Cutting Fundamentals
Core Concepts
Elevation is the most critical variable in hair cutting — it controls weight distribution and shape throughout the entire haircut.
| Elevation Angle | Result |
|---|---|
| 0° (no lift) | One-length/blunt cut — maximum weight |
| 45° | Graduated cut — stacked, angled, weight-building |
| 90° | Uniform layer cut — even layering, removes weight |
| Above 90° | Over-direction — adds length/weight in a specific area |
Key Concepts Defined
• Cutting Angle (Finger Angle): The angle at which fingers are held when cutting a section. Determines shape and weight distribution.
• Elevation: The angle at which a section of hair is held away from the head before cutting.
• Parting (Part): A line that divides hair into workable sections. Consistent partings = precise, even results.
• Tension: The amount of stretching applied to a hair section during cutting.
• Over-Direction: Combing hair beyond its natural fall (past 90°) toward a specific point before cutting.
Guides
| Guide Type | How It Works | Best Used For |
|---|---|---|
| Stationary Guide | Stays in one place; all sections are brought to it | One-length and blunt cuts |
| Traveling Guide | Moves with each new section cut | Layered and graduated cuts |
Key Terms
• Elevation
• Cutting angle
• Tension
• Stationary guide
• Traveling guide
• Parting
• Over-direction
⚠️ Watch Out For
• Tension trap: High tension on wet hair causes it to spring back shorter when dry. Always account for elasticity, especially on curly or fine hair.
• Elevation confusion: Students often confuse 45° (graduated) with 90° (uniform layers). Remember: 45° builds weight; 90° removes weight.
• Over-direction is NOT the same as elevation — it refers to direction (where hair is combed), not how high it is held.

Haircut Styles & Shapes
Style Breakdown
#### One-Length / Blunt Cut (Bob)
• Elevation: 0° (no lift)
• Weight: Maximum weight at the perimeter
• Shape: Clean, even line; hair falls to the same level
• Bob Specific: Falls between ears and shoulders; classic version is the foundational cut of cosmetology
#### Graduated Cut
• Elevation: ~45°
• Effect: Stacked, angled, weight-builds on the exterior
• Mechanism: Shorter layers stack on top of longer underneath layers
#### Uniform Layered Cut
• Elevation: 90° (straight out from the head)
• Effect: Even layering throughout; removes weight
#### Asymmetrical Cut
• Two sides cut to different lengths
• Creates an unbalanced, directional design
• One side is intentionally longer than the other
Anatomy Reference: The Occipital Bone
• Location: The protruding bone at the back of the skull
• Why It Matters: Its position directly affects where weight builds in graduated cuts and where the nape section begins. A low occipital bone will cause stacking to appear lower; a high occipital bone causes stacking to appear higher.
Key Terms
• Blunt cut
• Graduated haircut
• Uniform layer
• Asymmetrical haircut
• Occipital bone
• Perimeter
• Weight line
⚠️ Watch Out For
• Bob ≠ all bobs are one-length. The exam may reference angled bobs (graduated) — know the difference.
• Occipital bone questions often appear in context of where weight will fall in a graduated cut. Low bone = lower stack; high bone = higher stack.
• Do not confuse over-direction (direction hair is combed) with elevation (how high hair is held).

Texturizing & Specialty Techniques
Technique Comparison Chart
| Technique | Tool Used | Effect Created | Best For |
|---|---|---|---|
| Point Cutting | Shears (tips) | Soft, textured, less blunt ends | All hair types, blending |
| Notching | Shears (tips) | Jagged, chipped, dramatic separation | Edgy, defined styles |
| Slithering (Effilating) | Shears | Tapered, bulk removed, gradual taper | Thick hair, blending |
| Channel Cutting | Shears | Removes interior bulk, maintains length | Heavy, dense hair |
| Razor Cutting | Straight/feather razor | Soft, feathered, tapered ends | Fine to medium straight hair |
| Thinning Shears | Serrated shears | Bulk removal without changing length | High-density hair |
Technique Deep Dives
• Point Cutting: Tips of shears cut into the ends at a vertical angle — creates softness and removes blunt weight
• Slithering/Effilating: Shears open and close while sliding down the strand — gradual taper and bulk removal
• Notching: More dramatic than point cutting; creates a jagged, separated finish
• Razor Cutting: Slices through hair for feathered ends; avoid on curly or coarse hair (causes frizz)
• Channel Cutting: Shears inserted and cut vertically or diagonally through a section — removes interior bulk
• Thinning Shears: One or both blades are serrated/toothed — removes bulk, not length
Key Terms
• Point cutting
• Notching
• Slithering / Effilating
• Razor cutting
• Thinning shears / Texturizing shears
• Channel cutting
• Texturizing
⚠️ Watch Out For
• Razor cutting on curly/coarse hair = frizz. This is a classic exam trap. Razors are for fine to medium straight hair only.
• Know the difference between point cutting (soft, subtle) and notching (dramatic, jagged) — they use the same tool but produce different effects.
• Thinning shears remove bulk, NOT length — this distinction appears frequently on board exams.
• Slithering ≠ thinning shears — slithering is a technique with regular shears; thinning shears are a tool.

Tools, Safety & Sanitation
Shear Mechanics & Proper Handling
#### Finger Placement in Shears
• Thumb: Goes in the thumb ring (controls the moving blade)
• Ring Finger: Goes in the finger grip (larger ring)
• Pinky: Rests on the finger brace for control and stability
• Moving Blade: Controlled by the thumb (upper blade moves)
• Stationary Blade: The lower blade remains still during cutting
#### Safe Handling Practices
• Palming the Shears: Rotating the thumb out of the thumb ring and folding shears into the palm while combing — prevents injury during transitions
• Passing Shears: Always pass with handles extended toward the receiver, blades closed — never point tips at another person
NY State Sanitation Protocol for Shears
1. Remove all hair and debris from the shears
2. Immerse in or wipe with an EPA-registered disinfectant approved for non-porous tools
3. Must comply with NY State Board regulations between every client
Key Terms
• Palming the shears
• Finger grip (ring)
• Thumb ring
• Finger brace
• EPA-registered disinfectant
• Non-porous tools
• Stationary blade
⚠️ Watch Out For
• The ring finger goes in the larger ring — NOT the index or middle finger. This is frequently tested.
• The thumb blade moves; the lower blade is stationary — reversed answers are a common distractor.
• NY State requires an EPA-registered disinfectant — "cleaning" alone is insufficient. Know the full protocol.
• Palming shears is a safety technique — the exam may ask why it's done (to prevent accidental cuts while combing).

Client Consultation & Safety
The Consultation Process
A client consultation is performed before every service. Its purposes include:
• Determining the client's desired outcome
• Evaluating hair type, growth patterns, and condition
• Setting realistic expectations
• Preventing costly, irreversible mistakes
Hair Analysis Terms
• Hair Density: Number of hair strands per square inch (thin, medium, thick)
- High density → may require texturizing to remove bulk
- Low density → blunt cuts recommended to maximize fullness
• Cowlick: Hair that grows in a circular or opposing direction, causing it to stand up or lie differently
- Must be accounted for to avoid uneven or lifted results after cutting
- Always analyze before beginning the cut
Sectioning for Cutting
Four-Section Part (Cross-Sectioning):
• Center part: Forehead to nape
• Ear-to-ear part: Horizontal across the crown
• Creates four quadrants for a systematic, controlled foundation
• Ensures consistency throughout the haircut
Draping Protocol (NY State)
• Purpose: Protects client's clothing and skin from cut hair, water, and chemicals
• NY State Requirement: A neck strip or towel must be placed between the cape and the client's skin for sanitary purposes — the cape must never touch bare skin
Key Terms
• Client consultation
• Hair density
• Cowlick
• Four-section part / Cross-sectioning
• Draping
• Neck strip
• Growth patterns
⚠️ Watch Out For
• Draping protocol: The neck strip goes between cape and skin — a cape touching bare skin is a sanitation violation in NY State.
• Cowlick questions often involve where the hair will end up after cutting — you must analyze cowlicks before you cut, not after.
• Hair density ≠ hair texture. Density = how many strands; texture = the diameter/coarseness of individual strands.
• A consultation must happen before every service — not just new clients.
