stop Chasing the "Crunch"
One of the biggest mistakes in managing various curl patterns is the fear of the crunch. We’ve been told for decades that crunchy hair is bad. But for Types 2 and 3, that "cast" created by gel is what preserves the pattern. If you scrunch out the crunch (SOTC) before the hair is 100% dry, you break the seal. You invite frizz.
For Type 4 hair, the goal is usually different. It’s about elongation and lubrication. Because the "Z" or "S" turns are so sharp, the natural oils from your scalp (sebum) can’t make it down the hair shaft. This is why coily hair feels dry. It’s not that it is inherently dead or damaged; it’s just that the "road" the oil has to travel is full of hairpin turns.
Real Talk on Damage
Heat damage is the great equalizer. It kills all curl patterns equally. Once you've fried the disulfide bonds in your hair with a 450-degree flat iron, your 3C curls will look like 2A waves, but with the texture of sandpaper. There is no product that "fixes" this. Bonds can be temporarily patched with things like Olaplex or K18, but the only real cure for heat-damaged patterns is the "Big Chop" or a very long transition period.
Chemical damage from bleach does something similar. It blows the cuticle open. This is why many "blonde" curly girls find their curls won't "clump" anymore. Clumping is when multiple strands of hair move together to form a single, defined curl. When the cuticle is shredded, the strands snag on each other instead of sliding into a neat spiral.

Practical Steps for Your Routine
Stop washing your hair every day. Just stop. Textured hair needs that sebum. If you're a Type 4, you might only wash once every week or two. If you're a Type 2, maybe every two or three days.
1. The Squish to Condish Method
When you’re in the shower, don’t just rinse your conditioner out. Flip your head over. Cup water in your hands and "squish" it into your hair along with the conditioner. You should hear a squelching sound. This forces moisture into the hair shaft rather than just letting it sit on top.
2. Microfiber Only
Throw away your terry cloth towels. The tiny loops on a regular towel act like Velcro on your hair cuticles. They rip them open and cause frizz before you’ve even stepped out of the bathroom. Use an old cotton T-shirt or a microfiber towel. Blot, don't rub.
3. The LOC/LCO Method
This is the gold standard for Type 3 and 4 hair.
- Liquid (or leave-in conditioner)
- Oil
- Cream
The order depends on your porosity. If you’re high porosity, go LOC. If you’re low porosity, LCO usually works better because the cream can penetrate before the oil seals everything off.
Identifying Your Unique Mix
Go look at your hair while it's soaking wet. That is your truest pattern. As it dries, gravity and evaporation take over. If your hair looks curly when wet but straight when dry, you have a moisture retention issue, not a "lack of curls."
If you see "webbing"—where the hair looks like a spider web between the curls—you need more hold. You need a gel with a stronger polymer. If your hair feels "coated" or waxy, you have product buildup. Use a clarifying shampoo with sulfates once a month. Yes, sulfates. The "no-sulfate" movement went a bit too far; sometimes you need a heavy-duty detergent to strip away the silicones and butters that co-washes leave behind.
Your Curl Journey Isn't a Destination
It changes. Hormones, pregnancy, aging, and even the mineral content of your tap water will shift your curl patterns over time. Hard water is a silent killer for curls; it leaves calcium deposits that make hair feel stiff and straw-like. If you live in a hard water area, a shower filter is more important than any $50 hair mask.
Focus on health first. A healthy 2B wave looks better than a damaged, struggling 4A coil. Don't fight the shape your DNA gave you. Learn the "map" of your head, identify which sections need more moisture and which need more protein, and stop comparing your "Day 1" to someone else’s "Year 5" on Instagram.
Start by auditing your current shelf. Look for silicones that aren't water-soluble (like Dimethicone) if you struggle with limp hair. Switch to a silk or satin pillowcase tonight to prevent mechanical breakage while you sleep. Most importantly, give your hair a "reset" wash with a clarifying shampoo to see what your natural texture actually looks like without months of product buildup masking it. Once you see the raw pattern, you can finally start building a routine that actually works.
