This is a direct dye to be added to Majirel or Majirouge permanent colour. It should not be used alone mixed with developer as it is not an oxidative colour. Really boosts the copper tones, but will wash out in about 3 to 4 weeks in my experience, of course that does still leave the base colour in place. I added half a tube to Majirouge 7.45 and achieved a very vibrant copper red. As with all colours do your patch test and follow the manufacturers instructions.Absolutely love this colour. Great for adding a real pop when mixed with the base copper. Terrible packaging though which has caused the end of the tube to burst. This is the 3rd time I've ordered this product and the 2nd time the product has been damaged. To brutalise Meatloaf "2 out of 3 IS bad, Amazon!"I live too far from a collection point and the fact that I even get a delivery service is a bonus in the North Wales mountains. It's not worth my while to try and return. But it's definitely something that needs changing with the way the item is packaged.FantasticQuesta tinta della L'oreal fa bene il suo dovere, il colore è fedele alla cartella colore e con l'aggiunta di 1/4 di mix copper red il colore diventa un bel rosso che si fa guardare, la confezione è arrivata un pò aperta ma per il resto tutto okSehr schöne Haarfarbe, sehr schnelle Lieferung.Ich habe LOREAL MAJIREL MIX KUPFER mit L`Oreal Majirouge 7,40 gemischt, sieht richtig schön aus, so etwa wie FeuerFür alle, die Feuerrot oder Kupfergold sein möchten genau richtige Entscheidung
