I dyed my hair for the first time ever last night. I did it at home using Naturtint 3N Dark Chestnut permanent colour. It's covered my greys well but the colour is darker than I realised - it's so hard to tell from the picture on the box. It's not a disaster but not quite the same as my natural colour. I think I should have gone one shade lighter (4N Chestnut).
Can I just use one shade lighter the next time I need to dye my hair? It suggests putting it on your roots for 30 minutes and the rest of your hair for 10 so I guess that would help it blend in a bit. Will it get lighter anyway over time as it's washed even though it says permanent? Help! I have no idea what I'm doing.
