My hair feels greasy or limp since switching to New Wash. What's happening?

This is real, and it has a specific biological explanation. Your scalp has been stripped by detergent shampoo - possibly for years - and responded by overproducing oil to replace what kept being taken away. That overproduction became its new normal. Now the stripping has stopped, but your scalp is still producing oil at the elevated rate it calibrated to. That's the greasy feeling. Not a failure - a recovery. The scalp recalibrates on its own once the chronic disruption stops. For most people this takes two to four weeks. During that window: Use enough product - all of your hair needs to be coated, scalp to ends. Going short is the most common mistake. Add a small amount of water mid-application to help distribute evenly. Rinse for at least two minutes while actively working fingers through hair - New Wash needs movement to lift and rinse away completely. What's on the other side: hair in balance, your scalp producing what it actually needs rather than compensating.
