8.2 Elevation, Guidelines and Overdirection

Elevation, Guidelines and Overdirection

Exam Focus: The written exam asks which elevation produces which silhouette and which guideline produces which length distribution; the practical exam asks you to demonstrate a 0-degree perimeter and a 90-degree layered cut with vertical partings. Learn elevation and guideline as a pair, because a haircut is defined by the combination, not by either one alone.

1. Elevation (Projection) Angles & Silhouette Effects

Elevation, also known as projection or lifting, is the degree or angle at which a subsection of hair is held, elevated, or lifted away from the natural curvature of the head prior to cutting. Elevation is the single most important factor determining whether a haircut builds weight, graduations, or layers.

The Four Foundational Elevation Degrees

Rule of Thumb for State Boards: Elevation below 90° builds weight and density; elevation at 90° or higher removes weight and creates layers.

2. Cutting Lines & Guideline Classifications

Cutting Line (Cutting Angle)

The cutting line is the angle at which the stylist's fingers and cutting shears are held when cutting the hair. It determines the ultimate shape and line of the cut (e.g., horizontal, vertical, diagonal, or beveled relative to the section parting).

Stationary vs. Traveling Guidelines

A guideline (also called a guide) is a section of hair that determines the length to which subsequent hair will be cut. Guidelines are established at the very beginning of the haircut:

STATIONARY GUIDELINE:               TRAVELING (MOVABLE) GUIDELINE:

   Section 1 [GUIDE] (Fixed)           Section 1 [Cut] ──> becomes Guide for Section 2

      │     │     │                                               ▼

(All combed to Section 1)                                         │
                                                                  ▼
                                       Section 3 [Cut] ──> becomes Guide for Section 4

1. Stationary Guideline:
   • A fixed guideline that does not move throughout the haircut.
   • All subsequent subsections are combed and projected directly to this single stationary anchor point.
   • Primary Use: Used in blunt/one-length cuts and long-layered cuts (where all hair is overdirected to a stationary top guide at the apex), or to create dramatic length increases toward the front or back.
2. Traveling (Movable) Guideline:
   • A guideline that moves along with the progression of the haircut.
   • A thin slice of the previously cut subsection is incorporated into the next subsection to serve as its length reference, and the remainder is dropped away.
   • Primary Use: Essential for uniform layered haircuts (90°), progressive graduation, and short tapered shaping.

3. Overdirection Principles & Length Expansion

Overdirection occurs when hair is combed away from its natural falling position toward a stationary or traveling guideline positioned elsewhere on the head, rather than being lifted straight out perpendicular to its origin.

How Overdirection Alters Haircut Dimensions

• Principle of Length Expansion: Overdirecting hair in one direction creates an increase in length and weight in the exact opposite direction.
• Front-to-Back Overdirection: Combing front side sections backward toward a stationary guide behind the ear preserves maximum length in front, creating an elongated front perimeter (A-line/forward-angled silhouette).
• Back-to-Front Overdirection: Combing rear sections forward toward a guide at the front hairline preserves length in the back, creating a reverse wedge/shag shape.
• Upward Overdirection: Combing bottom perimeter hair straight up to a stationary guide at the crown/apex creates long layers while leaving the bottom length intact.

4. Elevation and Guideline as a Pair

A haircut is defined by the combination of elevation and guideline, not by either alone. Four combinations cover almost everything.

The New York practical examination requires exactly two of these in sequence: establish the perimeter using a zero-degree guideline with the front angled, then perform a layered cut using vertical partings at 90-degree elevation. Chapter 14 covers the procedure in full.

5. Overdirection in Practice

Overdirection combs hair away from its natural fall to a guideline held elsewhere. Because the hair travels further to reach the guideline, it is cut longer than it would otherwise be, so length increases in the direction the hair was overdirected away from.

Three standard uses:

• Length increase toward the front. Overdirecting side sections back to a stationary guideline at the back produces a face-framing shape that increases in length toward the face — the effect the practical examination calls "the front will be angled".
• Building weight in a corner. Overdirecting to a stationary guideline concentrates length and weight at that point.
• Blending a disconnection. Overdirecting across a section fills a gap between two lengths.

The counterpart error is unintentional overdirection: combing a subsection at a slight angle without meaning to, which lengthens that subsection and produces a stepped or uneven line. The remedy is disciplined partings, consistent tension and cross-checking, covered in section 8.6.

6. Tension

Tension is the amount of pull applied while combing and holding a subsection, and it is the most common invisible cause of an uneven haircut.

• Consistent tension across every subsection is what makes a cut repeatable.
• Maximum tension on straight hair produces the cleanest blunt line, but it also produces the biggest surprise if the hair has any wave — the cut springs shorter as it dries.
• Minimum tension is used on curly, coily and wavy hair, around growth patterns such as cowlicks and whorls, and at the nape hairline, where pulling hair straight produces a line that lifts as soon as it is released.
• Never cut a curly client's hair at maximum tension and expect the wet length to hold. Curly hair shrinks, sometimes by half.
