Balmain DoubleHair Extensions are reusable hair extensions made from 100 percent human hair that add natural length and volume. Each extension weft is machine-made and can be attached using clips, soft rings, or keratin bonds for versatile styling options. One DoubleHair weft is equivalent to about 18 individual extensions, with a pack containing three wefts for a base volume treatment. For full volume or length, a minimum of five pieces is recommended. These extensions are 40 cm long and weigh 0.11 kg per pack, featuring color 10A ash blonde for a uniform, high-quality finish. They are designed for durability and reliability, seamlessly integrating with natural hair when using the Balmain Professional Aftercare series, ensuring long-lasting performance and easy maintenance for everyday use.
