How long does the colour last and how does it fade?

Direct dyes wash out progressively rather than growing out. On pre-lightened hair the vivid tone usually stays strong for about 6–8 shampoos, then softens to a pastel pink that can linger for several more washes. On darker bases the reflective sheen disappears sooner, often within 3–5 washes. Factors that accelerate fading: hot water, clarifying or sulphate-heavy shampoos, frequent heat styling, and UV exposure. To extend wear, wash with cool water, use a colour-safe sulphate-free shampoo, limit heat, and consider a colour-depositing conditioner in a similar pink tone between applications. Because there is no ammonia or peroxide, re-application is safe whenever the colour fades — no need to wait for regrowth.
