New Facial Hair After Menopause: When to Get It Checked
Menopause & HormonesArticleA few more chin hairs after menopause are common. The hormone balance shifts, and PCOS is the most frequent cause of excess male hormones at this age. Rarely, an ovarian or adrenal tumor is behind it. Endocrinology reviews name the red flags: hair that appears suddenly and spreads fast, a deepening voice, or other masculine changes. Here is how to tell the difference and what testing involves.
Plenty of women notice a few new chin hairs after menopause. Usually that’s an ordinary shift in hormone balance. Occasionally it’s a sign of something that needs a quick look.
Why it happens
After menopause, male hormones (androgens) can be relatively higher compared with estrogen. When they’re too high for the body, it’s called hyperandrogenism. The androgens come from the ovaries or the adrenal glands.1
The signs:1
- Excess hair in a male pattern (face, chest, belly), the most reliable sign
- Acne
- Thinning scalp hair
- In more serious cases, masculinizing changes (virilization)
Common versus rare causes
| Pattern | Likely cause |
|---|---|
| Mild, gradual hair or acne | The menopause transition itself, or PCOS, the most common cause at this age12 |
| Masculinizing changes | Ovarian hyperthecosis (overactive ovarian tissue) or, rarely, an androgen-producing tumor of the ovary or adrenal gland, which can be cancerous1 |
Excess androgens after menopause are rare overall.2 Tumors are rarer still, but they need to be found quickly.2
Medicines and hormone products can also cause it; see a partner’s testosterone gel.
Red flags
Ask for an urgent appointment if:23
- New thick, dark hair appears suddenly or spreads fast
- Your voice deepens
- Your muscles grow
These are the signs reviewers say should lead to imaging to rule out a tumor.2
What testing involves
- A testosterone blood test is the first step.1
- Imaging may follow to find the source: ultrasound or MRI of the ovaries, CT or MRI of the adrenal glands.1
- Treatment depends on the cause. Mild symptoms can be treated with anti-androgen medicines; a tumor usually means surgery.12
For how much hair is typical, see how much facial hair is normal and why you’re getting chin hairs.
Try: “I’m 62 and over the past three months I’ve grown dark hair on my chin and chest, and my voice sounds lower. Can we check my testosterone and look for a cause?”
My Body Changed. Now What? covers this in Chapter 9, “Desire, Skin and Hair,” in a section called “Acne, Chin Hair and the Part.” Its Visit Brief asks how fast a change started and what came with it, the two details that separate an ordinary shift from one that needs prompt testing. See the book.
