Place the Greek yogurt in a medium-sized mixing bowl and whisk until smooth.
Add the dried dill, dried parsley, garlic powder, onion powder, sea salt, and black pepper to the bowl.
Whisk the dry ingredients into the yogurt until thoroughly incorporated.
Stir in the fresh lemon juice and finely chopped chives.
Gradually add the milk, one tablespoon at a time, whisking continuously until the desired dipping consistency is achieved.
Transfer the mixture to an airtight container.
Refrigerate for at least 30 minutes prior to serving to allow the dried herbs to rehydrate and the flavors to meld.
