Weak Fingernails Causes, Meaning, How to Fix (Home Treatment)

Are you concerned about paper thin, weak fingernails and associated symptoms such as hair loss? Your diet (nutrition) could be to blame but beyond dietary deficiency of minerals and vitamins, there are other causes of weak, peeling fingernails – sometimes with ridges – ranging from benign to more serious. Continue reading to discover not only not the common causes but also how to fix weak fingernails at home.

What Does Weak Fingernails Mean?

For seniors, weak fingernails that feels soft and easily chip, crack, split, or peel may simply be a sign of ageing. Nails get progressively brittle as we grow older, says the NYU Medical Center and is indeed the most common cause of this nail problem.

For young people, however, soft, weak fingernails and toenails often means that you have been exposed to factors that impacts on the structural integrity of the nails. The Medicine Net identifies two major factors: exposure to harmful chemicals and products or an underlying medical condition.

What Causes Thin, Weak Fingernails

To better understand how to fix weak fingernails, it is perhaps better to highlight the most common causes of this nail condition. That way you will be better equipped to not only treat the problem but also prevent its re-occurrence:

  • Nutritional deficiency: According to the WebMD, low dietary intake of vitamins such as “folic acid and vitamin B-12 can cause weak, ridged, and even peeling nails”. Inadequate intake of protein and essential minerals such as iron, calcium, zinc, copper and selenium can also cause weak fingernails and in some cases, hair loss.
  • Longterm use of nail polish: If you have been using nail polish for quite some time, it may explain why your fingernails are thin and weak, says the MedicineNet. This is especially true if you use nail polish removers with acetone as they dry and weaken the fingernails and toenails.
  • Excessive exposure to moisture: Spending lots of time working with water e.g. dishwashing, swimming, etc. can also cause weak fingernails.
  • Exposure to harmful chemicals: From paints to thinners and certain detergents, these harsh chemicals can cause weakening of fingernails and other symptoms associated with nail disorders e.g. splitting, cracking, peeling etc. Alcohol-based sanitizers are also often harsh to the nails.
  • Dryness: Just as excessive wetness, very dry environment can be harmful to fingernails.
  • Medical conditions: According to the MedlinePlus, thin, weak nails and hair are among the early symptoms of hypothyroidism (hair loss is also common). Anemia, Lichen planus, anemia, fungal infection (notable for yellowing of the affected nails), alopecia areata, and eczema can also cause weakening of fingernails and associated symptoms include among others. In case of chronic soft fingernails, seek medical attention to rule out these diseases.
  • Have weak fingernails with ridges? Then your genetic makeup may be to blame; heredity is thought to play a role in nail ridging (vertical). According to the Mayo Clinic, vertical ridges (from the tip of the nail downwards) are typically harmless but horizontal ridges (running across the nail) are usually a sign of health conditions ranging from malnutrition to heart and respiratory conditions.
  • Weak, brittle nails may be one of the symptoms of menopause. This is largely attributed to hormonal (especially estrogen) fluctuations and the corresponding fluctuation in fluid balances in the body.

The American Osteopathic College of Dermatology suggests an easy way to tell if you are dealing with an internal (e.g. vitamin deficiency) or external factor (e.g. harsh detergents): if you have weak fingernails but strong toenails, high chances are that you are dealing with an external factor rather than internal factor.

Weak Fingernails Treatment – How to Fix Soft, Weak, Peeling Fingernails and Toenails

Thin, weakened nails that crack, split, or peel easily steal from the aesthetic appeal of the nail that every woman desires. Luckily you can effectively strengthen soft fingernails with nothing more than simple home remedies that are affordable and easily available – you could even have them in your house already. Below is a guideline on how to strengthen weak fingernails at home:

Take Biotin Supplements

The MedicineNet recommends biotin (a vitamin) supplementation can help to strengthen and fix thin, weak fingernails. A study published in the Journal of Cutis showed a 25% nail thickness increase after supplementation with 2.5 mg of biotin over a period of six months.

The American Osteopathic College of Dermatology suggests you “Get the “Biotin ultra” 1 mg. size as it also comes as much smaller pills and take 2 or 3 a day. It takes at least 6 months, but does really help at least 1/3 of the time.” It however cautions against using biotin pills during pregnancy.

Watch Your Diet

Including essential nutrients and vitamins can also help to fix weak fingernails. Below are some dietary considerations:

  • Include lots of biotin-rich foods such as whole grains, liver, lettuce, egg yolk, cauliflower, soybean, fish, lentils, bananas, avocado, and milk in your diet.
  • The WebMD recommends eating more cold cereals, beans, and whole grains as these are extra rich in vitamins especially folic acid.
  • Avogel recommends taking foods rich in magnesium to increase your body’s ability to absorb calcium. You will want to add foods such as whole grains, dried fruits and seeds, and nuts.

Use Nail Hardeners

Nail hardeners can as well help strengthen and fix weak fingernails but choosing the right product is key to effective treatment. The WebMD suggests looking for nail hardeners formulated with nylon or sulfhydryl protein. A product that contains these two ingredients is even better.

What about formaldehyde and calcium based nail hardeners? Although they also do the job, the WebMD says that they often harden the nail too much that it become susceptible to cracking.

Moisturize Your Fingernails Frequently

Burt’s Bees Lemon Butter Cuticle Crème is also popular among skin care experts and bloggers.

Simply apply the product of your choice directly on your fingernails or toenails regularly. For an even more powerful weak fingernail treatment regimen, the WebMD suggests applying a moisturizer on the nails at night and then sleeping with a pair of cotton gloves or socks (for toenails).

Massage Your Nails

Massaging your fingernails and toenails can help treat them naturally by increasing blood flow to them.

When washing dishes, gardening, cleaning, or doing any other task that involves getting into contact with water and harsh detergents or chemicals, get a pair of rubber gloves with cotton lining on.

Apply Nail Polish (But Appropriately)

Whaaat! I know it sounds counterproductive but as the WebMD says, nail polish helps to slow down evaporation of water from the fingernails and may be worth your effort if you have not been using nail polish.

They are however quick to emphasize that you should not use nail polish all that often nevertheless. You should re-apply at intervals of not more than one time each week.

Caution: If you think nail polish, lacquers, adhesives, or any other nail care and beauty product is responsible for weakening of the fingernails or toenails, avoid using it for a while to see if the condition improves.

Use Appropriate Nail Polish Removers

To effectively fix weak nails, it is advisable to completely avoid traditional products that contain acetone. Acetone strips the nails of their oils and moisture, making them dry and weak. Instead, look for acetone-free polish removers e.g. soy-based products the likes of Priti NYC.

File Properly

How to Prevent Weak Fingernails and Toes

  • Avoid acetone-containing nail polish removers.
  • Apply a moisturizer every time you wash your hands or finish working with water or harsh detergents.
  • Drink plenty of fluids to keep your overall body hydrated.
  • Apply lotion to your fingernails before applying nail polish: According to Ellen Marmur, MD, associate clinical professor of dermatology at Mount Sinai, NYC, applying lotion helps to “fill in microscopic gaps in the nail, like a primer, and hydrate it so it’s not as susceptible to damage from what you put on after.” Allow the lotion to dry in (or wipe off the excess if any), then apply your polish as usual.
  • Stay away from alcohol-based hand sanitizer products.
  • During manicure, skip soaking your nails in water.
  • Avoid biting your fingernails or pick at your cuticles, says the Mayo Clinic.
