Olaplex No.4 Bond Maintenance Shampoo 

Made in California and loved by hair stylists all over the world, Olaplex is the innovative brand that changed the game for hair treatments. This unique and patented chemistry starts with a single active ingredient, Bis-Aminopropyl Diglycol Dimaleate. Olaplex works by finding single sulfur hydrogen bonds and cross linking them back together to form disulfide bonds before, during and after services. Disulfide bonds are broken via chemical, thermal, and mechanical processes. Bonds break when exposed to chemicals in colour, from heat, and mechanical force such as combing wet hair.
By utilising the magic of Olaplex, your hair is protected against breakage when colouring or lightening, leaving your locks healthy, shiny and fresh. 

Olaplex is free of silicone, sulfates, phthalates, DEA, aldehydes, gluten and is never tested on animals. 

N°4 Shampoo repairs and protects hair from everyday stresses — including damaged hair, split ends, and frizz — by re-linking broken bonds. Leaves hair easier to manage, shinier and healthier with each use. N°4 is color-safe and proven to reduce breakage and strengthen all types of hair.

PH Balance: 6-6.5
