Hi, @brendag60. It is really disappointing, isn't it, when we begin to feel so good after our transplant...until we look into the mirror! I remember that my hair was dull, wirey and thinning. I also remember that I didn't really care until My recovery was well underway. I also had problem fingernails that were dark and brittle. so at my 4/5 month check up I asked the transplant dermatologist what to do. He told me that some patients have good results by taking biotin, and suggested the amount which I don't remember. He said it could take a while, and it "might" work for me, but he also assured me that my labs were good and I was eating healthy foods, and that in time, my hair and nails would be normal again.
As for my hair., my beautician/cosmetologist who specialized in working with cancer patients had me use gentle shampoo and conditioner. I did not get any hair perms or get my hair colored. If you have a cosmetologist in your area, you might want to consult with them. Be patient because your hair will come back.
I remember going hiking at 9 months post transplant and while my hair was continuing to shed, my nails were coming loose and snagging on my clothing, so I actually wrapped each fingertip in surgical tape and wore gloves to protect them. Sounds yucky as I write this. I even figured out how to cut a fake nail covering out of clear surgical tape to cover my nails. I did n ot want to use any chemical products on m y nails. It worked for me and if anyone benefits from this idea, you/they are welcome to try it!

Brendag60, Congratulations on your recent kidney transplant! Other than your concern about hair loss, How is your recovery coming along? Have you been able to return to any of your normal activitites yet?

Congratulations on your transplant.
I had lost half of my hair due to COVID, then I lost half of what was left after the transplant. I tried Biotin for the first six-eight months with no help, my hair continued to fall out. Then I started on BioSil, which my transplant team ok'd (I check everything out with them first). Then my hair started the turn around. My hair is now thick again. However, the texture has changed some. I still have one spot (about the size of a nickel) that you can see my scalp, which I am going to try something topical, which the salon I go to recommended, and see how that works. I will let you know though if it works.
I have been going to the salon (or having them come to my house for the first few months) to have my hair colored since 3 months after my transplant. However, they use a very gentle product (Redken's chromatics) that has no ammonia (no fumes). Since, I am a double lung transplant recipient, I am very careful of my lungs and keep my mask on the whole time.
