I have one alopecia spot on the top of my head that still isn't growing back. I was just diagnosed with telogen effluvium after a biopsy so I'm sure stress from my bald spot has onset TE and its preventing my hair from coming back but has anyone else had Alopecia Areata and had it take this long or longer to come back? Additionally, has anyone used minoxidil on one spot? I know on the box it says not to use it on patchy hair but if it's just on the spot that has no hair I don't see the harm. I had alopecia 7 years ago and lost almost all of my hair but it started growing back 3 months after it fell out.
