Lash Extension Materials and Adhesives

  • Lesson 1 • Adhesive Storage and Troubleshooting

    Covers proper storage conditions, expiration indicators, and common adhesive failures. Correct storage preserves adhesive performance and client safety.

  • Lesson 2 • Extension Fiber Characteristics

    Examines synthetic, mink-style, and silk-style fibers for weight, sheen, and durability. Material choice directly affects client comfort and retention.

  • Lesson 3 • Adhesive Chemistry and Curing

    Explains cyanoacrylate chemistry, humidity sensitivity, and curing stages. Understanding adhesive behavior prevents poor retention and adverse reactions.

  • Lesson 4 • Adhesive Application Techniques

    Teaches correct bead size, dipping angle, and placement speed for optimal bonds. Consistent application technique is the single greatest factor in retention.

  • Lesson 5 • Curl Types and Length Charts

    Maps curl designations from J to D and length ranges from 6 mm to 20 mm. Accurate curl and length selection shapes the final design outcome.

Chapter 3See details

Eye Shape Analysis and Design Mapping

  • Lesson 1 • Identifying Eye Shapes

    Classifies almond, round, hooded, monolid, downturned, and wide-set eye shapes. Accurate classification is the prerequisite for all design decisions.

  • Lesson 2 • Design Styles and Their Effects

    Covers natural, cat-eye, doll-eye, squirrel, and staggered styles. Each style creates a distinct visual effect suited to specific eye shapes.

  • Lesson 3 • Lash Mapping Principles

    Introduces zone-based lash mapping and length-placement logic. A precise map translates design intent into consistent, repeatable application.

  • Lesson 4 • Client Consultation and Design Selection

    Teaches structured consultation questions, lifestyle assessment, and design recommendation. Matching design to client lifestyle increases satisfaction and retention.

  • Lesson 5 • Adapting Designs for Unique Features

    Addresses ptosis, sparse lashes, mature clients, and corrective mapping strategies. Adaptive design skills expand the technician's client base significantly.

Chapter 4See details

Classic Lash Application Fundamentals

  • Lesson 1 • Isolation Technique

    Teaches single-lash isolation using the non-dominant hand tweezer. Isolation prevents bonding multiple lashes together, which causes damage and discomfort.

  • Lesson 2 • Classic Extension Placement

    Demonstrates correct attachment point, angle, and wrap for one-to-one placement. Precise placement ensures natural movement and long-term lash health.

  • Lesson 3 • Completing and Finishing a Classic Set

    Guides students through full-set sequencing, gap filling, and final inspection. A systematic finish ensures even coverage and a polished client result.

  • Lesson 4 • Workstation Setup and Client Positioning

  • Lesson 5 • Eye Preparation and Taping

    Covers under-eye pad placement, taping lower lashes, and priming natural lashes. Correct preparation isolates the work area and improves adhesive bonding.

Chapter 5See details

Volume Lash Techniques

  • Lesson 1 • Premade and Promade Fan Use

    Compares handmade fans with premade and promade options for speed and consistency. Understanding trade-offs helps technicians choose the right approach per service.

  • Lesson 2 • Volume Lash Theory and Safety

    Explains weight-to-natural-lash ratios and safe fan diameter limits. Volume theory prevents overloading lashes and causing premature shedding.

  • Lesson 3 • Handmade Fan Construction

    Teaches pinching, rolling, and bouquet methods for creating symmetrical fans. Consistent fan shape is the foundation of a polished volume set.

  • Lesson 4 • Completing a Full Volume Set

    Guides sequencing, density balancing, and finishing steps for a complete volume set. Systematic completion produces even fullness and a professional result.

  • Lesson 5 • Volume Application and Placement

    Applies fan placement rules for base width, angle, and wrap on natural lashes. Correct placement ensures fan stability and prevents premature fan closure.

Chapter 6See details

Mega Volume and Hybrid Techniques

  • Lesson 1 • Hybrid Application Workflow

    Sequences classic and volume placements within a single hybrid service efficiently. A structured workflow prevents adhesive drying delays and ensures even coverage.

  • Lesson 2 • Mega Volume Application Rules

    Covers weight limits, isolation demands, and placement precision for mega volume. Strict adherence to weight rules protects natural lash integrity at high density.

  • Lesson 3 • Troubleshooting Advanced Sets

    Addresses fan closure, stickies, poor retention, and uneven density in advanced sets. Systematic troubleshooting skills reduce rework time and improve client outcomes.

  • Lesson 4 • Hybrid Set Design and Mapping

    Defines hybrid sets as a blend of classic and volume extensions in a single design. Strategic placement of each type creates texture and dimension unique to hybrid work.

  • Lesson 5 • Mega Volume Fan Construction

    Extends fan-building skills to ultra-fine 0.03–0.05 mm fibers for 7D–16D fans. Mastery of ultra-fine fibers enables dramatic, lightweight mega volume results.
