If you discontinue the use of Extra Strength Foam, it's probable that you will lose the hair you regrew during treatment within three to four months. For optimal results, continuous use is recommended. To ensure you don't run out of your hair loss treatment and stay on track with your hair regrowth journey, we will deliver a new bottle of Extra Strength Foam to you every month. By keeping your supply consistent, you will be able to maintain the hair you regrew during treatment and continue to stimulate new hair regrowth.
