Q. What causes brittle nails, and how can I strengthen them?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Brittle nails are characterized by nails that are weak, easily break, or split. There are several potential causes for brittle nails, and addressing the underlying cause is key to strengthening them. Here are some common causes and ways to strengthen brittle nails:
Causes of Brittle Nails:
1. Excessive Moisture: Repeated wetting and drying of the nails can cause them to become brittle.
2. Harsh Chemicals: Frequent exposure to harsh chemicals, such as nail polish remover or cleaning products, can weaken nails.
3. Age: As people age, their nails may naturally become more brittle.
4. Nutritional Deficiencies: A lack of essential nutrients, particularly biotin, can lead to brittle nails.
5. Dehydration: Not getting enough water can lead to dry and brittle nails.
6. Medical Conditions: Certain medical conditions, such as thyroid disorders and psoriasis, can affect the nails.
7. Medications: Some medications can have a side effect of causing brittle nails.
8. Lack of Moisture: Overly dry nails are prone to becoming brittle.
Ways to Strengthen Brittle Nails:
1. Maintain Good Nail Hygiene: Keep your nails clean and dry. Avoid excessive exposure to water, and use gloves when working with water or chemicals.
2. Limit the Use of Nail Polish and Polish Remover: Frequent use of nail polish and harsh polish removers can weaken nails. Allow your nails to "breathe" by giving them breaks from nail polish.
3. Moisturize: Apply a moisturizing nail and cuticle cream or oil to keep the nails hydrated.
4. Protect Your Nails: Wear gloves when doing household chores or tasks that involve exposure to harsh chemicals.
5. Dietary Changes: Ensure you have a balanced diet with adequate nutrients. Biotin supplements may be helpful for some people with brittle nails, but consult a healthcare professional before taking supplements.
6. Stay Hydrated: Drink enough water to maintain overall hydration.
7. Avoid Biting or Picking Your Nails: These habits can damage the nails and make them more brittle.
8. Use a Nail Strengthener: Consider using a nail strengthener or hardener product. Some contain ingredients like formaldehyde that can help strengthen nails. Follow the product instructions carefully.
9. Gentle Nail Care: Be gentle when filing or shaping your nails, and avoid excessive buffing.
10. Consult a Dermatologist: If your brittle nails persist despite home remedies or if they are causing you concern, consult a dermatologist for a professional evaluation.
Remember that it may take time to see improvements in the strength and appearance of your nails, so be patient and consistent with your nail care routine.
