Perimenopause and facial hair: why it starts and what to do
One of the most disorienting parts of perimenopause is finding a coarse dark hair on your chin that was not there last month. It is extremely common, it is not a sign that anything is wrong with you, and there is a calm, gentle way to handle it.
Quick answer
Perimenopause causes facial hair because estrogen falls faster than testosterone, shifting the hormone ratio toward androgens. Even without a rise in absolute testosterone, that relative shift is enough to convert fine vellus follicles on the chin, upper lip, and jawline into coarse terminal hair. It typically starts in the 40s, is permanent unless managed, and responds best to a gentle removal routine rather than aggressive treatments on thinning skin.
What is actually happening to your hormones
Through perimenopause, ovarian estrogen production becomes erratic and then declines sharply. Testosterone, which women produce in small amounts in the ovaries and adrenal glands, declines much more slowly. The result is not high testosterone — it is a changed ratio. Estrogen normally acts as a brake on androgen effects in the skin, and when that brake weakens, follicles that were previously producing invisible peach fuzz begin producing pigmented terminal hair.
- 1
Estrogen drops
Ovarian output becomes erratic, then falls substantially through the perimenopausal transition.
- 2
Testosterone stays relatively steady
It declines gradually with age, but far more slowly than estrogen.
- 3
Ratio shifts toward androgens
Facial follicles lose the estrogen 'brake' on androgen signalling.

Vellus converts to terminal
Fine, colourless fuzz on the chin and lip becomes coarse, pigmented hair.
A general pattern. Individual hormone trajectories vary widely.
Where it shows up
- Chin and jawline — by far the most common, and usually the first place noticed.
- Upper lip — often a darkening and thickening of existing fuzz rather than brand-new hairs.
- Sideburns and cheeks — a gradual widening or darkening of the hairline edge.
- Neck — see our guide to neck hair removal for women.
Meanwhile many women notice the opposite in other places: thinner scalp hair, and less hair on the legs and underarms. That combination — more on the face, less on the head — is the classic androgen-ratio signature and is described in more detail in our menopause facial hair guide.
What is normal and what to get checked
| Pattern | Typical interpretation | Action |
|---|---|---|
| A few new dark chin or lip hairs over months or years | Very common in perimenopause | Cosmetic management is usually enough |
| Gradual darkening of upper lip fuzz | Common | Cosmetic management |
| Rapid, widespread growth over weeks | Not typical of perimenopause alone | See a doctor for androgen testing |
| Facial hair plus deepening voice or scalp hair loss | Possible virilizing cause | See a doctor promptly |
| Facial hair plus irregular cycles since your 20s | Consider PCOS rather than perimenopause | See our PCOS material and a clinician |
If your facial hair began well before your 40s and came with irregular periods, it may be PCOS rather than perimenopause — start with why PCOS causes chin hair and does chin hair mean PCOS.
The catch nobody warns you about: grey and white hairs
A large share of perimenopausal facial hair comes in unpigmented — white, silver, or pale blonde. This matters enormously for treatment choice, because laser and IPL work by targeting melanin. A colourless hair is effectively invisible to the machine. Many women book an expensive course of laser only to discover it thins the dark hairs and leaves the white ones untouched. Read can grey facial hair be permanently removed before booking anything.
A gentle perimenopause routine
- Choose a low-trauma removal method. Threading, dermaplaning, or a precision facial trimmer. See dermaplaning at home and threading vs waxing vs epilator.
- Support the barrier. A ceramide moisturiser at night, and daily SPF 30+. UV exposure worsens both pigmentation from removal and the underlying skin thinning.
- Use a daily topical to soften regrowth. Cyperus rotundus oil works on the follicle rather than on pigment, so it is unaffected by hair colour — Hadea Cyperus Rotundus Oil is applied twice daily after removal.
- Consider electrolysis for stubborn hairs. Slow and session-heavy, but the only method that permanently clears white hairs.
What to avoid on perimenopausal skin
- Hot hard wax on the cheeks or jaw — thinner skin lifts more easily.
- Depilatory creams on the face — the pH needed to dissolve hair is harsh on a compromised barrier.
- Bleaching — it masks rather than reduces, and irritates.
- Repetitive plucking of the same follicle — see what happens when you pluck chin hair.
Frequently asked questions
At what age does perimenopause facial hair usually start?
Most women first notice new coarse facial hairs somewhere between their early 40s and early 50s, though perimenopause can begin as early as the mid-30s. The change is usually gradual — one or two stray dark hairs at first, then more over a few years.
Is facial hair a sign of perimenopause?
It can be one of several signs, alongside irregular cycles, sleep changes, hot flushes, and mood shifts. On its own, a few new chin hairs is not diagnostic. If facial hair appears suddenly and rapidly, or comes with voice deepening or hair loss on the scalp, that is worth a doctor's visit to check androgen levels.
Will perimenopause facial hair go away after menopause?
Generally not. The hormonal shift that triggered the follicles to switch from fine vellus hair to coarse terminal hair does not reverse after menopause — for most women the hair stays and may slowly increase. It is managed rather than outgrown.
Does HRT stop perimenopause facial hair?
Hormone therapy is prescribed for menopausal symptoms, and some women report less new facial hair on it, but it is not a hair treatment and results vary considerably. This is a conversation for your doctor based on your whole health picture, not something to start for cosmetic reasons alone.
Why is perimenopause facial hair so coarse?
Follicles that switch from producing vellus hair to terminal hair produce a thicker shaft with a wider diameter and more pigment. It is the same follicle, but under androgen influence it behaves like a scalp or body hair follicle rather than a facial one.
Can I just pluck them?
Occasional plucking of a stray hair is fine. Repeated plucking of the same area can cause ingrown hairs, folliculitis, and post-inflammatory pigmentation, which is more likely on mature skin. Threading or a precision trimmer is usually gentler for anything more than one or two hairs.
Does laser work on perimenopause facial hair?
It works on hairs that still have pigment. A significant share of perimenopausal and menopausal facial hair grows in white, silver, or blonde, and laser cannot see those hairs at all. Electrolysis works regardless of color.
