The only "shocking" thing about it, is that it turns PINK!

Two and a half weeks ago I saw a professional hairdresser and had my natural hair fully bleached and toned to an amazing platinum blonde base. I asked her for a dark blue (Shocking Blue) to light blue (Blue Moon) ombre. The "Blue Moon" colour has lasted really well, unlike the "Shocking Blue" which is now bright PINK!? I'm super dissapointed!
