Our money-back guarantee applies if you’ve used our Lashaddict Serum, Browaddict Serum, or Hairaddict Serum consistently for at least 12 weeks and have not seen any results. To qualify, you’ll need to provide clear, dated before-and-after photos of your lashes, brows, or hair, along with a photo of the used product, taken from your camera roll. Please ensure the photos are free from any makeup or mascara.
