Like anything else in life; diet, exercise, brushing your teeth, etc. if you do something to improve your health and then stop you will eventually go back to your prior state.
The same thing is true for your hair, but with Adegen we recommend using the topical to restore the health of your hair and some do that with just using the shampoo and brushing. Let’s say you use the topical and have great results; then, once you achieve the results you can maintain those with the shampoo and regular brushing.
At the end of the day, it's a lot easier to maintain than it is to restore.
