BB, I didn't know there was a biotin shampoo! I absolutely love how we can learn from each other. Thanks!
I'm sure you already have learned the value of patience, and that will be an asset as you wait and watch and hope for improvement. I don't remember how long it took until I noticed an improvement. I'm still not sure if it was the oral biotin or the post transplant recovery that are responsible, but my hair is definitely healthy now.
BB - I hope that there will be some good hair days ahead for you.
