I am a 43 yr old f. My head is itchy at times and my hair is falling out. My doctor ordered blood work to check my thyroid. What's wrong with me?

In brief: Hair loss

By far the most common cause of hair loss in men is androgenetic alopecia, also referred to as “male pattern” or “common” baldness.
It is caused by the effects of the male hormone dihydrotestosterone (dht) on genetically susceptible scalp hair follicles. Other causes include medications, systemic disease as in lupus and thyroid disease.
