Something is not right with my hair.(+1 Magic)

Although the whole event was strange I decided it was no time to get angry about a dog. I started to move quickly and passed some fancy-looking girl. As I was walking I saw a glimpse of my reflection in a parked car window.

"Wait, are my hair blonde?" I thought. I couldn't believe my eyes, I simply stood there and looked at myself. After a few seconds of starting my hair slowly changed its color back to normal. I was a brunette once again. Was it possible that my hair changed? I decided to try some wishful thinking.

"I would like my hair to become blue." I thought to myself. A sudden rush of heat went from my head through my chest right into my finger where the ring was. And there I saw in a car window, that my hair started to change blue.

I wasn't sure what to think about it all but I had to rush to university, so I could make it in time for classes.
