Procerin is safe to take in conjunction with other supplements and medications for treatment of hair loss. Many of our customers report great success using Procerin and Propecia together, since both products target different phases of DHT production. Topical treatments such as Rogaine will not interfere with the effectiveness of Procerin, and may help to increase your rate of hair regrowth. For topical use, we recommend using Procerin XT Topical Foam in conjunction with Procerin tablets for faster results.
