Entyvio and hair loss

My daughter had a Crohn’s flare this past year which culminated in surgery in August. During this time she has lost approximately 40 pounds. She came through the surgery fine but had no appetite and found it difficult to eat after the surgery. She is finding out what food she can tolerate now. She has been on Entyvio infusions and her last one was in September. Her hair is falling out by the handful. She is taking several medications, but we are thinking it is the Entyvio. Has anyone with Crohn’s suffered a severe hair loss? Has anyone had this happen due to Entyvio? Has the hair loss been permanent or does it grow back after a while?
