Jon Renau's modern twist on the classic bob, includes wispy layers that create movement and style. SmartLace technology provides the most natural hairline available. No tape or glue needed! Lace front will conform to the shape of your head. Each individual hair is hand-tied to the lace, creating the illusion that the hair is growing from your own hairline. Renau's lace is indeed smart: it never unravels or runs and is so smooth and soft, you’ll never experience a discomfort. We love Renau's new Smart Lace wigs and so will you.
