What Is Your Hair Type? A Complete Guide to Understanding Your Hair

Understanding your hair type is the foundation of building an effective hair care routine.

Just as skin types vary, hair comes in different textures, densities, and porosity levels — each requiring specific care to look and feel its best.

Yet many people struggle to identify their hair type, leading to frustration with products that don't work or routines that fall flat.

This guide will help you determine your hair type, understand what it means, and choose the right natural, plant-based products to support healthy, beautiful hair.

Why Hair Type Matters

Your hair type influences:

• How much moisture your hair needs
• Which oils and butters work best
• How often you should wash
• What styling techniques suit your texture
• How your hair responds to environmental factors

When you understand your hair type, you stop guessing and start giving your hair exactly what it needs.

The Hair Typing System

The most widely used hair typing system was developed by hairstylist Andre Walker. It categorizes hair into four main types (1-4) with subcategories (A, B, C) based on curl pattern and texture.

Type 1: Straight Hair

Type 1 hair has no curl pattern and lies flat from root to tip.

1A: Very straight, fine, and soft. Tends to be oily and difficult to hold a curl.

1B: Straight with slightly more body and volume than 1A. Medium texture.

1C: Straight but coarse and thick. May have slight bends or waves.

Characteristics:

• Reflects light easily, giving a shiny appearance
• Oil travels down the hair shaft quickly
• Can become greasy faster than other types
• Resistant to styling and holding curls

Type 2: Wavy Hair

Type 2 hair falls between straight and curly, with an S-shaped wave pattern.

2A: Fine, thin waves that are easy to straighten or curl. Slight wave pattern, mostly at the ends.

2B: Medium-textured waves that form an S-shape. More defined wave pattern from mid-length down.

2C: Thick, coarse waves that start closer to the roots. Prone to frizz and more resistant to styling.

Characteristics:

• Tends to be frizz-prone, especially in humidity
• Can be weighed down by heavy products
• Benefits from lightweight moisture
• Wave pattern can vary throughout the head

Type 3: Curly Hair

Type 3 hair has well-defined, springy curls that form an S or spiral shape.

3A: Loose, large curls with a lot of shine and definition. Curls are about the size of sidewalk chalk.

3B: Medium curls with a springy texture. Curls are about the size of a marker. More volume and less shine than 3A.

3C: Tight curls or corkscrew pattern. Curls are about the size of a pencil or straw. Dense and full with lots of volume.

Characteristics:

• Prone to dryness and frizz
• Needs regular moisture and hydration
• Benefits from leave-in conditioners and oils
• Can shrink significantly when dry

Type 4: Coily/Kinky Hair

Type 4 hair has tight coils or a zigzag pattern. It's the most fragile hair type and requires gentle handling.

4A: Soft, tightly coiled hair with an S-pattern. Coils are about the size of a crochet needle.

4B: Z-shaped pattern with sharp angles. Less defined curl pattern, more cotton-like texture.

4C: Very tight, densely packed coils with minimal definition. Extremely fragile and shrinks up to 75% of its actual length.

Characteristics:

• Most prone to dryness and breakage
• Requires deep moisture and protective styling
• Benefits from rich butters and oils
• Shrinkage is significant
• Needs gentle detangling and minimal manipulation

Beyond Curl Pattern: Other Hair Characteristics

Hair type is just one piece of the puzzle. To truly understand your hair, consider these additional factors:

Hair Density

Density refers to how many individual strands you have on your head.

• Low density: You can easily see your scalp. Hair feels thin.
• Medium density: Scalp is somewhat visible. Average thickness.
• High density: Scalp is difficult to see. Hair feels thick and full.

Hair Porosity

Porosity measures how well your hair absorbs and retains moisture.

Low porosity:

• Cuticles are tightly closed
• Water beads up on hair surface
• Products sit on top rather than absorbing
• Takes a long time to dry
• Needs lightweight oils and heat to open cuticles

Medium porosity:

• Cuticles are slightly raised
• Absorbs and retains moisture well
• Easiest hair type to maintain
• Responds well to most products

High porosity:

• Cuticles are very open or damaged
• Absorbs moisture quickly but loses it just as fast
• Prone to frizz and tangles
• Needs heavy butters and sealants
• Benefits from protein treatments

Hair Thickness (Strand Diameter)

• Fine: Individual strands are thin and delicate. Can be easily weighed down.
• Medium: Average strand thickness. Most versatile.
• Coarse: Thick individual strands. Strong but can be resistant to styling.

How to Determine Your Hair Type

Step 1: Wash and Air Dry

Start with freshly washed hair. Don't use any styling products. Let your hair air dry completely in its natural state.

Step 2: Observe Your Curl Pattern

Look at your hair in its natural, product-free state. Is it straight, wavy, curly, or coily? Compare it to the descriptions above.

Step 3: Test Your Porosity

Take a clean strand of hair and place it in a glass of water.

• Floats on top = Low porosity
• Floats in the middle = Medium porosity
• Sinks to the bottom = High porosity

Step 4: Check Your Density

Pull your hair into a ponytail. Measure the circumference:

• Less than 50mm = Low density
• 50-75mm = Medium density
• More than 100mm = High density

Step 5: Assess Strand Thickness

Take a single strand and compare it to a piece of thread:

• Thinner than thread = Fine
• Same as thread = Medium
• Thicker than thread = Coarse

Common Hair Care Mistakes by Type

Straight Hair

• Using too much product
• Washing too frequently, stripping natural oils
• Applying conditioner to roots

Wavy Hair

• Brushing dry hair
• Using products that are too heavy
• Not defining waves while damp

Curly Hair

• Using sulfates that strip moisture
• Not using enough conditioner
• Towel-drying roughly (causes frizz)

Coily Hair

• Not moisturizing daily
• Detangling when dry
• Using heat too frequently
• Skipping protective styles

Building Your Hair Care Routine

Once you know your hair type, build a routine that includes:

1. Cleansing

Choose a gentle, sulfate-free cleanser appropriate for your hair type. Straight and wavy hair may need more frequent washing; curly and coily hair benefits from less frequent cleansing.

Try our Eco-Friendly Shampoo Bar or 3-in-1 Shampoo, Bath & Shower Gel for plant-based, gentle cleansing.

2. Conditioning

All hair types need conditioning, but the type and amount vary. Fine hair needs lightweight conditioners; coarse, curly, and coily hair needs rich, creamy formulas.

Our Zero Waste Conditioner Bar works beautifully for all hair types.

3. Moisturizing

Use leave-in treatments, oils, or creams based on your porosity and texture. Apply to damp hair for best absorption.

4. Styling

Choose styling products that enhance your natural texture rather than fighting it.

5. Protecting

Protect hair from heat, environmental damage, and friction. Use silk or satin pillowcases and protective styles when needed.

Final Thoughts

Your hair type is unique to you — and it may even vary across different areas of your head.

Understanding your hair's natural texture, porosity, density, and thickness empowers you to make informed choices about products and routines.

Natural, plant-based hair care works with your hair's structure, not against it. When you choose ingredients that complement your hair type, you support its health, strength, and natural beauty.

Because healthy hair isn't about forcing it into a mold. It's about understanding what you have and giving it exactly what it needs.
