    Guides students through a timed, complete classic set from prep to finishing. Integrates all prior skills into a cohesive, client-ready service workflow.

  • Lesson 4 • Extension Placement and Direction

    Covers correct attachment point, angle, and directional placement for natural results. Proper placement ensures extensions grow out cleanly without premature shedding.

  • Lesson 5 • Curl and Length Selection

    Explains curl designations, length-to-natural-lash ratios, and weight considerations. Correct selection protects follicle health and achieves the desired aesthetic.

Chapter 4See details

Volume and Mega Volume Techniques

  • Lesson 1 • Volume Set Finishing and Quality Check

    Teaches brushing, fluffing, and quality inspection protocols for completed volume sets. A structured quality check ensures consistency and client satisfaction.

  • Lesson 2 • Diameter and Fan Size Selection
