The shampoo works by depositing color while the conditioner-like ingredients help soften strands and improve manageability. It’s intended for temporary coverage that fades gradually with washes and hair growth. Always perform a patch test before first use to check for sensitivity.\u003c\/p\u003e\n\n\u003ch3\u003eHow simple is the application process for first-time users?\u003c\/h3\u003e\n\u003cp\u003eApplication is designed for at-home convenience: no mixing, no developer, and minimal tools required.

Results vary by hair porosity, initial color, and how often you shampoo, but many users see multi-week wear.
