Course Curriculum
12 lessons across 4 real cases · hooked nails · crack repair · shape transformation · extension correction
Case 1 — Curved & Hooked Nails
1
Reading the Disaster: What I Look for Before Touching a Problem Nail
Assessment checklist before picking up any tool. Where's the growth point? How severe is the hook? Is it growing down, twisting sideways, or both? This determines everything that comes after.
Assessment
2
Building Sidewalls in the Air: Polygel on Nails with Nothing to Hold Onto
When the natural sidewall is gone — over-filed, twisted, or just never there. How to guide polygel toward growth points, create structure where there's nothing, and lift tips that point at the floor.
Polygel Placement
3
How to File Reconstructed Nails Without Undoing the Correction
The sequence that protects your work: thin from underneath first at low RPM, then surface file at high RPM, then shape. Check tip thickness constantly.
Filing
4
Square Corners on Nails That Never Had Corners
The e-file gets you close. The hand file gets you perfect. Grip, pressure, and the trick of using your file edge as a visual guide. Tip first, then lower arch, then sidewalls.
Hand Filing
5
The Final Layer: Gel Over Polygel for a Finished Look
Polygel alone looks matte and rough. Gel over top gives you shine and refinement — but the layer has to be thin or you lose the shape you just created.
Gel Finish
Case 2 — Long Square with Cracks
6
Cracks Into Living Tissue: When to Cut, When to Seal, When to Wait
Not all cracks are the same. Surface splits can be sealed today. Cracks into the nail bed need to grow out. How to assess crack severity and choose your approach.
Crack Assessment
7
Long Square Reconstruction: Lifting, Cracks, and Twisted Sidewalls All at Once
Crack repair protocol, higher base placement for elevated growth points, and why polygel wins over gel when deformation is this bad.
Repair & Rebuild
8
Filing Long Reconstructed Nails Without Losing the Structure You Built
Long nails flex more. How to match finger lengths, thin from underneath without weakening, and surface file without heat or vibration.
Long Nail Filing
Case 3 — Oval to Square Transformation
9
She Wants Squares But Has Ovals: Creating Corners That Don't Exist
Polygel at the growth points, shape before curing, then file the square in. How to decide where the new corner should be and how to create structure to support it.
Building Corners
10
From Round to Sharp: Filing the Transformation Complete
Gel overlay for refinement, then precise filing: tip, lower arch, sidewalls. The client came in with soft ovals and leaves with crisp squares.
Final Shaping
Case 4 — Inherited Extension Corrections
11
Inherited Extensions: Why Correction Beats Full Removal
Assessment, fill workflow, and how to fix problems without adding more. Correction is faster and less damaging than starting over.
Extension Fix
12
Filing Corrected Extensions: Same Rules, Extra Caution
Thin the tip from underneath first to prevent dropping. Open the lower arch evenly. Protect rebuilt corners. Same technique as natural nails, just more patience.

Problem nails have patterns. This map gives you a decision tree for the most common failures — find the root cause fast, apply the smallest fix that makes the biggest difference. Use it at your station before every difficult appointment.
- Hooked and curved nails — growth point assessment before you pick up any tool
- Lifting mapped by zone — separate logic for cuticle area, sidewalls, and free edge
- Crack assessment: surface split vs nail bed — when to seal, when to wait
- Shape transformation logic and inherited extension decision trees

Verified reviews from nail techs who completed the courses
This Diagnosis map is a practical troubleshooting tool for nail techs. It helps you identify the most likely cause of common failures and apply a First Fix (the smallest change with the biggest impact).

Frequently Asked Questions
Is this course suitable for beginners?
No. This is genuinely advanced work. The course assumes you are already confident with gel leveling, e-file removal, and shape filing. If you haven't done the Oval or Square course, start there first.
What is polygel and why is it used for problem nails?
Polygel is a hybrid product — thicker than gel, more workable than acrylic. It holds shape where regular gel collapses. For hooked, curved, or structurally compromised nails, polygel can be shaped before curing, which means you can guide it toward growth points and build structure in mid-air.
Can hooked nails be permanently corrected?
The nail grows the way the matrix tells it to — that doesn't change. What you can do is correct the appearance and structure at every appointment. With proper reconstruction at each fill, the nail gradually improves. Some clients see significant long-term improvement; others need maintenance at every visit.
How do I know if a crack can be sealed or needs to grow out?
Surface splits above the stress point can usually be sealed today. Cracks that reach into or near the nail bed need to grow out — sealing them can trap bacteria. Lesson 6 covers the assessment in detail.
Why is correction better than removing inherited extensions?
Full removal damages the nail plate and takes more time. If extensions are structurally intact, correction is faster and less traumatic. Lessons 11 and 12 show the full workflow.
How long do these appointments take?
Longer — don't promise 50 minutes. A hooked nail reconstruction first appointment can take 90 minutes or more. This is premium-priced work, and clients who need it understand the time investment.
Is a certificate included?
Yes. A certificate of completion from VEL Academy is issued automatically after you finish all modules.
