Hi , thanks for reaching out here. Unfortunately, psoriasis can cause hair loss. The following article has some information on this, which I'm hoping will be helpful: https://plaquepsoriasis.com/symptoms-affect-body/hair-loss-scalp-flaking There are other conditions (and some medications) that can cause hair loss too, though. Are you treating your psoriasis with anything at the moment? Warmly, -Catherine, Community Moderator
