NIC Nail Technician Written ExamNail Technology ProceduresHard
A client complains that their recently applied gel polish is peeling from the free edge after only a few days. The technician confirms proper application steps were followed, including curing. What is the most likely cause of this issue?
- AThe UV lamp bulbs were too strong, over-curing the gel polish.
- BThe technician failed to 'cap' the free edge of the nail during application.
- CThe client's natural nails are too oily, preventing proper adhesion.
- DThe client used too much hand lotion, causing product breakdown.
Show answer & explanationAnswer & explanation
Correct answer: B. The technician failed to 'cap' the free edge of the nail during application.
Failing to 'cap' or seal the free edge of the nail with each layer of gel polish (base, color, top coat) is a very common cause of premature peeling and chipping from the free edge. This creates an unsealed edge where water and oils can penetrate, lifting the product.
Why the other options are wrong
- A. Over-curing is less common than under-curing and typically results in brittleness or cracking, not peeling from the free edge.
- C. Oily nails can prevent adhesion, but if proper prep (dehydration) was done, and peeling is *only* at the free edge, uncapped edges are a more specific cause.
- D. While excessive oils can affect adhesion, hand lotion is less likely to cause specific free-edge peeling if the product is properly sealed.
Capping the Free Edge
The technique of applying a thin layer of nail product (base, color, or top coat) over the free edge of the nail to seal it, preventing chipping and lifting.
- Crucial for gel polish and traditional polish longevity.
- Creates a protective barrier against moisture and wear.
- Performed with each layer of product application.
