You may already be aware of the details/publicity in the link below, but just in case I thought I'd post.
I am also a member of Thyroiduk.org but today I was listening to the Radio this morning LBC and it was about a 'cure' for Alopecia.
Apparently they say there is a 'cure' so I'll give the link below and members can summarise what they think of it.
I have had steroid injections in the past but Alopecia Areata returned again.
If you cursor down to the arrow to listen to the video by the Researchers.
