Hi. Greetings. Was thyroid levels ever done for your husband any time previously. Hypothyroidism can cause loss of eye brow hair. Is he losing it in sides only ? Or throughout ? Other causes could be alopecia areata, Hansen's disease. Please send snap on follow up chat/ or see a qualified dermatologist near you. Hope this helps
