Why am I losing my hair?
Hair loss has many causes, and most are not obvious from looking in the mirror. Some are temporary and reversible, some are hereditary and progressive, and some are the first visible sign of a medical problem such as a thyroid condition or low iron. Because the cause decides the treatment, the most useful first step is an evaluation and a few targeted blood tests — not guessing at products.
Common causes we look for
| Cause | What it often looks like |
|---|---|
| Telogen effluvium (stress, illness, childbirth, surgery) | Diffuse shedding 2–4 months after a trigger; usually recovers |
| Thyroid disease | Thinning with fatigue, weight or temperature changes |
| Iron deficiency / low ferritin | Diffuse thinning, often with fatigue |
| Hormonal (menopause, postpartum, PCOS) | Thinning along the part or crown |
| Androgenetic (male & female pattern) | Receding hairline or widening part; hereditary, gradual |
| Alopecia areata (autoimmune) | Round, smooth patches of sudden loss |
The blood work-up for hair loss
Depending on your history, a hair-loss evaluation commonly includes thyroid testing (TSH), iron studies including ferritin, a complete blood count, and vitamin D — with hormone testing added when the pattern or symptoms point there. The goal is to find anything treatable before considering anything else. The American Academy of Dermatology describes the many causes of hair loss and why evaluation matters.
Medical treatment vs. restoration
When a blood test or exam finds a cause — a thyroid problem, low iron, a nutritional gap, a medication effect — treating that cause is what turns hair loss around, and that is primary care. For hereditary (pattern) hair loss, FDA-approved options such as topical minoxidil and, when appropriate, oral finasteride can help slow loss and support regrowth. When the goal is cosmetic restoration, our practice also offers PRP therapy and hair restoration — and a visit determines which path fits you.
Does insurance cover a hair loss evaluation?
The medical evaluation — the office visit and blood work to find a treatable cause — is covered medical care under Medicare and most commercial plans. Purely cosmetic restoration procedures are generally not covered. Insurance participation can change — call or text 214-810-4331 to confirm your specific plan before your visit.
