Strengthen and recondition dry, damaged and brittle hair with the Olaplex Hair Perfector 3. Containing the same active ingredient found within salon grade Olaplex treatments 1 and 2, the pioneering at-home treatment enables you to maintain healthier-looking hair with truly professional looking results.The advanced formula utilises a Bond Multiplying System; which seeks to reconnect broken disulphide sulphur bonds in hair, effectively resetting the hair from within to allow enhanced regrowth, structure and integrity. Suitable for all hair types, it prolongs colour vitality and vibrancy while strengthening the core follicle for a smoother, supple finish. The Olaplex 3 Bond Perfector is designed for at-home use. It is best to apply to towel-dried hair. If build-up is present such as oils or silicones, shampoo and towel dry before application for best results.This is NOT a conditioning treatment OR a leave-in treatment. It is meant to be shampooed out of the hair. Olaplex 3 must process a minimum of 10 minutes. If hair is compromised, 20+ mins is recommended. Once a week is suggested for healthy hair. For those with compromised hair, we recommend 2-3 times a week in combination with your favourite moisture and protein treatments where applicable.
