We worked tirelessly to create the best formulation for you for us. The proof is in the results. How long does it take for REVIVV^® to work? REVIVV starts working immediately. Most people start to notice benefits after about 1-2 months of consistent use.  Your scalp will typically start to feel better and you may start to notice the presence of peach fuzz (baby hairs).  Stay on course and over the next few months, you will be on your hair growth journey.  Individual results may vary.
