Frequently Asked Questions
How hot should I set my curling iron or straightener for extensions and wigs?
Start low and increase gradually: test starting at 150°C (300°F) on a practice head and increase in 10–20°C steps only if the effect is insufficient. Human-hair extensions usually handle moderate heat, but synthetic blends and bonded areas require lower temperatures. Always test on a discreet strand first and keep contact time short.
Can heat protectant sprays prevent all heat damage?
Heat protectants reduce moisture loss and charring but don't make hair impervious. They let you use slightly higher temperatures more safely, but correct temperature, timing and technique are still essential. Practice applying the product and styling on a mannequin to learn how much protection you actually get.
Is it worth practicing on a mannequin before styling a client’s extensions or wig?
Yes. Practicing lets you refine sectioning, clamp pressure, combing tension and timing so you apply only the necessary heat. It also reveals how a specific extension or wig material responds to your tools and products, dramatically lowering the chance of accidental damage.
