8 Chapters • 40 LessonsDuration between 4 and 360 hours (you decide)

Chapter 1See details

Foundations of Eyelash Extension

  • Lesson 1 • Tools and Materials Overview

    Introduces tweezers, adhesives, lash trays, and eye pads. Familiarity with each tool's purpose prepares students for hands-on practice sessions.

  • Lesson 2 • Client Consultation Fundamentals

    Covers intake forms, contraindication screening, and expectation setting. Effective consultation reduces adverse events and builds client trust.

  • Lesson 3 • Industry Standards and Regulations

    Introduces professional licensing requirements, health codes, and scope of practice. Students understand compliance obligations before touching any client.

  • Lesson 4 • Eye and Lash Anatomy

    Covers orbital anatomy, lash growth cycles, and follicle structure. This knowledge underpins safe placement and retention decisions throughout the course.

  • Lesson 5 • Sanitation and Hygiene Protocols

    Teaches disinfection, sterilization, and single-use tool policies. Proper hygiene prevents infection and protects both client and technician.

Chapter 2See details

Lash Extension Materials and Selection

  • Lesson 1 • Curl Patterns and Their Applications

    Examines J, B, C, CC, D, and L curl designations and their visual effects. Matching curl to eye shape is essential for flattering results.

  • Lesson 2 • Adhesive Science and Selection

    Covers cyanoacrylate chemistry, cure times, humidity sensitivity, and retention factors. Adhesive mastery is critical for safe, long-lasting bonds.

  • Lesson 3 • Extension Fibre Types and Properties

    Compares synthetic, silk, and mink-style fibres by weight, sheen, and durability. Material choice directly affects client comfort and retention.

  • Lesson 4 • Primers, Sealers, and Aftercare Products

    Explains how primers remove oils, sealers protect bonds, and aftercare products extend retention. Students learn when and how to apply each product.

  • Lesson 5 • Length and Diameter Guidelines

    Establishes safe length-to-natural-lash ratios and diameter matching rules. Overloading natural lashes causes premature shedding and damage.

Chapter 3See details

Core Application Techniques

  • Lesson 1 • Classic Full-Set Application Sequence

    Introduces the outer-to-inner application order and symmetry checking methods. A structured sequence ensures even coverage and balanced results.

  • Lesson 2 • Isolation Technique Mastery

    Teaches single-lash isolation using the non-dominant hand tweezer. Clean isolation prevents bonding adjacent lashes, which causes pain and damage.

  • Lesson 3 • Adhesive Dipping and Placement

    Covers correct dip depth, bead size, and placement angle on the natural lash. Consistent adhesive application is the foundation of retention.

  • Lesson 4 • Workstation Setup and Ergonomics

    Establishes proper bed height, lighting, and posture to prevent technician fatigue. A consistent setup improves precision and reduces repetitive strain.

  • Lesson 5 • Curing and Finishing Procedures

    Explains nano-mist curing, adhesive off-gassing, and safe eye-opening protocols. Proper finishing prevents irritation and locks in retention.

Chapter 4See details

Eye Shape Analysis and Mapping

  • Lesson 1 • Lash Mapping Principles

    Teaches zone-based mapping using eye pads and markers to plan length placement. A precise map guides consistent application across the full lash line.

  • Lesson 2 • Designing Signature Lash Looks

    Combines shape analysis and mapping to create natural, cat-eye, doll-eye, and wispy styles. Students produce a portfolio of mapped designs for each look.

  • Lesson 3 • Identifying Eye Shape Categories

    Covers almond, round, hooded, monolid, downturned, and upturned eye classifications. Accurate identification is the prerequisite for all design decisions.

  • Lesson 4 • Face Shape and Feature Harmony

    Examines how face shape, brow arch, and nose bridge influence lash design choices. Lash maps must complement the full face, not just the eye.

  • Lesson 5 • Corrective Design Strategies

    Applies mapping to visually lift, open, elongate, or balance specific eye concerns. Corrective design adds professional value and client satisfaction.

Chapter 5See details

Adverse Reactions and Risk Management

  • Lesson 1 • Contraindication Management

    Reviews absolute and relative contraindications including chemotherapy, alopecia, and active infections. Refusing service when indicated protects both parties.

  • Lesson 2 • Recognising Adverse Reactions

    Distinguishes irritant contact dermatitis, allergic contact dermatitis, and chemical burns by symptom profile. Early recognition enables faster, safer responses.

  • Lesson 3 • Emergency Response Procedures

    Prepares students to manage eye irrigation, product-in-eye incidents, and anaphylaxis first steps. Knowing when to refer to medical care is equally critical.

  • Lesson 4 • Risk Reduction and Documentation

    Establishes informed consent, service records, and incident reporting as risk management tools. Thorough documentation is the technician's primary legal protection.

  • Lesson 5 • Patch Testing Protocols

    Covers adhesive and product patch test procedures, timing, and result interpretation. Patch testing is the primary prevention tool for allergic reactions.

Chapter 6See details

Volume and Mega Volume Techniques

  • Lesson 1 • Premade and Promade Fan Application

    Covers selection, adhesive loading, and placement of premade and promade fans. These options increase speed while maintaining a full, fluffy result.

  • Lesson 2 • Volume Set Application Workflow

    Applies volume fans across a full set using zone-based sequencing and symmetry checks. Workflow efficiency is essential for managing longer appointment times.

  • Lesson 3 • Mega Volume and Texture Techniques

    Introduces 8D to 20D fans, spiky textures, and wet looks for editorial and dramatic styles. Advanced fan construction requires refined pinching and speed.

  • Lesson 4 • Volume Lash Fundamentals

    Explains the difference between classic, volume, and mega volume in terms of fan count and lash weight. Understanding load limits prevents natural lash damage.

  • Lesson 5 • Handmade Fan Construction

    Teaches pinching, rolling, and bouquet methods for creating 2D to 6D fans. Consistent fan shape and base size are critical for retention and appearance.

Chapter 7See details

Lash Fill and Maintenance Services

  • Lesson 1 • Retention Assessment and Analysis

    Teaches percentage-based retention evaluation and root cause identification. Accurate assessment determines whether a fill or full removal is needed.

  • Lesson 2 • Fill Application Strategy

    Explains how to blend new extensions with existing ones for seamless density. Fill strategy varies by retention level and style maintenance goals.

  • Lesson 3 • Client Retention and Rebooking

    Connects fill quality to client loyalty and rebooking rates. Students learn to communicate maintenance schedules and aftercare to maximize retention.

  • Lesson 4 • Safe Extension Removal Techniques

    Covers gel and cream remover application, dwell times, and safe sliding removal. Improper removal is a leading cause of natural lash damage.

  • Lesson 5 • Natural Lash Health Monitoring

    Identifies signs of traction stress, breakage, and follicle fatigue across appointments. Monitoring protects long-term client lash health and retention.
