Planning a respectful hairstyle workshop

I am organising a small digital portrait workshop at our library. One optional exercise would let adults explore a different hairstyle without suggesting that their existing appearance needs fixing. We can offer a set of practice portraits. Nobody needs to upload their own face. I am considering a hairstyle preview as a prompt for discussing shape and visual references, rather than making promises about a future haircut. The session would focus on describing choices. We could compare a bob with a longer cut. I would check the tool and its photo handling before including it, and provide a paper alternative for anyone who prefers that. Comments would be invited by the person taking part. We would avoid voting on anyone’s appearance. We could explain those expectations at the start. Which instructions would help beginners feel comfortable?
