This quest for healthier hair is how BioSilk Silk Therapy emerged in 1986. For centuries, silk was celebrated as a luxurious fabric due to its smooth texture and brilliant luster. Throughout history, silk clothed royalty and the elite, continually evolving with fashion trends to be one of the most coveted fabrics of all times. The launch of BioSilk Silk Therapy was yet another first since natural pure silk had never been used in hair care before. It was created as a weightless, leave-in silk replenishing and reconstructing treatment to repair, smooth and protect all hair types. BioSilk Silk Therapy continues to be one of the company’s strongest product offerings, winning countless beauty awards throughout the years, and is recognized brand among 97% of women. 5.64 fl oz
