Should I dye a test strand?Updated 4 months ago
We recommend doing a strand test if you’re unsure how the shade will look on your hair. Follow the same steps as you would for a full-color treatment. Pay close attention to pre-treatment, temperature, processing time, and consistency. Wrap the strand in foil and keep it warm (for example, with a turban or a cap). Rinse with plain water only, and evaluate the result after 48 hours.
