'Nisim™ Hair and Scalp Extract AKA Stimulating Extracts are MASSAGED into the scalp twice a day. The Extract is a leave-in treatment. Nisim™ is the ONLY non prescription product that can and does provide PROOF of its ability to neutralize DHT. Nisim™ does not rely on chemical irritants that cause skin irritation for vasodilation. Natural vasodilation occurs when the treatment is massaged into the scalp. The Extracts must be used in conjunction with Nisim™ Shampoos, the extracts are not a stand alone product. When you have achieved the desired results (typically 18-24 months) you can discontinue the use of the Stimulating Extract and maintain your hair using only the Nisim™ Shampoo. This is not a product you have to use for the rest of your life.

Box contains four 50mL(1.7 fl.oz.)bottles of Nisim Hair and Scalp Extract. approximately a 6-8 week supply.
