Cutting Tools & Equipment
Summary
Understanding the purpose, function, and maintenance of cutting tools is critical for both exam performance and professional practice. Texas state board examiners expect candidates to know how each tool is used and how it must be properly sanitized between clients.
Key Concepts
• Blunt cutting shears – Two straight, sharp blades; cut all hair cleanly for precise, defined lines
• Thinning shears – One or two notched (serrated) blades; remove bulk and blend without cutting all hair
- 30–45 teeth is the typical range
- Fewer teeth → more hair removed → more dramatic thinning
- More teeth → less hair removed → subtler blend
• Still blade (stationary blade) – The blade that rests on the middle finger and does not move during the cutting motion
• Tail comb – Used for creating clean, precise sections and partings; the pointed end allows accurate subsectioning
• Razor – Best used on medium to coarse, wet hair; creates soft, tapered ends and movement
- Generally not recommended for very fine or curly hair
Shear Finger Placement
| Finger | Placement |
|---|---|
| Thumb | Thumb ring |
| Ring (3rd) finger | Finger ring |
| Pinky | Finger rest |
| Index & middle fingers | Rest on shank for stability |
Sanitation Requirements (Texas Rules)
• Between every client: Remove all hair/debris, then disinfect with an EPA-registered disinfectant or place in a wet disinfectant solution
• Razor blades: Considered sharps — must be disposed of in a puncture-resistant sharps/biohazard container; never placed loosely in the trash
Key Terms
• Still blade – Stationary blade resting on middle finger
• Thinning shears – Notched blades for bulk removal
• EPA-registered disinfectant – Required for tool sanitation in Texas
• Sharps container – Puncture-resistant biohazard container for used razor blades
⚠️ Watch Out For
• Do not confuse which finger holds the still blade (middle finger) vs. which finger is in the finger ring (ring finger)
• Razor cutting on fine or curly hair is a common wrong answer — the exam may try to trick you into choosing this as a suitable application
• Remember: sanitation between clients is mandatory — skipping this step is a board violation

Sectioning & Parting
Summary
Proper sectioning ensures consistent, controlled results throughout a haircut. The Texas board exam tests your knowledge of standard sections, subsections, and specialized partings like the horseshoe section.
Key Concepts
• Four standard sections of a basic haircut:
1. Front left
2. Front right
3. Back left
4. Back right
- Divided by a center part (forehead to nape) and a horizontal part (ear to ear across the crown)
• Subsection (parting/panel) – A thin slice of hair taken from a larger section; used as a guide for consistent, controlled cutting
• Horseshoe section – A curved parting separating the top of the head from the sides and back; commonly used for cutting layers on top or creating a disconnected design
• Cross-checking – Combing hair in the opposite direction from which it was cut; used to verify that length and weight are even and consistent throughout the haircut
Key Terms
• Subsection – Thin slice used as a guide
• Horseshoe section – Curved parting isolating the crown/top
• Cross-checking – Verification technique using the opposite cutting direction
⚠️ Watch Out For
• Cross-checking is a verification step, not a cutting step — you are checking the work, not re-cutting it
• The horseshoe section is not just for layers — it is also used for disconnected designs

Cutting Techniques
Summary
Elevation angles and guide types are among the most heavily tested concepts on the board exam. You must know how each angle and technique affects weight distribution, silhouette, and texture.
Elevation Angles & Effects
| Elevation | Common Name | Effect |
|---|---|---|
| 0 degrees | Natural fall / No elevation | One-length blunt cut; maximum weight at perimeter |
| 45 degrees | Graduated / Wedge cut | Built-up weight/weight line; triangular silhouette |
| 90 degrees | Uniform layers | Weight evenly distributed; weight line removed |
Guide Types
• Stationary guide – Stays in one place; all sections are brought to it (used in uniform layers)
• Traveling guide – Moves with each new section; previously cut hair becomes the new guide (used in graduated and layered cuts)
Cutting Techniques Defined
• Overdirection – Combing hair away from its natural fall toward a guide before cutting; creates layers because sections farthest from the guide are cut shorter
- Face-framing layers: Hair is overdirected forward/toward the face so front sections fall longer and angle inward
• Point cutting (tip cutting) – Opening and closing shears while pointing tips into the ends of the hair; softens edges, removes bulk, creates texture without a hard line
• Slicing – Shears partially open; one blade is slid along the hair surface; removes length and thins hair while creating soft movement and texture
• Notching – Cutting small triangular pieces into hair ends using shear tips; creates strong texture and separation; typically used on shorter styles
• Freehand cutting – Cutting hair without tension or lifting from natural fall; honors curls and natural texture in their natural state
Key Terms
• Elevation – The angle at which hair is held away from the head before cutting
• Overdirection – Combing hair away from natural fall toward a guide
• Stationary guide – Fixed reference point for cutting
• Traveling guide – Moving reference that shifts with each section
• Point cutting – Shear tips inserted into hair ends for texture
• Slicing – Blade slid along hair surface for movement
• Notching – Triangular cuts into ends for separation
• Freehand cutting – No tension; honors natural curl/texture
⚠️ Watch Out For
• 0 degrees ≠ 90 degrees: 0 degrees creates a weight line; 90 degrees removes it — this is a frequently tested distinction
• Don't confuse slicing (sliding blade along surface) with point cutting (tips inserted into ends)
• Overdirection always shortens the sections farthest from the guide — understanding this concept explains how layers are created

Haircut Design & Shapes
Summary
Recognizing how design elements like weight lines, silhouettes, and disconnection relate to specific haircut styles is essential for the written exam. Expect questions that ask you to identify a haircut based on its description.
Key Concepts
• Weight line – Area of maximum visual weight in a haircut; appears as a visible ridge; results from stacking or graduating hair at a given level
• Bob haircut – One-length or near-one-length cut at chin to shoulder level; features a distinct weight line; ends are blunt or slightly graduated
• A-line / Inverted bob – Variation of the bob where the back is cut shorter (higher) and the front angles longer toward the face; silhouette resembles the letter "A"
• Disconnection – An intentional contrast in length or texture between two areas of the style that are not blended together
Visual Reference: Silhouettes
• Blunt/One-length bob → Straight horizontal weight line, even perimeter
• Graduated/Wedge → Triangular, stacked silhouette
• Uniform layers → Rounded, even silhouette
• A-line bob → Longer in front, shorter in back
Key Terms
• Weight line – Ridge of maximum weight/density
• Disconnection – Intentional unblended contrast between sections
• A-line bob – Shorter back, longer front
• Graduation – Stacking of hair to build weight
⚠️ Watch Out For
• The A-line bob is sometimes called an inverted bob — know both terms
• Disconnection is intentional — it is a design choice, not a mistake or error in blending
• The weight line in a graduated cut sits above the perimeter, not at the very ends

Client Safety & Sanitation
Summary
Texas cosmetology law strictly regulates client safety and sanitation practices. These rules apply at every step of the haircut service and will be tested on both the written and practical board exam.
Key Requirements
#### Draping
• A clean shampoo or cutting cape must be placed over the client's clothing
• A neck strip must be placed between the cape and the client's skin to prevent direct contact
#### Blood/Exposure Incident Protocol
If a client is accidentally cut during a service:
1. Stop the service immediately
2. Put on gloves
3. Clean the wound
4. Apply antiseptic
5. Follow blood exposure procedures
6. Contaminated implements must be properly disinfected or disposed of
#### Palming Shears
• Remove the thumb from the thumb ring
• Place shears in the palm of the cutting hand
• This allows safe use of the comb without risk of cutting the client
#### Razor Blade Disposal
• Razor blades = sharps
• Must go into a puncture-resistant sharps/biohazard container
• Never placed loosely in the trash
Key Terms
• Neck strip – Barrier placed between cape and client's skin
• Cutting cape – Drape used to protect client's clothing
• Palming – Holding shears safely in palm while using comb
• Sharps container – Required disposal for used razor blades
• Blood exposure procedure – Required protocol when skin is broken
⚠️ Watch Out For
• The neck strip is required — a cape alone is not sufficient under Texas rules
• Palming means the thumb is out of the ring — the shears are secured in the palm, not being held actively
• Never put razor blades in regular trash — this is a sanitation and safety violation
