Is Your Hair Falling Out? It Might Be Your Thyroid
Have you been noticing more hair in your brush lately? Or maybe your ponytail feels thinner than it used to? Don’t panic—but do pay attention. One of the hidden reasons for hair loss might be your thyroid.
Let’s break it down in a way that’s simple and easy to understand.
What Is the Thyroid?
Your thyroid is a small butterfly-shaped gland in your neck. Even though it’s small, it does a big job! It controls how fast your body works. This is called your metabolism.
Your thyroid helps with:
Energy levels
Body temperature
Heart rate
And yes… hair growth
When your thyroid isn’t working right, it can cause all sorts of problems—including hair thinning or shedding.
How Thyroid Problems Cause Hair Loss
There are two main ways your thyroid can get off track:
1. Hypothyroidism (Low Thyroid)
This happens when your thyroid isn’t making enough hormones. That can cause:
Dry, brittle hair
Hair falling out from your scalp
Hair loss in your eyebrows or eyelashes
2. Hyperthyroidism (Overactive Thyroid)
This happens when your thyroid is working too much. It can lead to:
Fine, thinning hair
Hair falling out faster than it grows
Both conditions mess with your body’s natural hair cycle, which means more hair ends up falling out—and less grows back.
Other Signs to Look Out For
If your hair is thinning and you also notice these symptoms, your thyroid might be the culprit:
Feeling tired all the time
Weight gain or loss you can’t explain
Feeling cold or hot often
Dry skin
Mood changes or anxiety
If this sounds like you, it’s a good idea to talk to your doctor and get a simple blood test.
Can the Hair Grow Back?
The good news? Yes, in most cases, your hair can grow back once your thyroid is treated. But it can take time—sometimes a few months—so be patient.
To help your hair while your body heals:
Eat foods rich in vitamins like B12, iron, and biotin
Avoid harsh styling or tight hairstyles
Use gentle, nourishing hair products
Stay consistent with your thyroid treatment
