The colour is very good, the shipment arrived on time. However, I had to dye it twice, because following the instructions provided by the seller did not give me a good result (uneven colour and colour stains). On the back of the dye packet I found a qrcode, which directed me directly to the manufacturer's page (which is not aybel) and there I found much more detailed and complete instructions. Fortunately, I had bought two sachets and tried to re-tint the same evening, following the manufacturer's instructions, and the result was excellent. Comparing the two instructions, I realised that the ones that came home from aybel were missing some basic steps (teaspoon of dishwashing liquid in the dye bath, water at 60 degrees, stirring CONTINUOUSLY for the first 10 min, etc). Overall, I would repurchase this product, following the instructions on the back of the label instead of the seller's leaflet.
