I have moved this to consumer queries as you state you are not a hair professional. It does state at the top of the Hair Forum :
If you are looking for advice and you are not a hair professional, then please post your query in the Consumer Queries forum.
Unfortunately it is also in the rules that we do not promote over the counter products, so you will not get a Hair pro to recommend a box colour, the best advice will be for you to consult a hair pro in a salon for your colour, as it will cost you more in the long run to get a colour correction treatment if/when an OTC colour goes wrong.
