What You'll Learn
- Who benefits most from builder gel overlays
- Prep and application tips for thin nails
- How to avoid damage during removal
- The best length and shape choices for natural nails
Who Builder Gel Helps Most
- Clients with peeling or splitting nails
- People who want a natural look with extra strength
- DIY users who prefer short, low-maintenance nails
If nails are severely damaged or painful, pause and recover before applying any gel.
Prep for Natural Nails
Natural nails need gentle prep. Over-filing is the fastest way to thin them.

My prep rules:
- Lightly remove shine only.
- Avoid aggressive e-file work on the plate.
- Use dehydrator, then primer only if you lift.
Application Adjustments for Thin Nails
- Keep the apex modest and centered.
- Stay short to medium length.
- Use a self-leveling formula to avoid overworking.
If you want the full step sequence, follow the how-to guide.
