I lost all my hair also a few years back....I myself believe it's from a very sick colon and shock to the system and about
20% the medicine we take. it does grow back and I basically only took Biotin.and wore a lot of kerchiefs to cover the baldness. I also know all the crying in the world doesn't help it grow back either as I cried buckful of tears daily and I was in my 50's, but still working in the retail world and having to explain to everyone why I had no hair! They of course all thought it was cancer.... so we're all very lucky that way.
Here's a hug (((((( )))))

PS: And my hair grows very slowly but my nails I file down every week or so just wish the hair grew faster
