  • Lesson 2 • Industry Standards and Regulations

    Introduces professional licensing requirements, health codes, and cosmetic safety regulations. Ensures students understand the compliance framework before touching a client.

    Covers orbital structure, eyelid layers, and natural lash growth cycle. Provides the anatomical baseline needed to make safe product and technique decisions.

  • Lesson 4 • Professional Ethics and Client Rights

    Defines informed consent, confidentiality, and ethical conduct standards. Builds the professional mindset that underpins every client interaction throughout the course.

Chapter 2See details

Tools, Products, and Workspace Setup

  • Lesson 1 • Adhesives and Bonding Chemistry

    Explains cyanoacrylate chemistry, cure time, and humidity sensitivity. Students learn to choose and store adhesives correctly to ensure bond strength and safety.

  • Lesson 2 • Ergonomic Workspace Configuration

    Covers bed height, lighting, magnification, and technician posture. An ergonomic setup reduces injury risk and sustains precision across long service sessions.

  • Lesson 3 • Lash Extension Types and Materials

    Compares synthetic, silk, and mink-style fibres by curl, thickness, and length. Gives students the product knowledge to match extensions to client needs.

  • Lesson 4 • Tools and Their Correct Use

    Introduces tweezers, micro-brushes, jade stones, and tape types with correct grip and handling. Proper tool use prevents damage to natural lashes and improves precision.

Chapter 3See details

Client Consultation and Assessment

  • Lesson 1 • Eye Shape and Facial Analysis

    Analyses eye shapes, lid types, and facial proportions to guide extension mapping. Connects anatomical assessment directly to style and length recommendations.

  • Lesson 2 • Contraindications and Referral Protocol

    Identifies conditions requiring service refusal or medical referral, including infections and severe allergies. Protects clients and limits technician liability.

  • Lesson 3 • Intake Forms and Health Screening

    Teaches design and use of health history forms to screen for allergies and contraindications. Accurate intake data protects clients and creates a legal record of consent.

  • Lesson 4 • Style Selection and Client Communication

    Guides students through translating client lifestyle and preferences into a lash map. Effective communication prevents mismatched expectations and repeat corrections.

Classic Lash Application Techniques

  • Lesson 1 • Adhesive Application and Bonding

    Covers correct adhesive dot size, dipping angle, and placement on the natural lash. Consistent bonding technique directly determines set longevity and client safety.

  • Lesson 2 • Classic Set Troubleshooting

    Diagnoses and corrects stickies, poor retention, and uneven placement during and after application. Builds the self-correction skills needed for consistent professional results.

  • Lesson 3 • Full Classic Set Execution

    Integrates isolation, mapping, and bonding into a timed full-set application on a mannequin and live model. Students meet retention, symmetry, and timing benchmarks.

  • Lesson 4 • Lash Mapping and Design Planning

    Teaches creating a lash map on eye pads before application to guide length and curl placement. A precise map ensures symmetry and reduces mid-service corrections.

  • Lesson 5 • Isolation Technique

    Develops the skill of isolating a single natural lash with a non-dominant hand tweezer. Proper isolation is the single most critical factor in retention and lash health.

Chapter 5See details

Volume and Mega Volume Techniques

  • Lesson 1 • Volume Lash Fundamentals

    Explains the weight-per-natural-lash rule and how volume differs structurally from classic. Establishes the safety logic that governs all fan construction decisions.

  • Lesson 2 • Pre-Made and Promade Fan Application

    Covers selection, adhesive loading, and placement of pre-made fans for speed-focused services. Students learn when pre-mades are appropriate and how to maintain quality.

  • Lesson 3 • Handmade Fan Construction

    Teaches pinching, rolling, and bouquet methods for creating 2D–6D fans from a strip. Handmade fans allow customisation of width and density not possible with pre-mades.

  • Lesson 4 • Volume Set Quality Assessment

    Evaluates completed volume sets against retention, uniformity, and weight compliance standards. Develops the critical eye needed for consistent professional-grade output.

  • Lesson 5 • Mega Volume Application

    Applies 8D–16D ultra-fine fans using advanced isolation and precise adhesive control. Requires mastery of all prior fan skills and strict weight compliance.

Lash Fills, Removal, and Maintenance

  • Lesson 1 • Fill Appointment Assessment

    Teaches evaluating grown-out sets for retention percentage, lash health, and style consistency. Accurate assessment determines fill strategy and time allocation.

    Demonstrates gel and cream remover application, dwell time, and gentle sliding technique. Incorrect removal is the leading cause of natural lash damage and must be mastered.

  • Lesson 3 • Fill Execution Techniques

    Covers removal of grown-out extensions, isolation of new growth, and seamless style blending. Efficient fill technique maintains set appearance between full appointments.

  • Lesson 4 • Lash Health Monitoring Over Time

    Tracks natural lash condition across multiple appointments to detect overextension or damage. Proactive monitoring prevents long-term client lash loss and builds trust.
