You've noticed it. Your lashes don't look the way they used to. They're shorter, sparser, and no amount of mascara seems to fix it. If you're in your 40s, perimenopause could be the reason — and you're far from alone.
What Is Perimenopause, Exactly?
Perimenopause is the transitional phase before menopause — it can begin as early as your late 30s and typically lasts 4–10 years. During this time, oestrogen and progesterone levels fluctuate unpredictably before eventually declining.
Most people associate perimenopause with hot flushes and irregular periods. But the hormonal shifts affect far more than that — including your hair, skin, and yes, your eyelashes.
How Hormones Affect Your Lashes
Oestrogen plays a key role in the hair growth cycle. It helps keep hair follicles in the anagen (growth) phase for longer, which means more time for lashes to grow before they shed.
As oestrogen levels drop during perimenopause:
- The anagen phase shortens — lashes spend less time growing and more time resting or shedding
- Follicle sensitivity increases — lashes become more reactive to androgens, which can miniaturise the follicle over time
- Skin and follicle hydration decreases — drier conditions mean lashes are more brittle and prone to breakage
- Cell turnover slows — new lash cells are produced more slowly, leading to thinner, finer lashes
The result? Lashes that look noticeably shorter, sparser, and less defined — even if you haven't changed anything about your routine.
Signs Your Lash Loss Is Hormonal
- Gradual thinning that started in your 40s with no other obvious cause
- Happening alongside other perimenopausal symptoms (irregular periods, skin dryness, mood changes)
- Lashes feel more brittle or break more easily than before
- Noticeable thinning at the outer corners of the lash line
What Actually Helps
1. Use a targeted lash serum
A peptide-based lash serum compensates for what declining oestrogen is no longer doing naturally — keeping follicles in the growth phase for longer. Look for:
- Myristoyl Pentapeptide-17 — clinically studied to support lash growth at the follicle level
- Biotin — supports keratin production
- Panthenol (Pro-Vitamin B5) — conditions and strengthens the lash shaft
- Hyaluronic Acid — hydrates the follicle environment, counteracting perimenopausal dryness

2. Be gentler with your lashes
Perimenopausal lashes are more fragile. Small habit changes make a real difference:
- Switch from waterproof to regular mascara where possible
- Use an oil-based or micellar remover and press gently rather than rubbing
- Avoid eyelash curlers on dry lashes — always curl before mascara, never after
- Take regular mascara-free days to let lashes breathe
3. Support from the inside
- Biotin — eggs, nuts, seeds
- Iron — leafy greens, red meat, lentils (low iron is a commonly overlooked cause of lash loss)
- Omega-3s — oily fish, flaxseed
- Protein — lashes are made of keratin; adequate intake is essential
4. Consider speaking to your GP about HRT
HRT addresses the root cause of perimenopausal symptoms including lash thinning. Not right for everyone, but worth discussing with your doctor.
What to Expect from a Lash Serum During Perimenopause
Results take a little longer when hormonal factors are at play — but they do come.
| Week | What You'll Notice |
|---|---|
| 1–4 | Less shedding; existing lashes feel stronger |
| 4–8 | Early lengthening, particularly at the outer corners |
| 8–12 | Visible improvement in fullness and density |
| 12+ | Continued improvement; maintain with regular use |
Consistency is everything. Give it the full 12 weeks before judging results.

FAQs
Will my lashes grow back after perimenopause? For most women, yes. Lash thinning during perimenopause is not permanent. A lash serum can help accelerate recovery.
Can I use a lash serum if I'm on HRT? Yes — a peptide-based serum is fully compatible with HRT. They work through different mechanisms and complement each other well.
How is perimenopause lash loss different from menopause lash loss? The cause is the same (declining oestrogen), but perimenopause involves more fluctuation — which can make lash loss feel more unpredictable.
Is lash loss during perimenopause normal? Very. It's one of the lesser-discussed symptoms, but extremely common. You're not imagining it.
