Unfortunately I don't think I'll be returning to Oolong - I was taken 40 minutes late which with a 7pm appointment for cut and colour is already a bit of a late evening! My hairdresser was very apologetic so can't fault him for that but I left the salon with the same roots showing as when I went in...minus two little blonde streaks! Apparently it was a different bleach which was used which is better for the hair but I'm sorry to say it didn't make any difference on my dirty blonde roots.
