Hi I just wanted to update (not because anyone is interested in my hair but in case anyone else is thinking of doing a big change too.)
I went to the hairdresser yesterday and told her I wanted a dramatic change, and showed her photos of "ash blonde" hair after reading on this thread about cool undertones etc. Well she said I will probably never have that colour because red hair is nearly impossible to get rid of, she said it will take a long time to change the colour of my hair, that you can't just do it in one go. (Awwwww!)
She put a brown in (a flat brown if anyone understands this, I don't ) and then put caramel highlights. Then next time I can go a shade up and add more highlights and so on but it will take AGES. First step was to get rid of the red.
I told her that I was clueless because you see famous people going from one colour to another really quickly and she said its all fake and probably not even their real hair. It's just not possible to do that on normal people because it would look yellowy and you have to get the base colour right? Do you think that sounds right? If so then I will stick with her for a while and hopefully she knows what she is doing.
Anyway, it looks really far too dark to me, and I can barely see highlights, it is a bit shocking when I see it in the mirror, but I accept it's a gradual thing then hopefully by the end of the year it will be nice and very different.
Thanks very much for all the help and advice, I learned a lot from you, thank you.
