Heat spikes are something most nail techs have experienced during a builder or hard gel service. That sudden sensation of heat can be uncomfortable for clients, but with the right techniques and equipment, it can be minimised.
Here's what every professional nail tech should know.
What Causes Heat Spikes?
When builder and hard gels cure under a UV/LED lamp, they undergo a chemical reaction called polymerisation, which releases heat.
This is completely normal, but certain factors can make the heat more noticeable, including:
-
Thick product application: Excessive amounts of gel can generate more heat during curing.
-
Natural nail condition: Thin, damaged or over-filed nails can be more sensitive.
-
Curing intensity: A rapid curing reaction can result in a more noticeable heat spike.
4 Ways to Minimise Heat Spikes
1. Perfect Your Product Application
Avoid applying excessively thick layers of builder or hard gel. Focus on controlled product placement and creating the correct structure without unnecessary bulk.
2. Use a Low Heat Curing Mode
A dedicated Low Heat setting helps manage the initial curing reaction, reducing the intensity of heat experienced by the client.
The TWENTY™ Smart Lamp 2.0 features a 99-second Low Heat mode, ideal for curing compatible BUILD & BOOST™ and SCULPT & BOOST™ gel systems.
3. Protect the Natural Nail
Over-filing can leave the natural nail more sensitive to heat. Always use gentle, controlled preparation techniques and avoid unnecessary removal of the natural nail plate.
4. Never Ignore Discomfort
If your client experiences a heat spike, ask them to remove their hand from the lamp immediately. Allow the sensation to subside and review your application and curing technique before continuing according to the product instructions.
