What You'll Learn

Nails can thin due to overexposure to moisture or chemicals
Overexposure to moisture or chemicals can cause nails to thin and become soft and brittle. This can be a result of frequent contact with detergents, household cleaners, and nail polish remover. Other nail products, such as nail treatments, nail polish, and gel polish, can also contribute to this. Nails can absorb the chemicals in these products, and prolonged exposure can lead to thinning and other issues.
To protect your nails from these effects, it is advisable to minimize direct contact with such substances. When engaging in activities that involve these chemicals, consider wearing gloves. This creates a barrier between your nails and the potentially harmful substances. Gloves can also protect your nails from the drying effects of cold, dry weather.
Additionally, keeping your nails trimmed short reduces the surface area through which these chemicals can be absorbed. Maintaining proper nail hygiene and care routines can help mitigate the thinning of nails due to overexposure to moisture or chemicals. This includes moisturizing your nails and hands regularly, particularly after washing or any activity that may have dried them out. Look for moisturizing lotions or creams that contain lanolin or alpha-hydroxy acids, as these ingredients can benefit nail health.
In more severe cases, thinning nails may indicate underlying health issues or nutrient deficiencies. If the problem persists despite your best efforts, it may be advisable to consult a healthcare professional. They can assess your symptoms and advise you on any necessary dietary changes or supplements to support nail health.

Vitamin deficiencies can cause nails to thin
While changes in nail colour, texture, or shape can be harmless, they can also indicate a vitamin deficiency or a more serious underlying health issue.
Vitamin B12 deficiency, for example, can cause nail hyperpigmentation, which manifests as longitudinal melanonychia, diffuse bluish discolouration, and reticulate pigmentation. Similarly, vitamin D deficiency can cause nail malformations such as dimples and pinhead-sized dents on your fingernails. This is usually triggered by allergic or immune-related skin problems.
Iron deficiency is another common cause of thin nails. If you have thin fingernails that dip down in the middle and look like spoons, this could be a sign that you need more iron in your diet. A simple blood test can determine if you are deficient in iron, which can be treated with a high-strength supplement.
Zinc deficiency can also cause nail changes, although this is less common. Nail problems can also be caused by external factors such as overexposure to moisture or chemicals, including detergents, cleaning fluids, nail treatments, and nail polish or polish remover.
If you notice any concerning changes in your nails, it is important to consult a dermatologist or your primary care doctor. They can help determine if the changes are due to a vitamin deficiency or another underlying health issue.

Nails can thin with age
While changes in nail appearance and texture can be harmless, they can also indicate an underlying medical condition. Nails may become thinner with age, and conditions like psoriasis and rheumatoid arthritis can result in thicker nails. Fungal infections, which are common in older people, can cause nail thickening and discolouration. Toenails are particularly vulnerable to fungal infections because shoes create a warm, moist environment for fungus to grow.
Nail thinning can be caused by external factors such as overexposure to moisture or harsh cleaning chemicals. Incorrect product removal can also cause thinning of the nail plate, and many product removal processes can dry out the nails, making them more prone to cracking and breaking. Additionally, using nails as tools can be especially damaging to thin nails, causing them to bend and become weak.
Nutritional deficiencies, such as a lack of iron, vitamin A, B7, C, or D, can also contribute to nail thinning. In such cases, incorporating iron-rich foods into your diet and taking multivitamins that include calcium and B vitamins can help address the deficiency and improve nail health. Applying cuticle oil or lotion daily can also help moisturise and strengthen dry, brittle nails.
Genetics can also play a role in nail thinning. Some individuals may be genetically predisposed to thin nails, making it challenging to grow long natural nails. In such cases, certain nail shapes, such as round or oval nails, may be less prone to breakage than square or almond shapes. Additionally, consistently wearing nail polish can add thickness and strength to thin nails, protecting them from bending.
If you notice significant changes in your nail's texture, thickness, colour, or shape, it is advisable to consult a healthcare provider or dermatologist to determine if the changes are due to ageing or an underlying medical condition.

Incorrect product removal can cause nail thinning
While some people are genetically predisposed to thin nails, incorrect product removal can also cause nail thinning.
Picking or peeling off nail products can remove layers of the nail plate, making your nails thinner and more prone to breakage. Therefore, it is important to find a product that balances thickness with ease of removal. For instance, Lilaque Soy Gel provides thickness and protection while being easier to remove than salon gel systems.
Additionally, it is important to follow the manufacturer's instructions when removing nail products. Consistently wearing nail polish can help nails grow longer by adding strength and thickness, but it is crucial to remove the product once it starts to chip.
Nail health can also be affected by overexposure to moisture or chemicals such as detergents, cleaning fluids, nail treatments, and nail polish or remover. To prevent this, avoid having chemicals around your nails and opt for natural alternatives. Wearing gloves during water-heavy tasks or activities that may damage your nails can also help protect them.
Furthermore, using nails as tools, such as picking, prying, or scraping, can weaken and break them, especially if they are already thin and brittle. Nails can also become brittle and prone to cracking and breaking if they are too dry. Applying cuticle oil daily can help improve nail hydration and promote the growth of longer, stronger nails.

Repeated wetting and drying can worsen nail thinning
While nail thinning can be caused by various factors, such as vitamin or mineral deficiencies, overexposure to moisture can also play a significant role. Repeated wetting and drying of the nails can worsen nail thinning and make them more susceptible to breakage.
Nails that are frequently exposed to water can become temporarily soft and weak, making them more prone to bending and tearing. This is especially true for thin, brittle nails, which are already delicate and prone to breakage. The soft and weak state of the nails after exposure to water can make them more vulnerable to damage when used for picking, prying, or scraping.
To prevent nail thinning due to repeated wetting and drying, it is advisable to wear gloves while performing water-heavy tasks such as washing dishes or cleaning. This creates a protective barrier between the nails and water, reducing their exposure to moisture. Additionally, avoiding the use of nails as tools is crucial to prevent bending and weakening them further.
It is also important to consider the products used on the nails. Some nail products, such as nail polishes and removers, can contribute to nail thinning if not used correctly. Opting for products that offer a balance between thickness and ease of removal can help protect the nails while maintaining their health. Cuticle oils and lotions containing alpha-hydroxy acids or lanolin can also be beneficial in maintaining nail hydration and preventing dryness, which is another contributing factor to nail thinning and brittleness.
While nail thinning can be a cosmetic concern, it is important to be aware of potential underlying causes. In some cases, nail changes, including thinning, can indicate a vitamin or mineral deficiency, such as iron or vitamin A, B7, C, or D deficiency. Conditions like anemia, hardening of the arteries, and hormonal problems can also cause changes in nail texture. Therefore, if nail thinning is accompanied by other symptoms or persists despite taking the necessary precautions, it is recommended to consult a healthcare professional to rule out any underlying medical conditions.
