R+CO Golden Lining Bond Builder Pre-Shampoo Filler Concentrate 12/0.5oz

Two-pronged repair in a flash. Reversing damage both inside and out caused by chemical services, heat styling and free radicals, this prescription-grade formula harnesses vegan keratin to rebuild broken bonds in the inner cortical structure, while botanical extracts patch porous areas, restore elasticity and saturate hair with crucial hydration. Hair is left stronger, softer and less prone to breakage. Necessary repair for overstressed hair.

Standout ingredient—Vegan Keratin penetrates deep into the hair’s inner cortex, reinforcing the cortical structure to provide instant tensile strength and elasticity.

67% increase in instant tensile strength + inner hair repair*
85% increase in hydration + softness**
Fills in porosity of damaged hair + prevents further breakage***
