You look adorable! I missed my long hair as soon as I chopped it, but short hair is so much easier to deal with. Especially in the summer.
On the point of dyed hair: And honestly, unless the company specifically has a policy against it, no one cares about dyed hair. I've had green hair, My Little Pony hair, purple hair, purple ends, and experimented with various tones and dyes in between, and no one has said anything about it.
It's been very refreshing from my time in the US where most of my employers had a dress code policy that discouraged "unnatural" hair colours.
