Frequently Asked Questions
Can clip-in extensions be curled or flat-ironed?
Yes — 100% human-hair clip-ins can generally be curled or flat-ironed up to the manufacturer's stated temperature (commonly around 250F/120C). Always use a heat protectant and avoid repeated extreme heat or bleaching, which shortens lifespan.
How do I prevent clip-ins from tangling during festivals?
Brush gently before and after wear, braid or tie hair loosely during high-activity periods, avoid sleeping with them in, and store in a breathable bag. Use a light leave-in conditioner or detangling spray and avoid heavy stickiness-causing products.
What should I look for in clips and the base?
Look for flat silicone or low-profile bases for invisibility and comfort, plus sturdy, tightly sewn metal clips that grip without tugging. These features reduce slipping and make the extensions more comfortable during long festival days.
