Hair coloring in Amsterdam

Single-process color covers the whole head in one shade — the right call for covering grey, going darker or refreshing a faded base. If your color is fine and only the roots betray you, a root touch-up costs less and spares the lengths; stretching full color over already-colored ends is what makes hair feel like straw by spring. A gloss or toner is the lightest option: it does not lift, only corrects tone — killing brassiness after a summer or adding shine before an event — and washes out gradually over four to six weeks. Going more than two shades lighter is not a single-process job at all; that conversation starts with a strand test.

Tell the colorist your hair history honestly — box dye, henna, a bleach from two years ago all still live in the lengths and change how new color takes. Henna especially: over it, many salon colors turn unpredictable, and a strand test is not optional. Come with hair washed a day ago, not freshly scrubbed skin. Afterwards, wait forty-eight hours before the first wash, switch to sulfate-free shampoo and wash cooler — hot water opens the cuticle and rinses pigment out. Book the next roots at four to six weeks for grey coverage; a photo of your hair in daylight right after the visit gives the next appointment an exact target.
