Cutting Angles & Elevation


Overview

Elevation (also called lifting angle) is the degree at which hair is held away from the head before cutting. It is the single most important factor in determining the weight, layering, and overall shape of a haircut. Think of elevation as your main "design tool" — the higher you lift, the more layered and lightweight the result.


The Four Key Elevation Angles


| Elevation | Degree | Result | Haircut Type |

|---|---|---|---|

| No elevation / Natural fall | 0° | Maximum weight, no layers | Blunt / One-Length |

| Low elevation | 45° | Weight builds at perimeter, stacked | Graduated / Stacked |

| Perpendicular | 90° | Equal length inside and outside | Uniform Layer |

| Over-directed | Above 90° (up to 180°) | Interior shorter than exterior | Long-Layered |


Key Concepts


  • • 0-Degree Elevation (Natural Fall): Hair is combed straight down with no lifting. All hair falls to the same line, creating maximum weight at the perimeter. This is the classic blunt or one-length cut.
  • • 45-Degree Elevation: Hair is held halfway between lying flat and straight out. Creates a weight line and a stacked or wedge effect. Interior hair is slightly shorter; exterior hair holds the weight.
  • • 90-Degree Elevation: Hair is held perpendicular (straight out) from the head. Interior and exterior lengths are equal, producing a uniform or equal-length layer cut.
  • • Above 90-Degree Elevation / Overdirection: Hair is pushed or combed past 90 degrees toward a guide. Interior layers become shorter than the exterior, producing movement while preserving outside length — the long-layered effect.

    • Key Terms

  • • Elevation – The angle at which a section of hair is held from the head before cutting
  • • Natural fall – The direction hair falls due to gravity without any lifting (0 degrees)
  • • Weight line – The area of a haircut where the most length and density concentrate, creating a visible ridge or shelf
  • • Overdirection – Combing hair away from its natural fall toward a guide to build length or weight in a specific area
  • • Cutting line – The line along which hair is combed and held in tension before the shears cut

    • > ### ⚠️ Watch Out For

    > - Confusing elevation with overdirection — elevation is the angle you hold the hair; overdirection is the direction you comb it away from natural fall

    > - Assuming higher elevation always means shorter hair — at above 90 degrees, the interior is shorter but the exterior retains length

    > - Forgetting that 0 degrees produces maximum weight, not minimum — this trips up many students

    Sectioning & Parting


    Overview

    Proper sectioning and the use of guides are the architectural blueprints of every haircut. Without accurate sections and a reliable guide, no haircut can be executed consistently or precisely. The Texas Board exam expects you to know the function of each type of guide and the standard sectioning landmarks on the head.


    Head Landmarks


  • • Apex – The highest point on top of the head; a critical landmark for sectioning and determining how gravity will affect hair fall
  • • Crest area – The widest part of the head, roughly above the ears
  • • Nape – The lowest part of the hairline at the back of the neck
  • • Temple – The area above and in front of the ears

    • Standard Sectioning


    The Four Basic Sections:

    1. Start with a center part from the forehead to the nape

    2. Add a horizontal (ear-to-ear) part across the top of the head

    3. This creates two front sections and two back sections


    The Horseshoe Section (Crest Section):

  • • Separates the top and crown from the sides and back
  • • Follows the curve of the head from one temple over the apex to the other temple
  • • Commonly used when beginning layered cuts to isolate the interior

    • Types of Guides


    | Guide Type | How It Works | Effect Created |

    |---|---|---|

    | Stationary Guide | Fixed in one position; all sections brought TO it | Builds layers / graduation |

    | Traveling Guide (Moving Guide) | Moves with each new parting; small amount of previously cut hair included | Maintains consistent length progression |


  • • Stationary guide: Think of it as the "anchor." You always return to the same spot. Because sections farther away must travel to reach it, layers are created.
  • • Traveling guide: Think of it as a "companion." It moves with you parting by parting, keeping a uniform length as you progress.

    • Key Terms

  • • Guide (Guideline) – The first section cut; establishes length and shape for all subsequent sections
  • • Traveling guide – A moving guide that includes a small amount of previously cut hair in each new parting
  • • Stationary guide – A fixed guide to which all sections are brought to be cut
  • • Horseshoe section – The parting that separates the top/crown from the sides and back
  • • Apex – The highest point on top of the head
  • • Overdirection – Combing hair away from natural fall toward a guide to manipulate weight or length

    • > ### ⚠️ Watch Out For

    > - Mixing up stationary vs. traveling guides — remember: stationary = stays put and creates layers; traveling = moves and maintains length

    > - Forgetting the apex as a key reference point — exam questions often reference it when describing sectioning for layered cuts

    > - Assuming all haircuts use the same four sections — many specialty cuts require additional or different partings

    Hair Cutting Tools & Their Use


    Overview

    The Texas Board exam tests your knowledge of when, why, and how to use each cutting tool — including the correct safety procedures. Selecting the wrong tool for a hair type or texture is a common error in both the practical exam and real-world practice.


    Tool-by-Tool Breakdown


    #### ✂️ Shears (Scissors)

  • • Used for the majority of precision cutting techniques
  • • Palming the shears: When combing between cuts, remove your thumb from the thumb ring and rotate the shears to rest against the palm. This is the correct and required safety technique.
  • • Never hold open shears while combing — this is a major safety and exam error

    • #### ✂️ Thinning Shears (Blending / Texturizing Shears)

  • • Have one or two notched (serrated) blades
  • • Purpose: Remove bulk, blend weight lines, soften harsh edges
  • • They do not dramatically change the overall length
  • • Best used after the primary cut shape is complete

    • #### 🪒 Razor

  • • Creates soft, feathered, tapered ends on straight hair
  • • NOT recommended for curly or wavy hair — the razor frays the cuticle, causing frizz and undesirable texture
  • • Always used with a guard/comb or on wet hair for control

    • #### ⚡ Clippers vs. Trimmers (Edgers)


    | Tool | Size | Purpose |

    |---|---|---|

    | Clippers | Larger | Cut bulk hair throughout the head |

    | Trimmers / Edgers | Smaller, finer teeth | Detailing, outlining, finishing edges |


    Texturizing Techniques


    | Technique | Description | Result |

    |---|---|---|

    | Point Cutting | Shear tips inserted vertically into hair ends | Soft, broken, feathered edge |

    | Notching | Shears moved into ends at a steeper angle | Deeper, chunkier texture and separation |


    Key Terms

  • • Palming the shears – Safely resting shears in the palm by removing the thumb from the ring while combing
  • • Thinning shears – Notched-blade shears used to remove bulk and blend weight lines
  • • Point cutting – Inserting shear tips vertically into ends to create a soft, broken edge
  • • Notching – A deeper version of point cutting that creates chunkier texture and separation
  • • Clippers – Larger electrical tools for bulk hair removal
  • • Trimmers/Edgers – Smaller electrical tools for detailing and outlining

    • > ### ⚠️ Watch Out For

    > - Razor on curly/wavy hair — this is a classic exam trap. Razors are for straight hair only

    > - Forgetting to palm the shears while combing — the board exam may specifically test this safety step

    > - Confusing point cutting and notching — both go into the ends, but notching has a steeper angle and creates more dramatic texture

    Basic Haircut Structures


    Overview

    All haircuts, no matter how complex, are built from four basic forms (structures). Understanding what elevation and technique creates each form is the foundation of hair cutting theory and a guaranteed topic on the Texas Board exam.


    The Four Basic Haircut Structures


    #### 1. 🔵 Blunt Cut (One-Length Cut)

  • • Elevation: 0 degrees
  • • Weight: Maximum — all at the perimeter
  • • Weight line location: At the very ends (perimeter) of the hair
  • • Characteristic: All hair falls to the same line with no layering
  • • Example: Classic bob, straight one-length style

    • #### 2. 🟡 Graduated Cut (Stacked / Wedge)

  • • Elevation: 45 degrees (low graduation)
  • • Weight: Built up at the perimeter, creating a stacked or wedge effect
  • • Characteristic: Lengths progressively increase from interior to exterior; a visible weight line forms in the mid-lengths
  • • Example: Classic wedge, stacked bob

    • #### 3. 🟢 Uniform Layer Cut

  • • Elevation: 90 degrees
  • • Weight: Evenly distributed throughout
  • • Characteristic: Interior and exterior hair are cut to the same length; no weight line
  • • Example: Classic round or uniform layer cut

    • #### 4. 🔴 Long-Layered Cut (Increase-Layered Cut)

  • • Elevation: Above 90 degrees / overdirected
  • • Weight: At the exterior/perimeter; interior is shorter
  • • Characteristic: Interior layers are shorter than exterior; movement and volume without sacrificing length
  • • Example: Classic long layer, shag

    • Comparison at a Glance


    | Structure | Elevation | Interior vs. Exterior Length | Weight Location |

    |---|---|---|---|

    | Blunt | 0° | Same (no layers) | Perimeter |

    | Graduated | 45° | Interior slightly shorter | Mid-length perimeter |

    | Uniform Layer | 90° | Equal throughout | Evenly distributed |

    | Long-Layered | Above 90° | Interior shorter | Exterior / perimeter |


    Additional Structure Concept


  • • Disconnected haircut – A cut where two or more sections do not blend or graduate into each other, creating a dramatic contrast in length. This is an intentional design choice, not a mistake.

    • Key Terms

  • • Blunt cut – One-length cut at 0-degree elevation; maximum weight at perimeter
  • • Graduated cut – Cut at 45 degrees creating a stacked, wedge effect with a weight line
  • • Uniform layer – Cut at 90 degrees; all lengths equal inside and out
  • • Long-layered cut – Cut above 90 degrees; interior shorter than exterior
  • • Weight line – The ridge or shelf created by a concentration of length at a specific point
  • • Disconnected haircut – Intentional lack of blending between sections creating dramatic length contrast

    • > ### ⚠️ Watch Out For

    > - Confusing graduated and long-layered cuts — both have interior shorter than exterior, but graduated uses 45° and builds a weight line at the perimeter, while long-layered uses above 90° and keeps weight at the exterior

    > - Assuming uniform layers = short hair — uniform layering just means equal length throughout, not necessarily short

    > - Forgetting that the weight line in a blunt cut is at the perimeter, not in the interior

    Safety, Sanitation & Client Consultation


    Overview

    Texas state board rules on sanitation are non-negotiable. Proper disinfection between clients and correct pre-service consultation are both tested on the written exam and observed during the practical. These procedures protect the health of clients and practitioners alike.


    Texas Sanitation Requirements


  • • All non-electrical implements (shears, combs, brushes) must be:

    • 1. Cleaned first — remove all visible debris

    2. Disinfected — submerged or treated with an EPA-registered disinfectant solution

    3. This must happen between every client, without exception


  • • Electrical tools (clippers, trimmers) cannot be submerged; they must be disinfected with a spray or wipe of an EPA-registered disinfectant on the blade and exterior surfaces

    • Pre-Service Sanitation Steps

    1. Wash hands before beginning any service

    2. Place a neck strip between the client's skin and the cutting cape

    - Prevents the cape from directly touching the client's skin

    - Maintains sanitation standards and client comfort


    Client Consultation


    A thorough consultation should assess:

  • • Desired result – What does the client want?
  • • Lifestyle – How much time do they have for styling?
  • • Hair texture – Fine, medium, coarse?
  • • Hair density – Thin, normal, thick?
  • • Growth patterns – Cowlicks, whorls, nape patterns
  • • Face shape – Round, oval, square, heart, etc.
  • • Previous chemical services – Color, relaxer, perm (all affect how hair behaves when cut)

    • Key Concepts


    Cowlick:

  • • A section of hair that grows in a circular or opposing direction from surrounding hair
  • • Can cause hair to stand up or part in an unintended direction
  • • Must be accounted for in the design — never cut against it without planning for the result

    • Why Wet Hair Before Cutting:

  • • Wetting swells the cuticle, making hair more manageable and uniform
  • • Allows for more precise, even cutting with less resistance
  • • Makes it easier to see true length and weight distribution
  • • Note: Some techniques (dry cutting, curl cutting) intentionally use dry hair — but most standard cuts begin on wet hair

    • Key Terms

  • • EPA-registered disinfectant – A disinfecting solution approved by the Environmental Protection Agency for use on salon tools
  • • Neck strip – A paper or cloth strip placed between skin and cape for sanitation and comfort
  • • Cowlick – Hair that grows in a circular or opposing pattern, affecting style and cut design
  • • Consultation – Pre-service assessment of the client's desires, hair characteristics, and lifestyle needs

    • > ### ⚠️ Watch Out For

    > - The order of sanitation matters: clean FIRST, then disinfect — skipping cleaning means disinfectant cannot work properly

    > - Electrical tools cannot be submerged in liquid — never put clippers or trimmers in a disinfectant jar

    > - Forgetting to use a neck strip — this is commonly tested on the practical exam

    > - Cowlicks are not defects — they are growth patterns that must be incorporated into the design, not cut away carelessly
