What exactly is the 'Bond Re-Plex' and how does it work? Is this like Olaplex?

Bond Re-Plex is described in the product information as an amino acid complex. Its purpose is to work within the hair structure during the colouring process to help reduce breakage and make the hair feel more resilient afterwards. Permanent hair dye works by opening the hair cuticle in an alkaline environment and using an oxidant to remove natural pigment and deposit new colour. This process can temporarily weaken the internal protein bonds of the hair. The Bond Re-Plex ingredients are formulated to engage with the hair during this time, aiming to help it retain more of its internal strength. It's important to understand this is not identical to professional bond-building treatments like Olaplex, which use a specific patented molecule (bis-aminopropyl diglycol dimaleate) to seek out and repair broken disulfide bonds. While both concepts aim to protect hair during colouring, Bond Re-Plex represents this product's specific approach to hair care during the service, using an amino acid complex. It is a beneficial feature for a home colourant, focusing on condition, but it does not replace the need for general post-colour care with good quality conditioners and occasional treatments, especially if your hair is already damaged.
