    CHI BioSilk Silk Therapy Serum – 167ml

    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 a recognized brand among 97% of women.

    Benefits:

    BioSilk Silk Therapy Original is a weightless leave-in silk replenishing and reconstructing treatment that helps repair, smooth, and protects all hair types.

    • Fills voids in the cuticle to create smooth hair
    • Aids in preventing split ends
    • Provides incredible shine

    How to use:

    Shake well before use. Place a small amount of silk therapy in the palms and apply from the scalp to the ends.

    May be used on wet or dry hair or skin.

    Use as often as necessary.
