Possible causes
- 01
Environmental dryness and irritant contact
commonFrequent handwashing, harsh soaps, and low humidity can strip natural oils, leading to dry, cracked skin and weak, brittle nails.
- 02
Iron deficiency anaemia
possibleInadequate iron levels impair oxygen delivery to tissues, frequently causing brittle, ridged, or spoon-shaped nails alongside dry skin.
- 03
Hypothyroidism
possibleAn underactive thyroid slows metabolism, reducing sweat and sebum production, which leads to dry, cracked skin and brittle nails.
Recommended tests
Iron & ferritin
→Ferritin, serum iron, TIBC — checks for iron-deficiency anaemia.
Why: To check for iron deficiency, a frequent and treatable cause of nail and skin changes.
Thyroid function panel
→TSH, Free T3, Free T4 — first-line test for fatigue, weight change, hair loss, mood.
Why: To evaluate thyroid hormone levels, as hypothyroidism commonly presents with dry skin and brittle nails.
GP consultation
→30–60 minute consultation with a British-trained GP — clinic, home or video.
Why: For a physical examination of the skin and nails to rule out fungal infections or eczema.
When to worry
- Nails that are separating from the nail bed (onycholysis)
- Signs of infection around the nails or skin cracks, such as pus, severe redness, or warmth
- Deep, painful skin cracks that bleed or do not heal
- Unexplained fatigue, weight changes, or feeling constantly cold
