Can too high a dose of levothyroxine cause hair loss?

Question

I've been taking levothyroxine for my thyroid for years, and lately, my hair fall has increased significantly. My sister, who also has thyroid issues, mentioned that sometimes the dosage can affect hair. Can too high a dose of levothyroxine cause hair loss?

Sanjay Gupta · Accepted Answer

Yes, it can, because both underdose and overdose of thyroid meds trigger hair fall. Before buying expensive hair serums, spend 400-500 rupees on a TSH blood test at a local lab. Show the report to your doctor so they can adjust your dosage.

Sister Jisha Joseph · Answer

Yes, absolutely. High levothyroxine levels can put your body into a temporary hyperthyroid state, which speeds up the hair shedding cycle. Don't stop or change the dose yourself; just ask your doctor to review your latest thyroid panel.

Rohan Sen · Answer

Yes, thyroid fluctuations can mess with hair health. Along with getting your dose corrected by a doctor, try staying active with a light 30-minute daily walk to manage overall stress, which also helps with hair recovery.

Oh yes, a high dose can definitely cause some temporary hair shedding! 😮 But don't worry at all, it's totally reversible once your levels are balanced. Just consult your doctor and get a simple blood test done! 👍

Vikas Hegde · Answer

My endocrinologist explained that temporary shedding is common when starting or changing the dose of levothyroxine. If the dose is too high, it mimics hyperthyroidism, leading to diffuse hair thinning. The key is to wait for your hormone levels to stabilize after a dosage adjustment.

I totally get it, losing hair like this is so stressful and makes you feel very low. But please remember, once your doctor corrects your thyroid levels, this shedding will stop and your hair will grow back. Keep patience.
