I've been taking 50mcg a day of levothyroxine for an underactive thyroid for a year now. My hair has steadily gotten worse. Coarse & brittle.

In brief: TSH level

The proper dose of Levoxyl (thyroxine) is determined by the TSH level on blood testing.
Your md determines what that dose should be after the TSH results are known. If your TSH level is still too high(normal=0.5 to 5)you may need more than 50mcg of Levoxyl (thyroxine) per day.
