What Does It Mean When Your Nails Crack?
Healthy nails should be smooth, even, and free of cracks or splits. When they start to peel, break easily, or crack, your body is sending a signal—either your care routine needs improvement, or there may be an underlying health issue.
At DeLuxe Nina Nails, we focus not only on beauty but also on nail health. Let’s explore what’s behind cracked nails and how we can repair and protect them.

Common Causes of Cracked Nails
🔸 1. Aging and Natural Wear
As we get older, nails tend to become drier and more fragile. This natural process can be sped up by external factors.
What you might notice:
Frequent breakage
Matte or peeling surface
Slow nail growth
Our advice: Moisturize your nails and cuticles daily with nourishing oils. Check out our Ultimate Guide to Gel Nails to learn how to keep your nails protected long-term.
🔸 2. Harsh Products Weaken Nails
Some nail polishes, acetone-based removers, or cleaning chemicals can dry out natural nails severely.
Signs to watch for:
Yellowing nails
Brittle surface
Longitudinal cracks
DeLuxe solution: Choose strengthening treatments like BIAB (Builder in a Bottle) — a revolutionary method for fragile nails. Learn more here: Is BIAB Right for You?
🔸 3. Water: Friend or Foe?
Excessive exposure to water softens nails, making them bendy and prone to cracking. People who frequently wash dishes or clean without gloves may face this issue.
Symptoms:
Soft nails that bend easily
Peeling layers
Dry or fuzzy edges
Recommendation: Wear gloves when handling water and apply nourishing cream after each wash.


🔸 4. Nail Psoriasis and Other Skin Conditions
Psoriasis can affect the skin and nails, causing cracking accompanied by changes in color and texture.
What to look for:
Small pits or dents in nails
Yellow-brown discoloration
Nail detachment
Next steps: See a dermatologist for personalized treatment. Avoid irritants and use calming nail care products meanwhile.
🔸 5. Iron Deficiency = Fragile Nails
Iron deficiency anemia reduces oxygen circulation, including to your nails.
Common signs:
Fatigue
Flat or spoon-shaped nails
Cracked lips
Helpful tips: Take iron supplements, eat iron-rich foods like leafy greens and red meat, and consult your doctor.
🔸 6. Hormonal Imbalances (Thyroid Issues)
An underactive thyroid slows down cell regeneration, including nail growth.
Possible signs:
Slow-growing nails
Brittle edges
Dry skin and tiredness
What to do: Get blood tests, follow prescribed hormone therapy, and hydrate your hands and nails regularly.
🔸 7. Fungal Nail Infections
Fungal infections can make nails painful, thickened, and cracked.
Warning signs:
Yellowing
Thickened, cracked nails
Unpleasant odor
Treatment: Visit a dermatologist for topical or oral antifungal treatment. Maintain hygiene and avoid unlicensed salons.
🔸 8. Biotin (Vitamin B7) Deficiency
Biotin is essential for nail and hair cell regeneration.
Signs:
Nails peeling in layers
Dull or brittle hair
General fatigue
Sources: Eggs, nuts, seeds, and avocado are rich in biotin. Supplements can help but consult your doctor first.

🔸 9. Cancer Treatments
Chemotherapy and other aggressive treatments may cause nail cracking, thinning, or discoloration.
Gentle care: Talk to your oncologist about suitable nail care products. At DeLuxe Nina Nails, we offer gentle options designed for sensitive nails.
What to Do When Your Nail Cracks
🔹 Gently file edges with a fine nail file
🔹 Clean the area and avoid excess moisture
🔹 Use a silk nail patch or a DIY fix with tea bags and a protective top coat
🔹 Avoid superglue, which can irritate skin
