Should I dye a test strand?Updated a month ago
We recommend testing a strand if you are very unsure about how the shade will look on your hair. Follow the same procedure as for a full color treatment. Pay attention to the pre-treatment, temperature, processing time, and consistency. Wrap the strand in foil and keep it warm (for example, with a turban or by putting on a cap). Again, rinse with clear water only and assess the result after 48 hours.
