Thyroid Hair Loss in Sioux Falls: Testing, Regrowth, and Density Support

5 min read Updated June 2026

Both hypothyroidism and hyperthyroidism can cause diffuse hair thinning. In South Dakota, thyroid disorders are diagnosed with a simple blood panel and treated by primary care or endocrinology. Once treatment stabilizes thyroid levels, hair typically regrows over 6 to 12 months.

Testing and diagnosis

The core panel is TSH, free T4, and often free T3 and thyroid antibodies. Ask your provider to include ferritin and vitamin D — deficiencies commonly co-occur and affect regrowth.

Endocrinologists at Sanford and Avera in Sioux Falls manage the more complex cases; primary care handles most straightforward hypothyroid diagnoses.

How we support you while your levels stabilize

Diffuse thinning is well suited to a lace-front topper that lifts the roots and adds density at the crown, or to an integration piece that weaves through your own hair for volume.

We do not recommend extensions during active thyroid-related shedding — the added weight can stress hair that is already fragile.

Frequently asked

Does thyroid hair grow back?
In most cases yes. Once thyroid levels are stabilized with medication, hair usually regrows over 6 to 12 months. Correcting co-occurring iron and vitamin D deficiencies speeds recovery.
Can I get extensions with thyroid hair loss?
We usually wait until shedding has stopped and thyroid levels are stable for at least 3 to 6 months before installing extensions. In the meantime, a topper or integration piece adds density without stressing fragile hair.
