Your curl pattern is as unique as your fingerprint, and understanding it transforms how you care for your hair. The curl type system—ranging from 2A waves to 4C coils—helps you identify your natural texture so you can choose products and techniques that actually work. Whether you're managing your curls at home or searching for a curly hair stylist near me who specializes in your specific texture, knowing your curl type is the foundation for healthy, beautiful hair.
What Is the Curl Type System?
The curl type classification system categorizes hair into four main types (Type 1-4), with subcategories A, B, and C representing increasing curl tightness. Created by hairstylist Andre Walker in the 1990s, this system remains the gold standard for identifying hair textures in 2025.
Type 2: Wavy hair with an S-shaped pattern
Type 3: Curly hair with defined spiral curls
Type 4: Coily hair with tight zigzag or corkscrew patterns
Understanding your specific curl type helps you select the right products, determine optimal wash frequency, and master styling techniques tailored to your hair's needs.
Type 2: Wavy Hair Patterns
2A Wavy Hair: Fine and Loose
Type 2A hair features loose, barely-there S-waves that lie close to the head. This is the finest wavy texture, often appearing almost straight when wet.
Characteristics:
- Fine texture with minimal volume
- Prone to becoming greasy quickly
- Easily weighed down by heavy products
- Heat-styles easily but loses curl pattern quickly
Best Care Practices:
- Use lightweight, volumizing mousses
- Wash every 2-3 days with sulfate-free shampoo
- Avoid heavy oils and butters
- Air-dry or diffuse on low heat
2B Wavy Hair: Medium Texture with Definition
Type 2B hair shows more defined S-waves that start mid-shaft and have moderate volume. This texture sits right between straight and curly.
Characteristics:
- Medium texture with natural body
- Waves become more defined when products are applied
- Can experience some frizz in humid conditions
- Holds styles relatively well
Best Care Practices:
- Apply curl-enhancing creams to damp hair
- Use the "squish to condish" method for hydration
- Try sea salt sprays for beachy texture
- Refresh second-day hair with water and leave-in conditioner
2C Wavy Hair: Thick with Strong S-Pattern
Type 2C is the waviest of the wavy textures, featuring well-defined S-waves from roots to ends with increased volume and texture.
Characteristics:
- Thicker, coarser texture
- Prone to frizz and tangles
- Waves start at the roots
- Can appear more curly than wavy in humid weather
Best Care Practices:
- Deep condition weekly for moisture
- Use anti-frizz serums and curl creams
- Detangle gently with wide-tooth comb when wet
- Consider the Curly Girl Method for definition
Type 3: Curly Hair Patterns
3A Curly Hair: Loose Spiral Curls
Type 3A hair features loose, well-defined spiral curls about the size of sidewalk chalk. These curls have a natural shine and bounce.
Characteristics:
- Springy curls with S-shaped pattern
- Naturally shiny with good moisture retention
- Circumference roughly the size of a marker
- Responds well to product and styling
Best Care Practices:
- Co-wash 2-3 times weekly
- Use curl-defining creams and gels
- Apply products using the rake and shake method
- Pineapple hair at night to preserve curls
3B Curly Hair: Medium Springy Curls
Type 3B curls are tighter than 3A, forming spirals about the size of a Sharpie marker. These curls have significant volume and bounce.
Characteristics:
- Well-defined ringlets from root to tip
- Circumference of a pen or marker
- Prone to dryness and frizz
- Significant volume and density
Best Care Practices:
- Deep condition every wash
- Use the LOC method (Liquid, Oil, Cream)
- Refresh curls with water-based sprays
- Sleep on satin or silk pillowcases
3C Curly Hair: Tight Corkscrew Curls
Type 3C features the tightest curl pattern in the Type 3 category, with corkscrew curls about the size of a pencil or straw.
Characteristics:
- Tightly packed, dense curls
- Circumference of a pencil or drinking straw
- High volume and density
- More prone to shrinkage and dryness
Best Care Practices:
- Moisturize daily with leave-in conditioners
- Use protein treatments monthly
- Detangle with plenty of conditioner
- Try twist-outs or braid-outs for definition
Type 4: Coily Hair Patterns
4A Coily Hair: S-Shaped Coils
Type 4A hair has a visible S-pattern when stretched, forming tight coils with excellent curl definition. These coils are about the size of a crochet needle.
Characteristics:
- Tightly coiled S-pattern
- More moisture retention than 4B or 4C
- Significant shrinkage (up to 75%)
- Circumference of a crochet needle
Best Care Practices:
- Pre-poo treatments before washing
- Use thick, creamy leave-in conditioners
- Seal moisture with heavy oils or butters
- Protective styles to retain length
4B Coily Hair: Z-Shaped Pattern
Type 4B hair has a less defined curl pattern, forming tight Z-shaped angles rather than spirals. This texture is densely packed and incredibly versatile.
Characteristics:
- Z-shaped or zigzag pattern
- Bends at sharp angles
- Extreme shrinkage (70-85%)
- Requires maximum moisture
Best Care Practices:
- Deep condition with every wash
- Use the LCO method (Liquid, Cream, Oil)
- Moisturize and seal daily
- Stretch hair with banding or threading
4C Coily Hair: Tightly Coiled with Minimal Definition
Type 4C is the tightest curl pattern, with strands that form tight, springy coils without a clearly defined curl pattern. This texture is delicate and requires gentle handling.
Characteristics:
- No visible curl pattern when unstretched
- Extreme shrinkage (up to 90%)
- Most fragile curl type
- Wire-like texture when dry
Best Care Practices:
- Handle hair gently to prevent breakage
- Keep hair moisturized at all times

How to Determine Your Curl Type
Step 1: Start with Clean, Product-Free Hair
Wash your hair with a clarifying shampoo to remove all product buildup. This gives you an accurate view of your natural texture.
Step 2: Let Your Hair Air Dry Naturally
Allow your hair to dry completely without touching, scrunching, or adding any products. Don't use heat tools.
Step 3: Examine Your Curl Pattern
Look at the shape your hair forms naturally. Is it wavy (S-shaped), curly (spiral), or coily (tight Z-pattern)?
Step 4: Measure Your Curl Circumference
Compare your curl size to common objects:
- Sidewalk chalk = 3A
- Sharpie marker = 3B
- Pencil/straw = 3C
- Crochet needle = 4A
- Pin or paperclip = 4B/4C
Step 5: Consider You May Have Multiple Curl Types
Many people have different curl patterns in different areas. Your crown might be 3B while your nape is 3C—this is completely normal.
Common Curl Care Mistakes to Avoid
Using the Wrong Products for Your Curl Type
Heavy butters and oils overwhelm fine 2A waves, while lightweight mousses won't provide enough moisture for 4C coils. Match product weight to your curl density.
Over-Washing Your Hair
Curly and coily hair types (3A-4C) don't need daily washing. Over-washing strips natural oils, leading to dryness and breakage. Most curl types thrive with 1-3 washes weekly.
Brushing Dry Curls
Dry brushing breaks curl clumps and creates frizz. Always detangle on wet, conditioner-coated hair using fingers or a wide-tooth comb.
Skipping Deep Conditioning
Deep conditioning treatments are non-negotiable for Types 3 and 4. These treatments restore moisture, improve elasticity, and reduce breakage.
Using Heat Without Protection
Heat styling without a protectant damages the curl pattern permanently over time. If you must use heat, always apply a heat protectant first and use the lowest effective temperature.

Frequently Asked Questions About Curl Types
Can your curl type change over time?
Yes, curl patterns can change due to hormones, medications, pregnancy, menopause, heat damage, chemical treatments, aging, and even stress. Some people notice looser curls after pregnancy, while others develop tighter patterns. Heat damage can permanently alter curl structure.
What is curl porosity and how does it relate to curl type?
Porosity measures how well your hair absorbs and retains moisture. Low porosity hair resists moisture, normal porosity balances well, and high porosity absorbs quickly but loses moisture fast. You can have any curl type with any porosity level—they're independent characteristics that both influence your hair care routine.
Do I need to follow the Curly Girl Method for all curl types?
The Curly Girl Method works excellently for Types 3 and 4, but Type 2 waves often need modifications. Wavy hair may require clarifying shampoo more frequently and lighter products than the traditional CGM recommends. Experiment to find what works for your specific texture.
How do I deal with multiple curl types on one head?
Work in sections and treat each area according to its needs. Your curliest sections may need more moisture and product, while looser areas need less. Layer products strategically—apply lighter products to fine areas first, then heavier products to coarser sections.
Why does my hair look different when wet versus dry?
Shrinkage causes this difference, especially in Type 4 hair. Water weight temporarily elongates curls, making them appear longer and looser. As hair dries, the natural curl pattern tightens and contracts, sometimes reducing visible length by 75-90%.
Can heat styling permanently change my curl pattern?
Yes, repeated heat styling without protection can permanently damage the protein bonds that create your curl pattern. This heat damage is cumulative and irreversible—you'll need to grow out damaged hair and cut it off. Always use heat protectant and the lowest effective temperature.
Styling Techniques for Each Curl Type
Best Methods for Type 2 Wavy Hair
The Plop Method: Wrap wet hair in a microfiber towel to encourage wave formation and reduce frizz while drying.
Beach Waves Technique: Scrunch sea salt spray into damp hair, then air-dry or diffuse for effortless texture.
Root Clipping: Use clips at the roots while drying to add volume and prevent flat, limp waves.
Best Methods for Type 3 Curly Hair
Rake and Shake: Rake products through sections with fingers, then shake hair to create curl clumps.
Shingling: Apply product to individual curl sections for maximum definition and shine.
Diffusing: Use a diffuser attachment on low heat to speed drying while maintaining curl pattern.
Best Methods for Type 4 Coily Hair
Twist-Outs: Create two-strand twists on wet hair, allow to dry, then unravel for defined curls.
Braid-Outs: Braid sections of hair while damp, dry completely, then unbraid for stretched, wavy texture.
The LOC/LCO Method: Layer Liquid, Oil, and Cream (or Liquid, Cream, Oil) to seal in maximum moisture.
Seasonal Curl Care Adjustments
Winter Curl Care (Cold, Dry Weather)
Cold air and indoor heating strip moisture from curls. Increase deep conditioning frequency, use heavier creams and butters, protect hair with satin-lined hats, and avoid going outside with wet hair to prevent breakage.
Summer Curl Care (Heat and Humidity)
Humidity causes frizz by allowing moisture to penetrate the hair shaft unevenly. Use anti-humidity products with silicones or oils, apply stronger hold gels, refresh curls more frequently, and protect hair from chlorine and salt water with leave-in conditioner before swimming.
Spring and Fall Transitions
As weather shifts, your hair needs adjustment time. Gradually transition between heavy and light products, pay attention to how your hair responds, and modify your routine based on daily humidity levels rather than calendar dates.
The Science Behind Curl Formation
Curl pattern is determined by the shape of your hair follicle. Straight hair grows from round follicles, while increasingly oval or asymmetrical follicles produce wavy, curly, and coily textures. The angle at which hair emerges from the scalp also affects curl formation.
Disulfide Bonds: These protein connections between hair strands create and maintain curl shape. Heat and chemical treatments break these bonds, which is how relaxers and perms work.
Hydrogen Bonds: These weaker bonds break when hair gets wet and reform as it dries. This is why you can temporarily reshape curls with water and styling products.
Cortex Structure: The internal structure of the hair shaft influences curl pattern. Curly hair has an asymmetrical cortex, causing one side to grow faster than the other, creating the curl.
Building Your Personalized Curl Care Routine
Step 1: Identify Your Complete Hair Profile
Beyond curl type, consider:
- Density: How many strands you have (thin, medium, thick)
- Porosity: How well hair absorbs moisture (low, normal, high)
- Width: Individual strand thickness (fine, medium, coarse)
- Elasticity: How much your hair stretches before breaking
Step 2: Test Products Systematically
Introduce one new product at a time so you can identify what works. Wait at least 2-3 wash cycles before judging effectiveness. Keep a hair journal noting products, techniques, and results.
Step 3: Establish Your Baseline Routine
Start with the basics:
- Cleansing method and frequency
- Conditioning approach
- Leave-in moisture
- Styling products
- Drying technique
- Nighttime protection
Step 4: Adjust Based on Results
Pay attention to how your hair responds:
- Too much frizz? Add more moisture or anti-humidity protection
- Lacks definition? Try different application techniques or stronger hold products
- Feels dry? Increase deep conditioning frequency
- Looks greasy? Use lighter products or reduce quantity
- Tangles easily? Add more slip with conditioner or detangling spray
Step 5: Maintain Consistency
Healthy curls require consistent care. Stick with your routine for at least 4-6 weeks before making major changes. Hair health improves gradually, not overnight.

Transitioning to Natural Curls
Growing Out Relaxed or Heat-Damaged Hair
Transitioning from chemically straightened to natural hair requires patience and strategy:
The Big Chop: Cut all relaxed or damaged hair at once for a fresh start with your natural texture.
Long-Term Transition: Gradually grow out natural hair while managing two textures (12-18 months typically). Use protective styles like braids, twists, or wigs to blend textures while growing.
Transitioning Tips:
- Deep condition weekly without exception
- Use protein treatments to strengthen demarcation line
- Keep hair in low-manipulation styles
- Trim gradually as new growth appears
- Be patient—healthy hair takes time
Embracing Your Natural Texture After Years of Heat Styling
If you've heat-styled for years, your curl pattern may be damaged. Focus on:
- Eliminating all heat for 3-6 months minimum
- Intensive moisture treatments weekly
- Protein-moisture balance maintenance
- Gentle handling and protective styling
- Realistic expectations about recovery time
Some heat damage is permanent and will only improve with trimming and new growth.
