I am on t3 and t4 (Cytomel and Lyvoxl) and losing hair. Washing my hair (normally long and thick) yesterday, a nest the size of a golf ball came out. My scalp itches terribly and I am literally tearing my hair out. Most of the itching is at the crown, more on the right side than the left, and I'm getting a bald spot there. But all of the crown area has definitely thinned. I am on bio-idential HRT program which has been working well for two years. This has happened before when the weather is cold and dry - we heat with a woodstove, so zero humidity, but never this bad before.
What can I do to relive this?
