Nails are an important part of the beauty of our hands. However, many people face the problem of fragile and brittle nails. Daily activities such as washing dishes, typing, or doing household chores can thin, crack, or even break nails. When nails are in poor condition, not only does it affect their appearance, but it can also cause discomfort. How can we restore healthy, strong nails? I’ll be sharing some effective methods for nail care to help you achieve healthier, more beautiful nails.
1. Common Causes of Fragile Nails
Before we dive into the care tips, let’s first understand why nails become fragile. Here are a few common reasons:
1.1 Nutrient Deficiency
Nail health is closely related to the overall nutritional status of our body. If you’re lacking in vitamins and minerals, your nails are more likely to become brittle. Specifically, a lack of biotin (vitamin B7), vitamin E, zinc, and iron can cause nails to crack and break.
1.2 Environmental Factors
Climate changes, frequent exposure to cleaning agents, or excessive moisture can negatively affect nails. For example, cold and dry air can make nails drier, causing cracks to appear.
1.3 Improper Nail Care
Improper trimming, excessive use of chemical products (like nail polish and removers), or overtrimming the edges of nails can also make them more fragile. Additionally, frequent use of artificial nails, gel nails, and other nail enhancements may cause damage.
1.4 Health Issues
Certain health issues such as thyroid disorders, anemia, skin conditions, or fungal infections can lead to weak nails. Chronic stress and lack of sleep can also negatively affect your health, in turn impacting your nails.
2. Are Nail Strengtheners Effective?
A common question is whether nail strengtheners are effective. In reality, the effectiveness of nail strengtheners varies from person to person. Most nail strengtheners on the market contain strengthening ingredients that help provide the nutrients necessary for nail repair and regeneration. These typically include biotin, vitamin E, keratin, and calcium, all of which are essential for nail health.
Using nail strengtheners can help improve brittle nails, but the results usually take time to show. Here are some common effects of using nail strengtheners:
- Stronger Nails: By applying nail strengtheners, you can increase nail resilience and reduce breakage.
- Promote Nail Growth: Some nail strengtheners contain ingredients that help promote healthy nail growth, especially those with biotin.
- Repair Brittle Nails: Some products nourish and repair dry, cracked nails, restoring their shine.
3. What Actually Helps Nails Grow?
Nail growth is a long-term process, and there is no magical solution for instant results. However, scientifically-backed care methods can significantly promote healthy nail growth. Here are some effective suggestions for encouraging nail growth:
3.1 Maintain a Healthy Diet
If you want strong, healthy nails, you need to ensure you’re getting enough nutrients. Here are some nutrients particularly beneficial for nail growth:
- Biotin: Biotin helps enhance nail thickness and strength, preventing breakage. Common biotin-rich foods include eggs, milk, almonds, and sweet potatoes.
- Vitamin E: Vitamin E helps maintain nail moisture and elasticity. You can get vitamin E from foods like nuts and vegetable oils.
- Zinc: Zinc is an essential mineral for cell regeneration and helps repair damaged nails. Beef, oysters, and beans are good sources of zinc.
- Iron: Iron keeps your blood healthy and provides the nutrients needed for nail growth. Leafy greens, red meat, and beans are great sources of iron.
3.2 Maintain Nail Hydration
Nail hydration is extremely important. If nails become too dry, they are more likely to crack. If they become too moist, they may weaken. Applying nourishing nail oil or cuticle oil daily can help maintain hydration and softness for your nails.
3.3 Avoid Over-Trimming Nails
Over-trimming nails, especially the edges, can make nails more fragile. The correct way to trim nails is to gently shape the length and edges without overdoing it.
3.4 Regular Use of Nail Care Oil
Nail care oil is rich in plant extracts and moisturizing ingredients, which can promote healthy nail growth. Massaging nail oil into your nails and cuticles every day can strengthen the nails and prevent cracking.

4. What to Look for When Choosing Nail Strengtheners?
When choosing a nail strengthener, here are a few factors to consider:
4.1 Ingredients
Look for nail strengtheners that contain beneficial ingredients such as biotin, vitamin E, keratin, and calcium. These ingredients are crucial for nail repair and strengthening.
4.2 Avoid Harsh Chemicals
Some nail strengtheners contain harsh chemicals, such as formaldehyde, which can harm your nails. Choose products with gentle, non-irritating formulas whenever possible.
4.3 Brand Reputation
Brand reputation is another important reference point when purchasing nail strengtheners. Well-known international brands, such as OPI, Essie, and Revlon, offer excellent nail care products that have been highly praised by consumers.
5. How Long Does It Take to See Results from Using Nail Strengtheners?
Nail growth cycles usually take about a month, so you typically need at least two to three weeks to notice any visible results from using nail strengtheners. Be consistent in applying them and combine them with proper diet and daily care for the best results.
6. Recommended Nail Care Products and Tools
To help you better care for your nails, here are some international brand products I highly recommend, which have proven effective for nail care.
