Hair + scalp health at Circle
Hair loss can affect confidence, mental health, and quality of life. Addressing it early and thoughtfully can improve your current hair health and prevent further loss down the line.
We measure what most clinics skip
We look at all the possible causes of your hair loss. You review your results with a Circle physician so you know exactly what they mean, what you need to work on, and why.
Iron stores
Why we test it
When iron runs low, follicles shift into resting mode. This is the most common, fixable cause, especially for women.
Follicle cycling
Why we test it
Low vitamin D levels are linked to excess shedding. It's easy to fix, but rarely checked.
TSH
Why we test it
Both overactive and underactive thyroid can cause shedding. We rule it out in one blood draw.
Androgen signal
Why we test it
Elevated androgens can change the treatment plan entirely, particularly for women.
Growth cofactor
Why we test it
Deficiency weakens the hair shaft and slows regrowth.
CBC
Why we test it
This screens for anemia and hidden causes often mistaken for stress.
Markers shown are just some of what we test. This program includes a focused panel of 4–6 core markers*, and more may be added based on your clinical picture — chosen to provide the best care for your specific concern and clinical picture. Program testing is targeted only to your specific treatment program.
* Subject to physician confirmation of clinical eligibility and clinical assessment. Your Circle physician reviews your health intake and confirms which tests are appropriate for you; tests may be added or removed at their discretion.
