No, alopecia is not contagious. I have had alopecia univrsalis since my very early twenties. I met my wife when I was 23 and we married a couple of years later. Fast forward thirty years... My wife and our 26 year old son both have full heads of very thick and health hair. Don't be afraid of someone with alopecia. Few people understand the condition and too many people use their ignorance of it to be cruel. When I developed alopecia I lost friends. I was told that I looked like a dog with mange and some people asked that I not enter their homes because they were afraid of contracting my condition.
