Perform Nail Extension and Overlay Services
Core Concepts
Nail extensions add length and shape; overlays strengthen natural nails. Common types: acrylic (liquid and powder), gel, silk/fiberglass wrap, and dip powder. Each has specific application steps: prep (sanitize, push cuticles, buff nail plate) → apply tip or form (for extensions) → apply product → shape and refine → finish (buff, polish, seal).
Key Terms and Safety
- Nail plate preparation: Remove shine, dehydrate with primer (for acrylic), and ensure nail is clean and dry. Improper prep causes lifting.
- Ratio (acrylic): Correct liquid-to-powder ratio is crucial; too wet causes shrinkage, too dry causes brittle nails.
- Curing (gel): Use UV/LED lamp according to manufacturer’s instructions; under-curing leads to service breakdown and allergic reactions.
- E-file safety: Use proper bits, light pressure, and never drill on a natural nail plate excessively. Keep the e-file moving to avoid burns.
- Contraindications: Do not apply extensions on infected, inflamed, or damaged nails; refer to a doctor.
Traps
- Skipping nail plate prep → lifting.
- Wrong acrylic ratio → weak or brittle enhancements.
- Over-filing natural nail → thinning and damage.
- Using dirty tools or not disinfecting e-file bits.
- Applying product on infected nails.
Worked Example / Rule of Thumb
Rule: “Prep, prime, apply, shape, finish.” For acrylic: sanitize, push cuticles, buff, dehydrate, apply primer, attach tip/form, apply acrylic with correct ratio, shape, buff, and seal. Always check for contraindications first.
Exam Tip
Questions often test prep steps, acrylic ratio, e-file safety, and contraindications. Remember: never apply extensions on infected nails; proper prep prevents lifting.
