Procerin blocks DHT without reacting with testosterone (as some prescription medications do). This reduces, and can even halt, the further loss of hair from the scalp, without causing the sexual side effects of prescription drugs like finasteride (Propecia). Men of all ages, and all levels of hair loss, can benefit from Procerin. Whether you are concerned about stopping hair loss before it becomes a problem, or already have significant loss of hair, Procerin can help.
