Why Are My Nails Weak?

Weak nails, also known as brittle nails or onychoschizia, can stem from several factors. Let's explore the common causes:

Exposure to harsh chemicals: Frequent use of nail polish removers containing acetone, harsh detergents, and cleaning solutions can dry out and weaken nails. [Reference: Mayo Clinic Q and A, GoodRx, Healthline]
Exposure to cold, dry air: Cold weather significantly affects nail moisture levels, leading to brittleness and breakage. [Reference: Provided reference text]

Nutritional Deficiencies:

Biotin deficiency: Insufficient biotin intake can manifest as weak, brittle nails. [Reference: Provided reference text]
Iron deficiency: Anemia, caused by iron deficiency, is linked to weak and brittle nails. [Reference: Verywell Health, Health.com, WebMD, GoodRx]
Zinc deficiency: A lack of zinc can also contribute to nail fragility. [Reference: Verywell Health]

Hypothyroidism: An underactive thyroid gland can impact nail health, resulting in weakness and brittleness. [Reference: Healthline]
Psoriasis: This autoimmune skin condition can affect nails, making them brittle and prone to cracking. [Reference: Health.com, WebMD, Reddit]
Other hormonal imbalances: Various hormonal issues can affect nail strength. [Reference: Reddit]

Addressing weak nails often requires a multifaceted approach:

Moisturize regularly: Apply cuticle oil and hand cream daily to maintain hydration. [Reference: Reddit]
Limit exposure to harsh chemicals: Wear gloves when handling detergents and cleaning products. Use acetone-free nail polish remover sparingly.
Review your diet: Ensure you're consuming sufficient biotin, iron, and zinc through a balanced diet or supplements (consult a doctor before starting any supplement regimen).
Consult a doctor: If nail weakness persists despite lifestyle changes, consult a doctor to rule out any underlying medical conditions.
