How long will Hair Tinsel last? Properly installed, Hair Tinsel can last 4-8 weeks or longer and will withstand everyday washing and styling. Everyone normally sheds approximately 50-100 strands per day, so the Hair Tinsel will fall when the hair it is tied to falls out naturally. Can hair tinsel take heat? The material is heat-resistant, meaning you can continue using a blow dryer, curling iron, or other styling tool. And you can keep your shampoo routine too. Other things you need to pay attention to: 1.Keep the crochet needles and microlink beads away from children. 2.The surface of pliers has oil stains to prevent rust, please wipe it before use.3.Avoid prolonged exposure to your flat iron, curling iron or hair dryer, even though hair tinsel is heat resistant.
