How long does the coffee tint last and what makes it fade faster or slower?

The colour is deposited by direct dyes that sit on the cuticle and outer hair shaft, so it gradually rinses away with each shampoo. Most people see noticeable tone for 4 to 8 washes, but the exact number depends on three main factors. First, hair porosity: more porous (often damaged or chemically treated) hair grabs more pigment initially but can also release it faster if the cuticle is very open. Second, starting colour: on medium-brown hair the coffee shade adds warmth and depth; on dark blonde it reads as a richer brown; on very light or bleached hair the result is significantly more intense and may last longer because there’s less natural pigment to compete with. Third, UV exposure: the formula includes a UV filter to slow sun-induced fading, but prolonged strong sunlight will still accelerate wash-out, especially for warm brown tones that tend to lose richness first. To extend the life of the tint, wash with lukewarm rather than hot water, use a sulphate-free shampoo for subsequent washes, and wear a hat or use a leave-in UV spray if you’re in strong sun for hours. Re-application is safe whenever the tone fades, since there’s no oxidative chemistry to build up.
