A new bald patch during GLP-1 treatment deserves assessment before another hair product goes into your basket.

1. What pattern needs examination?

Alopecia areata can begin as a smooth, round or oval bald patch. Eyebrows, eyelashes and nails can also be affected, according to the American Academy of Dermatology (AAD). A photograph cannot establish your diagnosis. [1]

2. What will the dermatologist examine?

AAD describes examination of hair-loss areas and nails, sometimes with a magnifying dermatoscope. Health and family history matter. Some patients need hair sampling, biopsy or blood tests. [2]

3. What can treatment promise?

AAD says treatment depends on the extent, location and duration of loss and age. No treatment works for everyone; regrowth can be unpredictable. [2]

4. How should I handle my hair?

For diagnosed alopecia areata, AAD recommends a soft-bristled brush, wide-tooth comb, loose styles and air-drying. Ask about suitable products for your scalp. [3]

5. What about exposed scalp outdoors?

AAD recommends a wide-brimmed hat or scalp sunscreen with broad-spectrum, water-resistant SPF 30 or higher. Reapply sunscreen every two hours, after sweating and when the head gets wet. [3]

These US AAD pages concern alopecia areata, not GLP-1 trials or proof that medication caused a patch. For coverage decisions, see our wig guide.
