PAGE 3 How to use this map (60 seconds)
Symptom → Cause → First Fix
1) Name the symptom Example: “lifting on sidewalls” or “hooked nails”.
2) Check the top 3 causes Follow the order (most common → less common).
3) Apply the First Fix Small change first. Retest. Then adjust further if needed.
Rule of thumb: if you change everything at once (prep, material, shape, thickness), you won’t know what actually solved the problem.
Start with the First Fix and keep the rest stable.

PAGE 5 The 5 non-negotiables (brand doesn’t fix these)
High-impact fundamentals
Prep sequence order: if order is wrong, adhesion suffers even with “perfect” products.Contact points & thickness logic: strength comes from architecture, not bulk.Shape architecture: apex position + sidewall thickness decide wear and breakage.Correction vs extension logic: some nails require correction; “standard” building won’t hold.Age-related changes: mature hands require different control and finish decisions. Use this guide like a checklist. When a set fails, start from the non-negotiables. Then apply the decision trees.

Your starting point
Symptom What it usually means Go to Lifting (cuticle / sidewalls / free edge)Adhesion breakdown due to prep, placement, structure, or stress points. Page 7 Breakage / cracks Architecture mismatch: apex, sidewall thickness, shape choice, or correction need. Page 10 Hooked / curved nails (“diving down”)Requires correction logic and a different building approach. Page 11 Shape issues (square vs oval)Wrong shape for the client’s nail/hand dynamics, or incorrect filing logic. Page 12 Bulky / uneven profile Placement, leveling, apex position, and sidewall thickness control. Page 13 Restoration vs strengthening Choosing the wrong workflow creates repeat failures. Page 14 Oval → Square transition Transition without structure control creates asymmetry and stress points. Page 14 Stamping fails Surface prep + technique mechanics (pressure/angle/speed).

PAGE 7 Decision Tree 1 — Lifting (by zone)
Find the zone → apply First Fix
Pick the zone where lifting starts first. Then follow the causes in order. Apply the First Fix before changing products.
1) Lifting at the cuticle area Top causes (in order)
1) Cuticle "film" left on the plate
First Fix
Re-check cuticle area cleaning under light. Keep product placement controlled with a safe margin and correct leveling.
Don’t do
Don’t “fix” this with stronger primer first. If the film remains or placement floods, adhesion will still fail.
Next step in the full training: Gel workflows (prep + placement + finish).
PAGE 8 Decision Tree 1 — Lifting (by zone), continued
Find the zone → apply First Fix
2) Lifting on the sidewalls Top causes (in order)
1) Sidewalls built too thick (stress point)
First Fix
Check sidewall thickness from top + side view. Reduce bulk while keeping strength in the correct zone (architecture).
Don’t do
Don’t over-thin the free edge to compensate — it moves the stress point and can cause breakage.
Next step in the full training: Square/Oval shaping logic & structure.
PAGE 9 Decision Tree 1 — Lifting (by zone), continued
Find the zone → apply First Fix
3) Lifting at the free edge Top causes (in order)
1) Stress point not supported by structure
First Fix
Check architecture (apex position) and free-edge thickness consistency. Confirm finishing steps support wear.
Don’t do
Don’t just “add more product” at the tip without a structural plan — it becomes bulk, not strength.
Next step in the full training: Strengthening & restoration workflows.
PAGE 10 Decision Tree 2 — Breakage / cracks
Architecture first
Most breakage is architecture. Diagnose where the crack starts, then choose the workflow.
Where does the nail break most often? Free edge / corners: often shape choice + edge thickness + stress point.Middle / apex area: often apex position mismatch or over-filing.Sidewalls: often sidewall bulk or asymmetry creating torque. Top causes (in order)
1) Stress point unsupported by structure
First Fix
Use the “minimum strength” rule: add strength only where load is. Keep everything else thin and clean.
When to switch material
Switch only after architecture is correct. Material can’t compensate for wrong structure.
Next step in the full training: Express restoration & gel strengthening. For corrections/long wear: Polygel workflows.
PAGE 11 Decision Tree 3 — Hooked / curved nails (“diving down”)
Correction logic
Hooked / curved nails are a correction case . Standard building can make them look thicker and still not hold.
Quick diagnosis Does the natural nail tip point downward? After removal, do nails look uneven in length and shape? Does the free edge “hook” more over time? Top causes (in order)
1) Natural shape needs correction plan
First Fix
Stop treating it as a “standard nail”. Plan correction and build structure that neutralizes the downward tip.
Don’t do
Don’t thin the tip aggressively to “make it look straight” — it will bend more and break.
Next step in the full training: Hooked/Curved Nails correction workflow.
PAGE 12 Decision Tree 4 — Shape choice: Square vs Oval
Choose shape to reduce failures
Shape is not aesthetic only — it is load distribution. Wrong shape can create repeating lifting/breakage.
When square often fails Thin/flexible natural nails + long wear High daily load (typing, cleaning, lifting objects) Sharp corners catching → micro-cracks First Fix: soften corners and review sidewall thickness. Consider oval for durability when the client’s lifestyle is high-load.
Next step in the full training: Square Shape Nails (structure + filing).
When oval is the smarter choice Clients who want durability with minimal thickness When corners repeatedly lift or break When you need a cleaner, lighter profile First Fix: use oval as a durability strategy, then build clean structure rather than adding bulk.
Next step in the full training: Oval Shape Nails.
PAGE 13 Decision Tree 5 — Bulky structure / uneven profile
Placement & control
“Bulky” is usually not about product amount — it’s about where the thickness sits and how the profile reads in light.
Quick checks (60 seconds) Side view: is the apex in the correct position or too close to cuticle / too far forward?Top view: are sidewalls thicker than necessary?Light reflection: does the highlight line break (waves)? That’s uneven leveling. Top causes (in order)
1) Apex misplacement
First Fix
Correct placement strategy: keep strength where load is, keep cuticle and sidewalls clean and thin.
Don’t do
Don’t “hide” unevenness with more top coat. Fix the structure before finish layers.
Next step in the full training: Gel building & shaping workflows. For transition work: Oval → Square.
PAGE 14 Restoration vs Strengthening + Shape transition
If the nail has… You likely need… First Fix Damage, uneven plate, missing corners Restoration Recreate support points first, not “perfect shape.” Thin/flexible plate bends under load Strengthening Build strength in stress zone; keep everything else thin. Repeated breakage despite more product Structure correction Re-check apex, sidewalls, shape before changing materials.
Next step: Express Nail Restoration with Gel + Gel Strengthening.
Shape transition — Oval → Square | Transition without stress points Mistake Result First Fix Forcing corners without support Corner cracks / lifting Transition in steps. Maintain clean sidewalls and correct stress support as outline changes. Asymmetry in sidewalls Torque and breaks Bulking up to hold the square Thick profile, still fragile
Next step: From Oval to Square.
PAGE 15 Stamping & Pedicure quick fixes
Stamping — why it fails Problem Cause First Fix Doesn’t pick up design Timing + scraping pressure/angle Move fast and consistent Smudges on the nail Surface uneven or pressure inconsistent Prep surface clean and even Doesn’t last Finish sequence mismatch Seal correctly, don’t drown detail
Key: stabilize base surface first, then treat stamping as mechanical sequence: speed → angle → pressure.
Next step: Stamping (professional nail art technique).
Pedicure — durability & finish Problem Cause First Fix Finish looks rough Sequence / smoothing step missed Verify final smoothing before coating Result doesn’t last Breakdown at edges/pressure zones Adjust workflow order Uneven look Inconsistent surface control Careful finish placement
Key: treat pedicure like a protocol — correct order, consistent pressure, controlled finish.
Next step: Complete Pedicure Training.
PAGE 16 Mature hands adjustments (master-level detail)
Different constraints
Mature hands often require different visual control, finishing choices, and a more delicate approach to cleanliness and aesthetics.
What changes (in practice) Skin texture and cuticle area can behave differently during prep and finish. Structure has to look light and clean while still being durable. Small asymmetries are more visible — symmetry control matters more. First Fix: prioritize clean, light structure and a finish strategy that supports the hand visually.
Next step in the full training: Working with Mature Hands.
