Can I pop into the meno salon for a trim please?

I've been colouring my hair for years and have tried most brands but now I use eSalon and it's the best I've found.
It's a web-based service: you answer lots of questions about your hair (colour, condition, how much grey you have, etc) - you can even upload a photo so they can see exactly what your hair's like (you don't have to, though). Then you pick a colour you'd like it to be (out of hundreds of shades!) and they mix a blend for you so that it works with your hair.
The only downside is that it's a US company so it takes a week to arrive after they ship it.
Once you've signed up, they send you your colour every six weeks - but you can easily change that or opt out completely and just re-order when you want. You can change shades whenever you want too.
Every other hair colour I've used has left my hair lank and horrible but this leaves it shiny and lovely for days afterwards.
(And no, I'm not on commission!)
