To be honest, after a trip to the hairdressers id normally go straight home and dunk myself to wash off the yukky smelling hairspray and salon shampoo, let it air dry back to its normal unruly style, so i do empathise with her!
Well she wanted to ruin matchie matchie ponies! She does not want to be dressed the same ! So what did you expect her to do ? She wants pugs, flamingos or sheep on her rug lol x
I used to ride a grey pony years ago and a few times I went to get her in she spotted me ran over to the puddle in the field and rolled in it, so you have my deepest sympathy!
