I went into the hairdressers this week with light brown hair. I asked for a copper colour and they said I would need a darkish base on due to past blonde highlights. I said that was okay. However, I’m now as dark as ever (my children say my hair actually looks black it’s that dark) and I don’t think it’s copper, I think it’s mahogany….I would be so grateful for your thoughts please? Thank you in advance.
