Biosilk Silk Therapy Drops offer a weightless, leave-in treatment designed to replenish, reconstruct, and protect all hair types. This iconic formula works to repair damaged hair by filling voids in the cuticle, which helps to prevent split ends and create a smooth, silky finish. Enriched with silk proteins, it strengthens strands from within while delivering brilliant shine. The versatile treatment can be applied to wet or dry hair, from scalp to ends, to leave hair revitalized, soft, and manageable without any added weight.
