I think they fixed it up for him.When Lippe and him first got to Lippe’s home, the hair was messy and longer due to the uneven cut. The next morning, after he is dressup as a male and going through the day, his hair looked neat and short. So they must have cut it properly while getting ready in the morning.
julian impulsively cuts his hair as an act of rebellion and it's a perfectly symmetrical cut ╮( ̄▽ ̄)╭
