Question: what is the difference between olaplex?
Answer: The main difference between Olaplex 2 and 3 is that Olaplex 2 is used at the salon and the Olaplex is an aftercare treatment, which means it's meant to be used at home. This makes it clear how the two should be used. With Olaplex 3, you can apply it yourself and you don't need professional knowledge to do so.
