Highlights of the blog: 

• Understanding your curl type helps you solve curly hair problems like frizz, flatness, and breakage more effectively
  

• Each curl pattern (2A to 4A) has specific needs — from lightweight hydration to deep moisture and detangling care
  

• The right products + routine = less guesswork, more good hair days

If you've ever looked in the mirror and thought, "Why won’t my curls behave today?" — you’re not alone. For many of us with textured hair, it starts with a question no one taught us how to answer: What’s my curl type?

Understanding your curl pattern is the first step to solving the most frustrating curly hair problems. Because what works for a 2A wave might totally fail on a 4A coil.

In this guide, we’ll walk you through four common curl types — 2A, 2C, 3A, and 4A — and break down the unique curly hair issues that come with each. You'll also learn how to choose the right products and routine so your curls can finally live their best life.

What is curl typing — and why does it matter?

Curl typing is a system used to classify textured hair into different categories based on how it bends, spirals, or coils. The numbers (2, 3, 4) refer to the broad category - wavy, curly, coily, while the letters (A, B, C) refer to how loose or tight the pattern is.

Knowing your type helps you:

• Choose the right level of moisture and hold
  
• Avoid the wrong techniques and products
  
• Understand the root cause of specific curly hair problems

Let’s break it down.

Type 2A: Loose waves that fall flat easily

What it looks like: 

2A hair has a gentle S-shape with minimal volume or body. It’s the loosest curl pattern - almost straight, but not quite.

Common curly hair problems:

• Limp roots and lack of volume
  
• Oily scalp but dry ends
  
• Frizz without defined waves

How to care for 2A curls:

The biggest mistake with 2A hair is overloading it with heavy creams. Stick to light, hydrating formulas like the XO Curls Leave-In Conditioner, which adds moisture without weighing down your waves. A soft-hold gel helps with subtle definition and frizz control.

Type 2C: Defined waves with a touch of curl

What it looks like:

2C hair has thicker, more defined waves, and may include some loose spirals. It’s more prone to puffiness and frizz than 2A or 2B.

Curly hair issues:

• Frizz and halo fuzz, especially in humidity
  
• Tangles and dryness at the ends
  
• Inconsistent curl pattern (some areas wavier than others)

How to care for 2C curls:

A balance of moisture and hold is key. Use a sulphate-free shampoo to prevent over-drying, and style with a leave-in + gel combo to enhance definition. XO Curls’ All Day Definition Gel is ideal — it offers flexible hold without crunch or buildup.

Type 3A: Soft spirals that crave balance

What it looks like:

3A curls are loopy, springy, and usually about the width of sidewalk chalk. They tend to have more volume and bounce than 2-type waves, but they’re still soft and silky.

Most common curly hair problems:

• Loss of curl definition after wash day
  
• Frizz from over-manipulation
  
• Product buildup weighing curls down

How to care for 3A curls:

Hydration is still important, but overdoing it can lead to limp curls. Alternate between co-washing and gentle shampooing, and never skip your conditioner. Our Hydrating Shampoo and Leave-In Conditioner duo gives 3A curls the right balance of clean + moisture + bounce.

Pro tip: Don’t touch your curls while drying! It’s one of the biggest triggers for frizz and loss of curl pattern.

Type 4A: Tight coils with serious shrinkage

What it looks like:

4A curls are dense, springy coils with lots of volume and shrinkage. They tend to have an “O” shape and are naturally drier due to fewer natural oils reaching the ends.

Curly hair problems to watch out for:

• Dryness and breakage
  
• Shrinkage that hides length
  
• Difficulty detangling without damage

How to care for 4A curls:

Moisture is your best friend. Incorporate deep conditioning weekly with tools like our Heat Cap, and always detangle in the shower with a wide-tooth shower comb — like our patented XO Curls Detangling Comb made for thick textures.

Seal moisture with an oil or lightweight gel. You need definition and hydration — not stiffness.

But wait! What if your curls don’t fit one category?

That’s totally normal. Most people have a mix of curl types - 2C at the front, 3A underneath, or 4A mixed with 3C at the crown. Curl typing is a guide, not a rulebook. The key is observing how your curls behave and respond to moisture, hold, and care.

Tip: Keep a curl journal for a week. Note how your hair looks and feels on wash day, day 2, and day 3. This will help you spot patterns and figure out what your hair really needs.
