Hair Thinning While Taking NDT?

Has anyone ever experienced thinning hair while taking any form of natural desiccated thyroid such as Naturethroid? I have tried it at doses of half grain to 1 grain a day, and within the first few days, I notice noticeable hair thinning in the front of my hairline. My labs show I need thyroid medication so it’s frustrating that my hair thins every time I take the medication.

There are a few possible things at play.

With hypothyroidism there can be generalized hair thinning and low metabolism. With restored thyroid levels perhaps hair follicle turnover with some transient hair loss as part of recovery. Many variables.
