Final answer:
Yes, Joe can bump up the developer when adding Olaplex No.1 to a high lift color formula to compensate for the dilution effect of Olaplex and achieve the desired lift. It's important to follow manufacturer's guidelines and consider the hair's condition.
Step-by-step explanation:
When using Olaplex No.1 in a high lift color formula, it is indeed possible to bump up the developer. This is commonly done because Olaplex can dilute the developer, making it less effective. This helps achieve the desired lift or lightening effect. However, it is essential to follow the manufacturer's recommendations and take into account the client's hair condition to prevent damage. Typically, you might go one level higher with the developer. For instance, if you would usually use 20 volume developer, you might bump it up to 30 volume when using Olaplex.
