How does NovaHair Instant Dye Shampoo work on completely gray hair?Updated 2 months ago

NovaHair Instant Dye Shampoo is designed to effectively cover gray hair by depositing rich, natural-looking color in just one wash. For completely gray hair, results may vary depending on hair texture and porosity. Coarse or resistant gray strands may require a longer application time or a second use for full coverage. We recommend following the instructions carefully and performing a strand test to achieve the best results.
