@kearly, Good Morning, and Welcome to Connect! This is a great question that many many transplant patients have asked. I felt so poorly prior to transplant that my hair was very low on my list of concerns. It makes me happy to know that your loved one is feeling good enough to consider this!
Here is discussion that I want to share with you. Read, and ask your question there so that others with a similar experience will see it in the Daily Digest and be able to reply.
