Introduction1:43
Stop turning difficult clients away. Master polygel reconstruction for hooked, curved, and downward-growing nails. Learn to rebuild missing sidewalls, fix cracks, correct over-filed growth points, and transform oval to square. Four real clients with severe deformations — watch complete correction from analysis to finished result. Expand your client base with skills most techs don't have.

Hooked Nail Assessment: Reading Deformation and Planning Correction4:12
Analyze curved and downward-growing nails before reconstruction. Learn where to place base layer when growth points are over-filed, why soft base fails on hooked nails, and how to choose between polygel and gel for different deformation levels.
Polygel Placement on Hooked Nails: Building Sidewalls in the Air8:14
Master the polygel application pattern for severely curved nails. Guide product toward growth points, smooth transitions, rebuild missing corners, and lift dropped tips — all while working fast enough to prevent settling.
Surface Filing After Polygel: Opening the Arch Without Dropping the Lift8:46
Thin from underneath at low RPM to lift curved nails, then surface file at 25,000 RPM. Open the lower arch evenly, check tip thickness before every pass, and prepare the surface for hand filing.
Square Shaping on Reconstructed Nails: Tip, Lower Arch, Sidewalls15:34
Master file positioning for crisp 90-degree corners. Use the file edge as your guide — parallel to table for lower arch, straight up for sidewalls. Learn firm grip technique, even pressure control, and how to protect corners from accidental shaving.
Gel Leveling on Reconstructed Nails: Final Shape and Definition10:28
Apply gel over polygel reconstruction for a refined finish. Create crisp square corners, even sidewalls, and perfect tip thickness. The complete before-and-after transformation.

Long Square Reconstruction: Lifting, Cracks, and Missing Sidewalls6:39
Handle the most intimidating cases — long squares with severe lifting, cracks into living tissue, and twisted sidewalls. Learn crack repair protocol, higher base placement for elevated growth points, and why polygel beats gel for heavy deformation.
Long Square Polygel Placement: Rebuilding Structure on Damaged Nails7:57
Apply polygel on long nails with multiple problems — cracks, missing sidewalls, downward growth. Work two fingers at a time to prevent settling. Learn the brush-in-cleanser trick and how to shape corners before curing.
Long Square Filing: Surface Work and Arch Opening on Length16:30
File long reconstructed squares without losing structure. Match finger lengths, thin from underneath at 15,000 RPM, then surface file at 25,000. Protect corners from bit damage and check tip thickness before every pass.

Shape Transition: Converting Oval to Square with Polygel15:47
Rebuild corners that don't exist. Transform oval shapes into clean squares by adding structure at the growth points, lifting dropped tips from underneath, and filing perfect 90-degree corners. Includes complete polygel workflow.
Oval to Square Finishing: Gel Leveling and Precision Filing8:35
Complete the shape transition with gel overlay. Perfect the square corners, create even sidewalls, and achieve crisp definition. Learn the tip-lower arch-sidewall filing sequence for flawless results.

Polygel Fill on Extensions: Correcting Someone Else's Work6:25
Fix inherited problems — over-filed growth points, missing sidewalls, downward growth. Learn why correction is faster than full removal, how to place polygel high for damaged zones, and the complete fill workflow.
Extension Correction Filing: Lifting the Arch and Refining Shape12:16
File corrected extensions to final form. Thin the tip from underneath first to prevent dropping, open the lower arch evenly, then surface file. Same 90-degree shaping technique — tip, lower arch, sidewalls — with extra care for rebuilt corners.

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
