https://www.fullshine.net/collections/virgin-genius-weft Full Shine's Genius Weft Hair Extensions are made of 100% human virgin hair. They are incredibly thin, flat and light, can last up to 12 months and reused 3-4 times with proper care. Our Genius Hair Wefts are most suitable for thick, coarse hair and can be cut anywhere without shedding. They perfectly circumvent hand-tied weft weakness, which means our genius weft hair extensions can be applied to any people.All Rights Reserved
