We’re worried about going to Florida too! We generally spend winters there and missed last year because of Covid. We were prepared to be heading back in October. But now, with the surge again and the ‘powers that be’ not encouraging compliance, we’re really leery about heading down.

For your quick visit to Mayo though, you should be fine just following your normal stringent precautions for Covid. When we’re at any hotel we take along a container of Clorox or Lysol wipes. Both my husband and I know the routine. We start with each room and go around wiping doorknobs, doors where we’ll touch, horizontal surfaces of counters, tables, light switches, water faucets, tv remotes…and give the toilets a wipe down too. Since my transplant we even take Lysol spray to nuke around the toilet and floor, shower curtain. Yup, sounds severe but it has kept us safe. Oh, and do NOT drink out of the glasses in the bathrooms unless it’s the plastic cups sealed in a baggie. Take some Dixie cups along… Only takes a few minutes and then you’re not left wondering about safety. The clinic will require masks and have sanitizer everywhere! They’re so cautious you’ll be fine there.

Not sure I had hair loss from Tacro. I lost my hair 3 times from Chemo. Took a while after the 4th round to have it make a reappearance. I’m on such a low dose of tacro that I don’t think it’s having any impact on my hair.
I do know that any surgery, illness, anesthesia that could disrupt the growth cycle of hair will take time to regenerate. You might just be going through that phase of loss with no regrowth yet.
We have other members such as @ladydidehart, @gaylea1, @jolinda who have had success with Biotin. Their discussion is here in transplant an anti rejection med discussion. https://connect.mayoclinic.org/comment/308556/
