Coarse Facial Hair During GLP-1: Before Removal

New coarse facial hair during GLP-1 treatment deserves a discussion about its pattern and possible causes.

Describe the pattern, not just one hair

Hirsutism describes excess dark, thick hair in areas such as the face, chest or back in women. The Endocrine Society identifies PCOS as a common underlying cause, although other explanations exist. Tell your clinician about irregular or absent periods as well as hair changes; a chin hair alone does not establish PCOS. [1]

Testing depends on the examination

The Society's 2018 guideline addresses premenopausal women. It suggests androgen testing for an abnormal hirsutism score, but advises against routine testing for isolated local hair growth when periods are regular and that score is not abnormal. Ask which pattern your examination shows before ordering a hormone panel. [2]

Keep the surrounding skin in the plan

AAD advises seeing a dermatologist for a sudden increase in unwanted hair or skin problems caused by removal. Shaving can irritate skin, cause cuts and produce ingrown hairs. Assessment and a tolerable removal method belong in the same conversation; repeated irritation need not become the price of coverage. [3]
