Natural Nail Care and Preparation

  • Lesson 1 • Pedicure Service Fundamentals

    Adapts manicure skills to foot care, including callus reduction and toenail shaping. Students learn safe foot hygiene practices and client comfort positioning.

  • Lesson 2 • Classic Manicure Service Sequence

    Guides students through a timed, step-by-step manicure protocol from soak to finish. Mastering this sequence builds the procedural discipline applied in all subsequent services.

  • Lesson 3 • Cuticle Care and Skin Preparation

    Covers safe cuticle softening, removal, and skin conditioning methods. Thorough preparation maximizes product adhesion and minimizes lifting.

  • Lesson 4 • Nail Shaping Techniques

    Teaches the five primary nail shapes and the filing mechanics required for each. Correct shaping prevents stress fractures and sets the foundation for enhancement adhesion.

  • Lesson 5 • Nail Surface Assessment and Dehydration

    Teaches technicians to evaluate nail plate condition and apply dehydrators and primers correctly. Accurate assessment prevents product failure before any enhancement is applied.

Nail Polish and Lacquer Application

  • Lesson 1 • Nail Art with Polish

    Introduces freehand nail art, stamping, and striping tape techniques using standard lacquer. These skills expand service offerings and increase client retention.

  • Lesson 2 • Lacquer Application Technique

    Develops brush control, stroke sequence, and thin-coat discipline for flawless coverage. Consistent technique eliminates streaks, bubbles, and flooding of the cuticle area.

  • Lesson 3 • Base Coat and Top Coat Science

    Explains the chemistry and function of base coats, top coats, and ridge fillers. Correct layering extends wear time and protects both the natural nail and the color coat.

  • Lesson 4 • Color Theory for Nail Services

    Applies color wheel principles to nail polish selection and client skin tone matching. Understanding undertones and contrast guides technicians toward flattering, sellable color choices.

Chapter 4See details

Gel Polish Systems

  • Lesson 1 • Gel Polish Nail Art Techniques

    Adapts stamping, foils, and gel paint to create durable nail art within the gel system. Curing between layers ensures structural integrity of complex designs.

  • Lesson 2 • Gel Polish Chemistry and Curing

    Explains photoinitiators, oligomers, and the polymerization process triggered by UV/LED lamps. Understanding curing science prevents under-cure, inhibition layers, and heat spikes.

  • Lesson 3 • Troubleshooting Gel Polish Issues

    Diagnoses and corrects lifting, peeling, bubbling, and color fading in gel services. Systematic troubleshooting reduces product waste and client callbacks.

  • Lesson 4 • Safe Gel Polish Removal

    Teaches acetone soak-off, foil wrapping, and gentle plate restoration after removal. Improper removal is the leading cause of nail plate thinning and client dissatisfaction.

  • Lesson 5 • Gel Polish Application Protocol

Acrylic Nail Enhancement Systems

  • Lesson 1 • Acrylic Chemistry and Monomer Safety

    Explains the polymerization of monomer and polymer and the associated chemical hazards. Safe handling practices and MMA awareness are mandatory before any product contact.

  • Lesson 2 • Bead Consistency and Ratio Control

    Trains students to pick up and place wet, medium, and dry beads with correct liquid-to-powder ratios. Consistent bead consistency is the single greatest predictor of enhancement durability.

  • Lesson 3 • Acrylic Overlay and Sculpting

    Teaches full overlay on natural nails and free-edge sculpting using forms. Correct apex placement and zone distribution ensure structural strength and natural appearance.

  • Lesson 4 • Filing, Buffing, and Surface Finishing

    Develops the filing sequence that refines shape, removes surface imperfections, and prepares for polish or gel top coat. Proper grit progression prevents heat damage and over-thinning.

  • Lesson 5 • Tip Application and Blending

    Covers nail tip sizing, adhesive application, and seamless blending into the natural nail. A well-blended tip creates an invisible foundation for the acrylic overlay.

Chapter 6See details
