Ok I got 2 things about this.First... so Dash uses a special shampoo that dyes her hair? Wow I am shocked! Well not that shocked. I mean I guess that sounds very possible. I mean she is all about looking cool and how many rainbow maned ponies are there. She stands out and standing out helps you to get noticed. So, ya I guess I could see that.Seconds... and this is a pretty big questions. Umm.... why.... why was she using Dash's shower? Did she...umm.... spend the night plundering the cavern of 20% cooler? Did Dash get a private books signing? Where they role playing Twilight's latest writing endever? What ever the true reason. She owes Dash's some bits. I can't imagine that shampoo is cheap. Otherwise there would be more rainbow mains around.
