I was diagnosed with Hypothyroidism about 9yrs ago after experiencing massive hair shedding. I took Levoxyl for several yrs, but due to insurance, was switched to the generic Levothyroxin (.75mcg). I've also taken birth control over the years, but switched to the Mirena IUD 7 months ago. My hair loss stopped after I initially started on medication, and actually thickened back up again 8yrs ago. My once beautiful thick hair which earned many compliments has been reduced to at least half of what it once was during the last 1.5-2yrs. My scalp is beginning to show thru more & more & it really freaks me out. I don't know what has changed, & have seen on here about other testing that I may need the doctor to run. We currently don't have insurance either, due to a lay-off, but I plan to go see the doctor the moment we get new insurance and need to know specifically what I need to ask the doctor.
