@wschultz Welcome to Mayo Connect. We are patients/family members/caregivers here, and share our strength and experiences with others. We are not medical doctors. I can only imagine how frustrating and heartbreaking this situation must be for you. And your daughter may be very self-conscious about this turn of events. Have you been to see a rheumatologist to pin down the autoimmune condition? This may give you a clearer idea of what to/how to treat the hair loss. You're absolutely right, that stress can cause the hair loss, and going off to college can certainly be a stressor!
