Okay, this symptom is called eyebrow hypotrichosis, and a 2023 paper titled Eyebrow Loss and the Queen Anne Sign in Hypothyroidism said that loss of the outer third of the eyebrows is called the Queen Anne sign, and it's an uncommon manifestation of hypothyroidism. However... The exact mechanism of eyebrow loss only at the outer third portion, it's unknown. They don't know why it happens.
