About this item Heat Resistant Fiber: A material that can withstand the heat from styling tools, offering similar styling options as human hair (best at 250-275 degrees). Avoid exceeding 350 degrees. It has a matte appearance, resembling real hair, and can be restyled using scissors or a curling iron. Cannot be curled with an iron: These hair extensions are crafted from heat-friendly synthetic fiber, allowing for easy straightening. However, unlike human hair, they cannot be curled using an iron. The manufacturing process involves special equipment and techniques to create curls. Differences from human hair: Unlike human hair, synthetic fibers tangle after 2-3 uses due to static from synthetic clothing, especially in winter. To prevent tangling, spray a water and conditioner mixture onto the extensions. Easy care instructions: To wash and care for the extensions, use mild shampoo and conditioner in lukewarm water. Air dry on a flat towel. If tangled, soak in diluted laundry detergent, rinse, then condition with fabric softener. Avoid blow-drying, sleeping, and swimming with them.
