The extensions are highly durable and are heat resistant up to 400F, meaning they can be styled the same as real hair. For a flawless look, they blend in with your natural hair seamlessly as they have human hair-like touch and feel. Your hair will look full and healthy as the clip-in extensions are double drawn and they’re even tangle-free, making them easy to maintain.
