Nails often become drier, more brittle and prone to splitting around menopause. Learn the likely causes, which other conditions to rule out, and what helps.
Many women notice their nails become drier, more brittle, prone to peeling or splitting, or more ridged around menopause. Lower estrogen affects skin moisture and nail structure, and aging adds to it. Iron deficiency, thyroid problems or fungal infection can also cause changes. A dark streak under a nail needs prompt checking.
How strong is the evidence? Limited. Plausible, and commonly reported, but there’s little direct research.
Nails are made from layers of keratin, a protective protein. UK menopause clinic My Menopause Centre explains that nail changes in menopause are likely linked to the natural drop in estrogen and drier skin. When nails have too little moisture, they become brittle.
Nail specialists also note that nails contain small amounts of fats that keep them flexible, and research suggests their composition changes with age and sex hormones. Nail changes often appear alongside dry skin and thinning hair.
| Possible cause | Clues |
|---|---|
| Iron deficiency | Brittle or spoon-shaped nails, tiredness, heavy periods. See heavy bleeding. |
| Underactive thyroid | Slow-growing, brittle nails, tiredness, weight gain, feeling cold |
| Fungal nail infection | Thickened, discolored, crumbly nails, often toenails |
| Frequent wetting and drying, or cleaning products | Worse with housework or handwashing |
| Gel, acrylic nails and removers | Weakened nail surface |
| Psoriasis or eczema | Pitting, lifting nails, skin changes |
| Raynaud’s phenomenon | Fingers turning white or blue in the cold |
| Melanoma under the nail (rare) | A new dark brown or black streak, widening, or pigment spreading onto the skin |
See perimenopause or something else and fatigue.
A clinician will look at your nails and skin, ask about symptoms such as tiredness or heavy periods, and may suggest blood tests. These could include a blood count, ferritin (iron stores) and thyroid function. Nail clippings may be tested for fungal infection.

My Menopause Centre notes that a fingernail takes about six months to grow out, and a toenail up to 18 months. Improvements take time to show.
| When | What to do |
|---|---|
| After washing hands | Apply hand cream, massaging it into nails and cuticles |
| Before bed | Apply a richer cream or oil to nails and cuticles |
| Weekly | File nails short and smooth, in one direction |
| During housework | Wear gloves, ideally cotton-lined |
| Between manicures | Take breaks from polish, gels and acrylics |
Book an appointment if nail changes are persistent, painful, or come with other symptoms such as tiredness.
See a clinician promptly if you notice:
- A new dark line or streak in a nail, especially in one nail only, or one that widens
- Dark pigment spreading onto the surrounding skin
- A nail lifting, bleeding or changing shape without injury
- Painful, red, swollen skin around a nail
- Nail changes with tiredness, breathlessness or heavy periods

It can contribute, likely through lower estrogen and drier skin. Iron deficiency and thyroid problems should also be ruled out.
There’s little evidence unless you’re deficient, and high doses can interfere with some blood tests.
Lengthways ridges become more common with age. Sudden changes, or crosswise grooves, should be checked.
Fingernails take about six months to grow out, and toenails up to 18 months.
Yes. Iron deficiency can cause brittle or spoon-shaped nails. Ask for a blood test, especially if you also feel tired or have heavy periods.
