The Schwarzkopf Fibre Clinix Vibrancy Purple Shampoo is a gently cleansing shampoo that helps to neutralize warm undertones in blonde hair. It helps to increase hair vibrancy while also increasing the longevity of your color. The Schwarzkopf Fibre Clinix Vibrancy Purple Shampoo is formulated with Schwarzkopf's Triple Bonding and C21 Technology. Triple Bonding Technology builds new bonds through the creation of a 3-dimensional network inside the hair fiber, leading to hair that is up to 10x stronger, while C21 Technology is a highly effective, conditioning agent that works to protect and seal the hair's surface, restoring all C21-Lipid chains present in the cuticle. This tough-acting, yet gentle shampoo is ideal for those with chemically treated blonde hair that is in need of deep restoration and color preservation.
