Does levothyroxine cause hair loss?

If you’re wondering if thyroid medicine can cause hair loss, you’re not alone. Many people notice changes in their hair after starting treatment. Understanding why these changes happen can help a lot.
Understanding the link between thyroid medication and shedding
Studies show that up to 30 percent of people experience more hair loss in the first 12 weeks of taking levothyroxine. This is often when the body is adjusting to the new hormones. Thinning hair on thyroid medication is usually a temporary side effect.
Your hair follicles are very sensitive to changes in your metabolism. When you start levothyroxine hair thinning, your body is adjusting its internal balance. This can temporarily affect your hair growth cycle.
Primary mechanisms of hair loss
Doctors say there are two main ways hair loss happens when you start treatment. Knowing these can help you understand if it’s just a normal adjustment or if there’s a problem with your medication:
- Telogen Effluvium: This is the most common type, happening 2 to 4 months after starting treatment. It’s when hair follicles go into a resting phase too soon.
- Anagen Effluvium: This is a faster type of shedding, happening in days or weeks. It’s often caused by a sudden change, like too much medication.
The role of dosage in hair growth cycles
Your thyroid hormones need to be just right, or hair loss can happen. If your dose is too low, you might lose hair because your body isn’t getting enough hormones. On the other hand, can too high a dose of levothyroxine cause hair loss? Yes, too much can make your thyroid work too hard, affecting your hair growth.
