@ladydidehart Hi, and Welcome to Connect. Congratulations on your transplant, you look fabulous for being 3 months post-transplant.

I had some hair loss also and biotin was recommended by my transplant team also, I think it must be fairly standard. Of course you should always check with your team before adding anything to your regimen. I do not recall the dosage that my transplant team recommended. The only caution about taking biotin is if you having a thyroid test, you should stop taking it a few days before. It does not cause any problems with the thyroid, just with the testing, and that depends on the type of test that the lab uses. Apparently there is more than one TSH test.
