Product Description

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.

It is also one of the strongest fibers in the world equal to steel. Because of this, Farouk Shami researched and discovered the benefits of silk proteins and how they could be applied to hair.

    I used Biosilk as a heat protectant before flat iron. It was easy to use, and provides lots of SHINE!!

  4. Mary

    I use this product before I blow dry my hair. I use a rounded brush and my hair is soft and smooth when finished.

  5. mariah

    I’ve only used it about 3 times but so far i like it. It doesn’t leave hair stiff or feel like you have product in it like some other heat protectants. I also use it with the biosilk oil and my hair looks shiny and feels good.

  6. Kate

    My fine color treated hair is dry at the ends, and the flat iron makes it worse. This protects and smooths, and doesn’t leave the hair sticky or crisp.

  7. Jones

    My hair can get dry in winter and this helps from trying my hair when blow drying or flat ironing.
