Brittle or weak nails may signal underlying nutritional deficiencies, health issues, or external damage. Here’s a detailed breakdown:
1. Nutritional Deficiencies
- Protein deficiency: Nails are made of keratin, a protein, so low protein intake can cause weak or brittle nails.
- Iron deficiency: Low iron levels can lead to spoon-shaped nails or fragility.
- Biotin deficiency: Biotin (vitamin B7) is essential for strong nails. Lack of it can make nails brittle and prone to splitting.
- Other vitamins and minerals: Deficiencies in zinc, vitamin A, vitamin C, and calcium may also affect nail strength.
2. Health Conditions
- Thyroid disorders: Both hyperthyroidism and hypothyroidism can cause brittle nails.
- Fungal infections: These can make nails thick, discolored, and prone to breaking.
- Psoriasis or eczema: Skin conditions can affect the nail bed and weaken nails.
- Anemia or circulation issues: Poor blood circulation can reduce nail strength.
3. External Factors
- Frequent exposure to water or chemicals: Regular contact with detergents, cleaning agents, or harsh nail products can damage nails.
- Overuse of nail polish or acrylics: Chemicals in nail products can dry out nails and make them brittle.
- Mechanical trauma: Biting nails, frequent tapping, or heavy manual work can weaken them.
Tips for Stronger Nails
- Maintain a balanced diet rich in protein, vitamins, and minerals.
- Keep nails hydrated with oils or creams.
- Avoid harsh chemicals and limit acrylic or gel treatments.
- Protect nails with gloves when doing chores.
- Consider a biotin supplement if recommended by a healthcare professional.
Brittle nails often point to something that your body needs attention to, so addressing the root cause—whether dietary, medical, or environmental—can help restore their strength and health.
