Want better haircuts? It all starts with understanding hair types and how they affect cutting techniques. Hair grows straight, wavy, curly, or coily based on the follicle shape, and each type needs a specific approach for the best results. Here's a quick breakdown:
- Straight Hair: Needs clean, precise cuts to maintain its sleek look.
- Wavy Hair: Benefits from layers to reduce frizz and enhance natural movement.
- Curly Hair: Requires moisture-preserving cuts that maintain the curl pattern.
- Coily Hair: Needs shaping techniques that account for shrinkage and texture.
Key factors like texture, porosity, and density also guide cutting methods. For example, fine hair needs volume-boosting techniques, while thick hair benefits from layering to reduce bulk.
Quick Tips:
- Use Japanese steel shears for precision and durability.
- Match tools and methods to hair texture and density.
- For curly and coily hair, dry cutting often works best to preserve natural patterns.
Understanding these basics can make every haircut smoother and more tailored to individual needs. Dive into the full article for detailed techniques and tool recommendations.
Learning the Basics of Haircutting
Hair Types and Their Properties
Knowing the properties of hair is essential for using the right cutting techniques and professional tools.
4 Main Hair Types: Straight, Wavy, Curly, and Coily
Hair is categorized into four main types:
- Type 1 (Straight): Reflects the most light and tends to be oily .
- Type 2 (Wavy): Has a natural 'S' shape.
- Type 3 (Curly): Features well-defined 'S' or 'Z' curls.
- Type 4 (Coily): Characterized by tight, dense coils .
These categories help explain how texture and porosity impact cutting techniques.
Texture and Porosity
Hair texture plays a big role in how a cut feels and looks. It affects volume, weight, and flexibility . For instance:
- Fine hair benefits from techniques that add volume.
- Coarse hair often requires layered cuts to reduce heaviness .
Porosity, which dictates how hair retains moisture, also varies. Virgin curly hair, for example, tends to be more porous than straight hair . This affects both moisture retention and how the hair responds to cutting.
Hair Density and Cutting Methods
Hair density directly impacts the choice of cutting techniques:
- Fine, low-density hair: Longer layers help maintain volume at the roots.
- Fine, high-density hair: Targeted layering creates balanced fullness .
- Thick, high-density hair: Techniques like layering reduce bulk while keeping the shape intact. Undercuts are particularly effective for styles like bobs .

Professional Hair Cutting Tools
Japanese steel shears are renowned for their precision and performance, making them a staple in professional hair cutting.
Why Choose Japanese Steel Shears?
Japanese steel shears are crafted for accuracy, with a Rockwell hardness (HRC) of 58–63 that ensures the blades stay sharp for extended periods. The higher carbon content in the steel allows for a lighter design, reducing strain on the wrist, elbow, and shoulder during use .
Top-quality shears, like those in Shihan Shears' Legacy collection, feature convex blades for precise cutting. Though the initial cost ranges from $300 to $1,500, these tools can last 5 to 20 years with proper care .
Matching Shears to Hair Types
Choosing the right shears depends on both hair texture and cutting technique. Here's a quick guide to help you pair shears with different hair types:
| Hair Type | Recommended Shear Features | Optimal Blade Type |
|---|---|---|
| Fine Hair | Lightweight, sharp blades | Convex edges |
| Thick Hair | Durable blades, wider grips | Beveled or serrated |
| Curly Hair | Wider blades, smooth edges | Wet cutting blades |
| Coily Hair | Texturizing capabilities | Dry cutting blades |
Blade length also matters. Shorter blades are ideal for detailed work, while longer blades are better for cutting larger sections . Selecting the right shear features ensures better results and a smoother cutting experience.
Maintaining Shears for Long-Term Use
Proper care is key to keeping your shears in top condition:
- Daily Cleaning: After each use, clean the blades with warm, soapy water and dry thoroughly to prevent rust .
- Weekly Maintenance: Apply oil to the pivot point at a 45-degree angle, open and close the shears to spread the oil, and let them sit overnight .
- Regular Inspection: Check the tension settings to ensure clean cuts without pulling or folding hair. Store shears in a protective case with a soft lining to avoid damage and moisture exposure .
Avoid cutting non-hair materials or exposing the blades to high heat , as these can damage the alignment and tension of the shears. Proper maintenance not only extends their life but also ensures consistent performance.
Hair Type-Specific Cutting Methods
Cutting Straight Hair
Straight hair, known for its sleek and uniform structure, requires precise and consistent cuts. Its smooth texture highlights any unevenness, so accuracy is key. Here are some effective technique-style combinations:
| Style Goal | Cutting Technique |
|---|---|
| Classic Bob | Use a one-length cut with clean, horizontal lines |
| Adding Volume | Incorporate point cutting for soft, volumizing layers |
| Enhancing Movement | Create long layers with a gradual graduation |
| Reducing Weight | Texturize the ends strategically to remove bulk |
Be cautious with texturizing - too much can make fine hair look sparse. However, for thicker hair, selective weight removal can add movement and balance.
While straight hair demands precision, wavy hair thrives with methods that embrace its natural flow.
Cutting Wavy Hair
Wavy hair’s natural "S" shape calls for techniques that maintain its flow while minimizing frizz. Professional stylist April Ferri advises:
"A lot of people want to thin it out with thinning shears or razors, but that will usually just make wavy hair more frizzy" .
Key tips for cutting wavy hair:
- Cut when damp to highlight natural wave patterns
- Work with the wave patterns to reduce frizz and unnecessary manipulation
- Account for how waves will spring back when dry, affecting the final length
Long, soft layers can enhance the natural waves while reducing bulk, whereas shorter layers can add texture and volume without inducing frizz .
For curly and coily hair, even more specialized techniques are necessary to maintain the integrity of the curl.
Cutting Curly and Coily Hair
Curly and coily hair require a careful approach to preserve the natural curl pattern and reduce frizz. As Nubia Suarez, a salon owner in NYC, explains:
"It is best to cut curly hair in its natural and dry state" .
Here’s a breakdown of popular techniques tailored for curly and coily hair:
| Technique | Key Features | Ideal For |
|---|---|---|
| DevaCut | Dry cutting curl-by-curl | Highlighting defined curl patterns |
| Rezo Cut | Dry cutting that maintains length | Keeping length while adding volume |
| Curlsys | European dry cutting method | Enhancing curl definition and reducing frizz |
| CC1 Technique | Wet vertical cutting | Adding volume |
| Global Curl Concept | Dry cutting focused on frizz control | Preserving natural curl shape and texture |
Essential guidelines for curly and coily hair:
- Cut only after the hair is washed, dried, and detangled
- Ensure even distribution of length throughout
- Use circular cutting patterns to blend textures seamlessly
- Avoid razors or excessive texturizing to maintain the natural curl pattern
The choice between wet and dry cutting depends on the method. For example, techniques like the DevaCut and Rezo Cut are performed on dry hair, while the CC1 Technique requires wet hair . Always match the method to the curl type and the desired result.
