I’ve been using the Hairfinity Vitamins for the past 3 months. I’ve been using them with the shampoo, conditioner, both the Shine and the Volume Boosters. I’ve been seeing dramatic results from day one. The first month I was using the Shine Booster and I could tell from the first touch that my was a lot sleeker, a lot shinier. The second month I was transitioning into the Volume Booster Volume and have more volume and thickness now compared to the first month.
