How often do your valued clients complain about cracks in nails at your beauty salon or office? Depending on the real cause, cracking or splitting can be described in slightly varying ways.

Dry Splitted Cracked Nails
- Nail splitting (onychoschizia) can occur at its edges when the layers of the nail plate virtually split into two leaving some kind of thin space in between
- Anyone can experience and get vertical or horizontal split nails
- Cracking can affect the whole nail layer where a thin line forms along the vertical tiny ridges occurring on toe or fingernail
Cracking or splitting can be embarrassing and a shameful thing. But why does it occur? Read on to learn more about remedies, treatments, cracked nail repair and what to do if they are splitting.
Causes or reasons splitting toe and fingernails
What causes this problem? We have insightful causes to help you learn more about cracking or splitting. While some causes directly lead to them cracking a few factors may cause this problem indirectly. Let us discuss the various possible causes
Trauma
Trauma can result from repeated injury to your hands or the fingers themselves. Some of the common ways of trauma from physical injury include:
- A hard blow
- Habitual nail-biting
- Picking at them l with another nail or some cruel tools
- Scratching using sharp tools
- Getting used to opening lids using them
- Ground digging especially for kids or children
Nail trauma normally leads to painful experiences, especially during handling or washing. Common signs include:
- Throbbing pain
- Cracking or splitting
- In severe damage cases, they can separate from its bed
- Abnormal color (dark) or hematoma
- The toenails may sometimes become thickened
Exposure to harsh chemicals or care products
Bearing in mind the permeability or ability to quickly absorb, exposing them to chemicals or products with damaging potential can cause splitting.
These chemicals or products include household cleaners, nail polish including polish removers.
Lichen planus

Lichen Planus can also cause cracked nails
Another cause of splitting nails both on fingers and toes is lichen planus. There is a possibility of lichen planus to develop on one part of the body or multiple areas including (in the mouth or on arms or nails or genitals, etc.)
Symptoms may vary greatly according to the areas or part of the body that is affected. If the skin is involved some of the signs or symptoms include:
- Plaques or patches on the skin
- Redness irritation
- Formation of bumps
- Itching
- Pain in the genitals
- Tiny dots in mouth
Besides splitting, thinning of the nails can occur. If your finger or toenails are affected you are equally at risk to lose them too.
The cause of lichen planus is not clear. According to the American Academy of Dermatology, however, below are some reasons thought to bring about its occurrence.
- Certain medications such as those prescribed for patients with High Blood Pressure (HBP)
- The material used in teeth filling
- Hepatitis C
Hypothyroidism

Hypothyroidism symptoms
Studies have shown there is a close connection between manifestations in fingernails symptomatic of a problem with thyroid function. One of these is paronychia-hypothyroidism. According to Dr. Peter Osborne, classic features drawn after a diagnosis include:
- Vertical white ridges on the fingernails
- Rough cuticles
- Splitting
Besides splitting, hypothyroidism can lead to thinning brittle nails which are also a fairly considerable problem.
Vitamin deficiency
Although this is a rare ailment, a severe vitamin deficiency is sometimes indicated by this splitting or cracking.
Spots on nails or small well-demarcated lines in them is one of the possible sign of s vitamin deficiency.
NOTE: Vitamin deficiency can be a problem for toddlers, children, and adults.
Weak or brittle nails

Brittle cracked ones
Having weakened nails can easily lead to them
On the other hand, brittle ones can also be another risk factor for splitting. People whose are brittle often exhibit some of these signs.
- Peeling nails (esp. at the nail tip edges
- Nails snapping easily with little force exerted
- Slow growth
Common causes include medical reasons, malnutrition, very dry thin nails, infections or conditions such as Sjögren syndrome.
Excessive moisture
Though they require a certain percentage of moisture content, wetting them frequently makes them become weaker thus prone to cracking especially if they are longer than normal. People with naturally thinner ones tend to suffer more since this condition allows them to become soft.
Wetting through washing frequently is another reason why people end up with peeling nails.
Infections
Fungal (yeast) infections can change their texture, color or shape. If texture or shape is interfered with, splitting may occur with time if there is little done to cure such infections.
Other infections or illness causing this splitting or cracking problems include:
- Severe bacterial infections
- Viral warts
- Heart valve
- Kidney disease
Manicure
Although a nail manicure is viewed as a basic care routine, how you do it could result in cracking.
Nail psoriasis

Signs of psoriasis
As a risk factor for them splitting, psoriasis can produce varied symptoms depending on severity the condition. For instance, if you have this condition your nail growth could be suppressed, change the texture, color, cause inflammation or sometimes result in the separation of their bed from the fingers.
Furthermore, nail psoriasis can easily lead to infections that would worsen the symptoms.
Dry and cracked
Dryness in finger or toenails can lead to serious splitting especially if they are breaking often than not. Exposure to water, harsh chemicals and your regimen type can easily rob of that little moisture leading to cracked fingernails.
How to fix dry cracked ones
If there are signs of infection such as redness or streaks of red lines in the fingernails, seek the right treatment after seeing your dermatologist.

- Preventive tips such as trimming do help a lot. Ensure you leave a curving shape
- Limit use of nail polish remover if you want to stop them from cracking in the future
