When I was on chemo and lost all my hair, I started taking 50Kmcg/day of biotin. After the first year of that, I scaled it back to 30Kmcg/day. My hair returned as thick as it was before chemo and remains so on anastrozole. The one thing to remember is to stop all supplements at least 3 days before any blood tests (especially ones for thyroid) as biotin is among the supplements which distort blood assays.
