📖 1. Straight Cut Project

★ Must-know

📌 The project aims to create a clean straight cut with a uniform line while preserving symmetry.

• The selected technique uses a 0° cutting angle, straight scissors and a standing position.

• 🔄 The listed project stages are:

  1. diagnosis
  2. preparation
  3. cutting at 0°
  4. verification

Further detail

• The diagnostic identifies thick, straight, medium-length hair with regular implantation and slight holopage.

• The expected result is a regular straight line, perfect symmetry, controlled volume and harmonized hair.

💡 Memory Hook

A straight, uniform line contrasts with uncontrolled volume.

📖 2. Scissors Parts and Functions

🔑 Key Concepts & Definitions

• Scissors : an extension of the hairdresser’s hand and can cut, thin, equalize, point-cut and graduate hair

★ Must-know

📌 The scissors are divided into a gripping section and an active section.

Further detail

• The named parts include the points, plane, screw, branch, tang, cutting edge, heel, blade, notch, rings, stop and reducing ring.

💡 Memory Hook

Picture the scissors divided into a hand-grip section and an active cutting section.

📖 3. Holding and Handling Scissors

★ Must-know

• 🔄 To hold the scissors: insert the first phalanx of the thumb into the lower ring, insert the first phalanx of the ring finger into the upper ring, rest the little finger on the tang, place the index and middle fingers on the upper branch

• 🔄 During cutting:

  1. keep the screw facing the operator
  2. keep the scissors parallel to the fingers
  3. move the upper blade with the thumb

Further detail

📌 The cutting rhythm must remain regular to produce a regular result and avoid lines in the hair.

📌 The comb is held in the same hand as the scissors, and after cutting the thumb is removed and the scissors are closed in the hand for safety.

💡 Memory Hook

Thumb and ring finger in the rings, little finger on the tang, index and middle fingers on the upper branch.

📖 4. Hand Positions for Cutting

★ Must-know

📌 For full cuts such as fringes, bobs and equalizations, the palm faces downward and the fingers are under the blades.

📌 For graduated cuts on the crown, the hand is elevated and the hair is cut along and above the fingers.

Further detail

📌 For other areas of the head, the palms face each other during cutting.

• Different cutting techniques and scissors can lighten, texturize, design or add body to the hair.

💡 Memory Hook

Palm down supports full cuts, raised hands shape graduation, and palm-to-palm serves other zones.

📖 5. Scissors Care and Safety

🔑 Key Concepts & Definitions

• Sharpening : the delicate operation of restoring the edge to a blunt or chipped blade, and it is entrusted to a specialist

★ Must-know

• After use, the scissors should be wiped, regularly oiled at the notch, disinfected with spray or wipes, sterilized with ultraviolet rays and stored carefully in their case.

📌 Scissors must be kept sharp to ensure a clean cut and prevent pulling the client’s hair.

Further detail

📌 Regularly oiling the notch ensures cutting precision and reduces hand muscle fatigue associated with musculoskeletal disorders.

📌 For safety, scissors should not be dropped, placed in pockets or used for purposes other than cutting hair, and they should be kept away from children.

💡 Memory Hook

Cleaning, oiling, sharpening and safe storage preserve precision and protect the client.

📖 6. Scissors Sizes and Uses

★ Must-know

• Scissors are generally sized in inches, with common sizes ranging from 4.5 to 7 inches.

📌 The blade length should not exceed the length of the middle finger, while the total scissor length should be approximately equal to the total length of the hand.

Further detail

📌 Scissors measuring 6.5 to 7 inches are used to rough-cut hair and perform intensive, massive cuts.

📌 Scissors measuring 6.5 to 5.5 inches are used for classic graduations, bobs and thinning cuts.

• Scissors measuring 5 to 4.5 inches are used for precise and structured cuts.

💡 Memory Hook

Large scissors handle massive work, medium scissors shape classic cuts, and small scissors make precise cuts.
