In case you ever need to know, rubbing alcohol will effectively remove orange silly putty from long blond little girl hair. (The colors, lengths, and genders are for story-telling purposes only and need not apply. It’ll work either way.)
This is not some useless wives’ tale I’ve heard floating around the block. It’s tried and true. It’s also not a bit of knowledge one should ever find need for, yet I did. And there you have it.
Fear not the hair putty! You have a defense.
