The first application of the Adegen ARB Topical Solution or ARB Shampoo+ SM Brush you are reversing the causes of hair loss immediately. However, this is happening at the hair follicle and not visible to the eye. You should start to see a visible difference at 30-45 days and you will see even greater results at the 90 day mark. The anagen (growth) phase of the hair cycle is 90-100 days, so it does take time for the hair to grow, but change is happening immediately.
It is extremely important to be consistent with the protocol if you want the best results. We can give you the most powerful and effective hair loss solution ever created but you need to trust the process and be consistent using the products and you will be glad that you did. We can't wait to hear about your success. Please take "before" pictures in good lighting to track your results.
