I always ask for a semi as sometimes its a long time between haircuts. Normally I chose a colour close to my natural one as I just want to add a bit of shine/warmth.
I got my hair done in January. Now I have a decent amount of regrowth (thought my hair just held the colour longer!) but when I went to make an appt with a (new) hairdresser she said that I was given a permanent and not a semi 
Apparently its quite common, they just tell you its a semi but just put in a permanent? Anyway she wants to do a consultation before the colour to 'fix' the problem but I'd rather get an idea of what I want before so I don't have to pay for that [cheap].
Any ideas?
