Problem Nails Masterclass: Hooked, Curved & Downward-Growing Nail Correction
What you'll learn
Correct hooked, curved, and downward-growing nails using polygel reconstruction techniques
Rebuild missing sidewalls and corners "in the air" when natural structure is gone
Repair cracks in natural nails — both free edge cuts and deep splits into living tissue
Transform oval shapes to perfect squares by adding polygel structure at growth points
Place base layer correctly on over-filed and elevated growth points to prevent lifting
Choose between polygel and gel based on deformation severity and time efficiency
Handle inherited work: fills and corrections on extensions with multiple problems
Requirements
Complete the Oval Shape or Square Shape course first — this is an advanced course that builds on those fundamentals
Experience with gel leveling technique (covered in Oval or Square shape courses)
Access to polygel products, e-file with carbide bits, and standard manicure tools
Confidence working with e-file at various RPM settings (10,000–25,000)
Description
This course contains the use of artificial intelligence.
Stop turning difficult clients away. This advanced course teaches polygel reconstruction for the most challenging nail conditions — hooked nails, curved nails, downward-growing nails, and severely damaged extensions.
You'll work through four real client cases with significant deformations. Each case demonstrates complete correction from initial assessment to finished result, so you see exactly how to handle problems that make other technicians refuse the appointment.
WHAT YOU'LL LEARN
Polygel reconstruction techniques for nails that grow downward, twist sideways, or hook at the free edge. You'll master building sidewalls "in the air" when natural structure is completely gone, and learn to lift dropped tips without creating bulk.
Crack repair protocols for both free edge damage and deep splits into living tissue. Understand when to cut out damage versus seal and reinforce.
Shape transformations — converting oval to square by rebuilding corners that don't exist. Add structure at growth points and file perfect 90-degree corners on nails that never had them.
Extension corrections for inherited problems. Fix over-filed growth points, rebuild missing sidewalls, and correct someone else's mistakes faster than full removal.
COURSE STRUCTURE
Each module follows the complete workflow: analysis, base layer placement, polygel application, surface filing with bit, hand filing for shape, and gel overlay for finish. Right-hand demonstrations include timing benchmarks so you can measure your progress.
This course requires completion of Oval or Square Shape fundamentals. Recommended for nail technicians ready to expand beyond standard services into reconstruction work that builds reputation and client loyalty.
Who this course is for
Nail technicians who want to stop turning away clients with difficult nail conditions
Professionals ready to expand services beyond standard manicures to complex corrections
Techs who inherited clients with hooked, curved, or poorly maintained extensions
Anyone who wants to build reputation through word-of-mouth from grateful "problem nail" clients
Experienced manicurists looking to master polygel as a reconstruction material
