Does Rowan have short or long hair???

I looked at the fandom wiki midway through Heir of Fire and found this.. I thought Rowan had long hair.. I looked up "Rowan TOG" and theres SO MANY short hair photos!!

I went back and read the description of Rowan when he approaches Celaena and it didn't mention his hair length HOWEVER when she has him tattoo her it says his hair was tied back..

I know the wiki fandom is that, fan art but I wanted to ask if anyone else envisioned him with long hair as apposed to the short? I have included something I found that hits prwtty close to how I imagined him for this whole book
