There are many stories about nails going around — but what’s really true, and what should you do or avoid to keep your nails healthy and beautiful? Find out here.
White spots? Not a calcium deficiency!
Many people believe that white spots on the nails are a sign of calcium or zinc deficiency. In reality, they are usually caused by small bumps or injuries. Nails are delicate, and even a light knock can leave a white mark. This can happen due to:
- A nail getting caught (in a door, for example)
- Too much pressure during a manicure
- An allergic reaction to nail polish
- Frequent cutting or filing
- Nail biting
- Contact with harsh cleaning products
These spots form early during nail growth — about six weeks before they become visible — and will disappear naturally as the nail grows out. Want to prevent them? Be kind to your nails: use a nourishing hand cream and wear rubber gloves while cleaning.
Note: If you notice white spots along with grooves, dents, or pitting, this could indicate an infection. Consult your doctor in that case.
What are nails made of?
Like hair, nails are primarily made of keratin — a protein that provides strength. A healthy diet rich in vitamins, proteins, and minerals is essential for strong nails and shiny hair.
Can nails breathe?
Although often claimed, nails don’t “breathe” like skin does. Still, nail polish and artificial nails can disrupt their natural condition. They dry out the nails, make them brittle, and reduce their resistance to infections. So give your nails regular breaks and nourish them well.
Contrary to what many nail polish and artificial nail providers claim, it’s important for nail health that they’re exposed to oxygen. If this process is hindered, nails are more prone to infection, dryness, and weakness.
Stressed? Your nails feel it too
Chronic stress affects your entire body — including your nails. It slows growth and weakens the nails. Prioritize rest, healthy eating, and regular relaxation.
The important role of cuticles
Cuticles protect the nail’s growth area. Never cut them! Instead, care for them daily with a hand and nail cream. If they’re dry or hard, soften them first with cream and gently push them back using a rubber cuticle stick. Avoid hard tools, as they can damage the nail base.
Loose skin? Trim it carefully to avoid infection.
What do ridges in your nails mean?
Vertical ridges are common and usually harmless — especially with age. They’re often caused by nail dehydration. Horizontal ridges, on the other hand, often signal damage to the nail root (from an impact, for example). They may fade or remain visible.
Deeper horizontal ridges can be a sign of vitamin deficiencies or conditions like psoriasis or arthritis. Not sure? Consult your doctor.
Want smoother nails? Gently buff them to remove a fine layer and reveal a more even, shiny surface — no nail polish needed.
Try the Parocare polishing block:
- Blue file: once a month for smoothing
- Grey file: twice a month to remove irregularities and stimulate circulation
- White file: to add a natural shine
Brittle nails? Common causes
- Do your nails break easily? That may be due to a mix of genetics and daily habits. Common culprits include:
- Washing dishes or cleaning without gloves
- Working with paper
- Overusing hand sanitizers
Take good care of your hands. Apply a nourishing hand and nail cream several times a day. And: only clip nails if you want to shorten them drastically — instead, file them into shape with a fine glass or cardboard file. Always file in one direction to prevent cracking.
Nutrition also plays a key role. Deficiencies in silica, calcium, zinc, B vitamins (especially biotin), and vitamin D can lead to brittle nails. Eat a balanced diet, manage stress, and get enough sleep.
Five tips for stronger nails
- Hydrate your nails with a good hand and nail cream — don’t forget your cuticles!
- Buff regularly for a natural shine and to prevent splits.
- Protect your nails from water; wear gloves when doing household chores.
- Avoid acetone-based nail polish removers — they dry out your nails.
- File instead of cutting to prevent cracks and splits.
