Casting deep black

Start by assessing your hair history (porosity and condition), grey coverage needs, and how dark you want the final shade. Choose the casting deep black option if you want a rich, even result with gentler processing, as it is formulated to be kinder to the scalp. Consider how much maintenance you’re willing to commit to and follow the provided timing and aftercare directions for the best outcome.

Ammonia-free formulas like casting deep black deposit color without lifting the natural pigment, which typically means less odor and a milder feel on the scalp. They often include conditioning ingredients to help keep hair soft and shiny after coloring. Always follow the exact processing time stated in the instructions to achieve even coverage.

Casting deep black is suitable for both beginners and more experienced colorists, but the approach differs. Beginners should follow the kit directions closely, perform a strand test, and apply in small sections to avoid patchy results. More experienced users can focus on precise sectioning and timing to ensure uniform depth and coverage.

Use a color-safe, sulfate-free shampoo and cool water to wash hair, and limit washing frequency to preserve color. Protect your hair from excessive sun and heat, and adopt a conditioning routine to maintain softness and shine. Reapply according to the product’s guidance when you notice fading or regrowth.

Do a patch test 48 hours before use and perform a strand test to check color results. Section your hair evenly, wear gloves, and apply the product as instructed, ensuring complete saturation in each segment. After coloring, rinse thoroughly with cool water and use a conditioning treatment to seal in the color.
