We are all unique. As is the case with a regimen of any kind, some people feel a huge difference immediately, and it takes time for others. Very damaged hair or very irritated scalps may take longer to respond, and overactive oil glands may need time to re-calibrate their output. We urge you to be patient and diligent as your system adjusts to life without detergent.
Many people are attracted to New Wash by the promise of less frequent washing, but we suggest that oil-prone types put that goal aside and wash more frequently for a few weeks, or twice the first few times.
