Gel nails turning yellow/brown due to cheap nail polish
Gel nails turning yellow or brown can be attributed to various factors, and while it may not be aesthetically pleasing, it is generally not a safety concern. One of the primary reasons for this discoloration is the use of cheap nail polish. Less expensive brands often lack optical stabilizers or enhancers, which are designed to prevent the yellowing effect. As a result, the polish may develop a yellowish hue after a few weeks of wear. This phenomenon is well-known among nail professionals and customers alike and is more common with certain gel polish brands.
In some cases, the yellowing may occur due to the presence of photo initiators, which are necessary for the curing process of gel products. These photo initiators ensure that the gel hardens properly, but they can sometimes lead to a yellowish tint. Additionally, the use of contaminated top coats or mixing different brands of nail polish can also contribute to the discoloration. It is worth noting that high-end and more expensive brands often incorporate optical enhancers to prevent this issue, but they may not be accessible to everyone due to budget constraints.
To address this issue, it is recommended to use a regular top coat over the affected nails to hide the discoloration. Additionally, it is advised to be cautious when choosing nail polish brands, as some may be more prone to yellowing than others. While it may not be possible to completely avoid the yellowing effect, taking these precautions can help reduce its occurrence. It is also worth noting that this issue is not limited to gel nails, as regular acrylic nails can also experience similar discoloration.
While yellowing or browning of gel nails may be unsightly, it is important to remember that it does not indicate any harm to the nails or pose any significant health risks. However, if the discoloration is bothersome, individuals can consider investing in higher-end brands that are less likely to exhibit this issue. Additionally, proper nail care and maintenance can also help maintain the aesthetics and longevity of gel manicures.

Incompatible materials such as cleaning agents or hair dye
Certain cleaning agents and hair dyes can cause gel nails to turn brown due to chemical incompatibilities. This occurs when the chemicals in these products react with the gel nail polish, leading to discolouration.
Hair dyes, especially those containing ammonia or peroxide, can be particularly harsh and cause this reaction. The cuticle, which is the protective layer of the nail, can be damaged by these chemicals, allowing the dye to penetrate and react with the gel polish underneath. This can result in not only discolouration but also weakening of the nail structure.
Similarly, exposure to certain cleaning agents can lead to gel nails turning brown. Common household cleaners, such as bleach or ammonia-based products, can react with the gel polish, causing discolouration. This reaction may occur immediately or over time, especially if the nails are not properly protected during cleaning tasks.
To prevent this issue, it is important to take precautions when handling these incompatible materials. Wearing protective gloves while dyeing your hair or cleaning can create a barrier between these chemicals and your gel nails, reducing the likelihood of discolouration. Additionally, ensuring that your nails are completely dry before coming into contact with such substances can also help minimize the risk of discolouration.
If you intend to use hair dye or cleaning agents, opt for more natural and gentler alternatives that are less likely to contain harsh chemicals. For example, plant-based dyes or organic cleaning solutions may pose less risk to your gel manicure. Consider applying a clear top coat specifically designed to protect gel nails from discolouration and chemical damage. These steps can help maintain the integrity and colour of your gel nails while allowing you to continue using these products. Remember to always patch test any new product on a small area first to ensure it does not cause an adverse reaction.

Exposure to UV light
It is worth noting that while UV light exposure is a likely cause of gel nail discolouration, other factors may also contribute. For example, the use of certain hair and skincare products, such as hair dye or exfoliating skincare formulas containing alpha-hydroxy acids (AHAs), can cause the gel polish to absorb stains and discolour. This is because gel polish is a soak-off product, making it porous and susceptible to absorbing any substances it comes into contact with.
Additionally, exposure to certain foods and ingredients, particularly those with a high acid content or staining properties, can also lead to discolouration. For example, tamarind, a common ingredient in Indian cooking, is known to stain gel nails. Other ingredients such as turmeric, ghee, and coconut oil can also leave stains if they come into contact with gel manicures.
While it is challenging to prevent all instances of gel nail discolouration due to UV light exposure, there are a few things that can be done to minimise the risk. Using higher-quality nail polish can help, as cheaper formulas are more likely to discolour. Applying a regular top coat over the gel polish can also provide an extra layer of protection. In addition, it is recommended to wear gloves when performing tasks that involve exposure to staining substances, such as cooking with tamarind or cleaning with harsh chemicals.

Exposure to certain foods with high acid content
Foods with high acid content, such as citrus fruits or dishes containing vinegar, can interact with the gel nail polish, causing it to discolour. This is particularly true for lighter-coloured gel polishes, where the discolouration may be more noticeable. In addition, highly staining foods such as turmeric, used in Indian cooking, can also lead to discolouration.
To prevent this from occurring, it is advisable to avoid direct contact between acidic foods and gel nails. This may include wearing gloves when preparing or consuming foods with high acid content. Additionally, promptly washing hands after exposure to acidic foods can help reduce the likelihood of discolouration.
If discolouration does occur, it is possible to buff away the affected surface layer of the gel polish. This process can restore the original colour of the gel nails. However, it is important to act cautiously when buffing to avoid damaging the natural nail. Consulting a professional nail technician can be helpful in addressing gel nail discolouration.

Medication side effects
Gel nails can turn brown due to a variety of reasons, including exposure to certain products, old topcoats, and underlying health conditions. While nail discolouration is often attributed to external factors, it can also be an indication of medication side effects.
Drug-induced nail disease is a condition where medications affect nail growth or structure, leading to abnormalities and discolouration. This condition is more common in individuals exposed to multiple medications and tends to affect older persons more frequently. The signs and symptoms of drug-induced nail disease depend on the specific medication and may take weeks or months to appear. The higher the dosage of the medication, the higher the likelihood of nail discolouration and other nail issues.
Medications that are commonly associated with nail discolouration include antimalarial drugs such as hydroxychloroquine and chloroquine, which can cause a brownish discolouration of the nail bed. Additionally, drugs that cause onycholysis, or the lifting of the nail plate, can also result in nails appearing white, yellow, or brown due to subungual haemorrhage. These drugs include sodium valproate (an anticonvulsant) and retinoids. Damage to the nail folds has also been associated with the use of methotrexate, ciclosporin, and antiretroviral medications.
Furthermore, certain medications can cause nail dystrophy, deformity, or other nail abnormalities. These adverse drug reactions can impact the nail matrix, the nail bed, the periungual tissue, or the blood vessels feeding the nails. While drug-induced nail disease can be concerning, it is important to consult a healthcare professional for a proper diagnosis and to determine if the medication needs to be adjusted or discontinued.
In summary, while there are several potential causes for gel nails turning brown, medication side effects should not be overlooked. Drug-induced nail disease can manifest in various ways, and nail discolouration is one of the possible symptoms. Consulting with a healthcare provider can help identify any underlying issues and guide appropriate management.
