Hi, I am new to this forum. Androgenetic alopecia runs in my family. It has affected my paternal grandmother, my sister, my niece, me and now my 11 year old daughter is showing signs of it, and it’s causing a lot of distress for me. The rest of us didn’t have symptoms of it until we were in our 20s, but my 11 year old has not even started menstruating yet and already her part is pretty wide. I’m attaching some pictures. I’m wondering if it’s really possible to show symptoms of androgenetic alopecia this early or if there is another reason she may be losing her hair. I recently took her to an endocrinologist. They found that her thyroid is elevated (hypothyroidism) but didn’t think this could cause hairloss and said it wasn’t severe enough to even treat. They want me to bring her back in 6 months for a follow-up. However, I keep reading online that this could be the cause and wondering if I should get a second opinion. I have an appointment with a dermatologist. What can I expect there? Can they perform some tests to give a more definitive diagnosis or should I just expect to be told to start her on rogaine without any testing? I also want to take her to an allergist to have her tested for a gluten sensitivity. My sister-in-law has celiac disease, which caused hairloss for her. Could this be the culprit! I am also considering having a test done for vitamin deficiency. I’m not sure if this test would be performed by a dermatologist or if I need to take her to a pediatrician. I read that an iron deficiency could cause hairloss. Any advice you can offer is greatly appreciated!
