There are several reasons why gel nail polish turns black. One reason could be exposure to UV light, which causes photochromic pigments in the polish to undergo a chemical reaction, resulting in a change in molecular structure and, consequently, colour. Another reason could be the transfer of dye from clothing or bed linen; this is more likely to occur with dark-coloured fabrics and can be tested by wearing only light-coloured clothes for a few days. Additionally, food with high acid content or certain spices such as turmeric, ghee, and tamarind can cause discolouration. Other potential causes include exposure to chemicals in cleaning supplies, cosmetics, or self-tanners, as well as smoking.

What You'll Learn
Exposure to UV light
UV light exposure can also cause discolouration in regular nail polish. The special pigments in nail polish react to UV light or temperature changes, resulting in colour alterations. This is due to the thermochromic pigment, which is sensitive to temperature variations. When nails are at a lower temperature, the nail polish appears as one colour. However, as the temperature increases, the pigment reacts and changes colour. This reaction is reversible, and the colour will change back when the temperature decreases.
It is important to note that overexposure to UV light is possible, and this can lead to discolouration of gel nail polish. This can occur if you spend a significant amount of time in the sun or use self-tanners. Discolouration due to overexposure to UV light will vary from person to person, as everyone tans differently. Additionally, smoking can also cause discolouration, as the chemicals in cigarettes can alter the colour of the gel, especially on the dominant hand.

Interaction with chemicals
It is important to note that the discolouration may not be limited to the nail polish itself, as some individuals have reported their actual nails turning black. While the exact cause of this discolouration may vary, it is likely due to a combination of factors, including the type of gel nail polish used, individual exposure to certain chemicals, and personal habits such as smoking or sun exposure.
To prevent gel nail polish from turning black, it is recommended to minimise direct contact with chemicals and intensely coloured substances. This includes avoiding exposure to cleaning supplies, cosmetics, and dark-coloured dyes in clothing or other materials. Additionally, proper nail care and the use of a top coat can help protect the nail polish and prevent discolouration.
In some cases, the discolouration may be temporary and can be removed with nail polish remover or rubbing alcohol. However, it is important to act quickly, as the stain may become more difficult to remove if it sinks to the next layer of the nail polish. It is also recommended to avoid using acetone-based products, as these can be harsh on the nails and skin.
While the exact cause of gel nail polish turning black may vary depending on individual circumstances, it is clear that interaction with chemicals plays a significant role in the discolouration process. By understanding the potential triggers and taking preventive measures, individuals can better maintain the desired colour and longevity of their gel nail polish.

Contamination with a different colour
One of the reasons for gel nail polish discolouration is contamination with a different colour. This can occur when the gel polish is exposed to UV light, such as a UV lamp during the curing process, or even from overexposure to the sun. The photochromic pigments in the polish undergo a chemical reaction, changing their molecular structure and, consequently, their colour. This is similar to how smoking causes teeth to turn yellow—the same process happens to your nails, especially the dominant hand.
Additionally, certain ingredients in cosmetics or cleaning agents can cause discolouration. This is due to a chemical reaction with the gel nail polish. It's also important to consider the products you use on your hands, as some dyes in lotions or hair products can transfer and stain your nails. Clothing can also be a factor, especially if it's a new, dark-coloured garment that may rub off on your nails.
To prevent contamination and discolouration, it's recommended to clean your nail polish brush regularly and be mindful of potential sources of colour transfer in your environment, such as new clothing or hair dye.
If you do experience discolouration due to contamination, you can try using nail polish remover or rubbing alcohol to gently remove the stain. It's important to act quickly, as the longer the stain sits, the more difficult it may be to remove.

Interaction with food
While it is uncommon for the chemicals in food to directly cause gel nail polish to turn black, it is possible for food to indirectly cause discolouration. This can occur when food with a high acid content, such as tamarind, reacts with the gel nail polish. In addition, highly staining foods such as turmeric can also lead to discolouration.
It is important to note that the dominant hand is usually more susceptible to discolouration, as it is more frequently used in activities such as writing, cooking, and eating. This increased contact with potential staining agents can lead to a higher chance of discolouration.
To prevent discolouration caused by food, it is recommended to wear gloves when handling highly staining or acidic foods. Additionally, washing hands immediately after cooking or eating can help reduce the risk of discolouration. In some cases, nail polish remover can be used to remove stains, but it is important to use it sparingly to avoid damaging the gel polish.
While food can be a contributing factor to gel nail polish discolouration, it is also important to consider other potential causes. These can include exposure to sunlight or UV light, low-quality nail polish, smoking, and contact with harsh chemicals found in cleaning supplies, hair dye, or skincare products.
To maintain the colour and quality of gel nail polish, it is recommended to use quality products, reapply a top coat regularly, and protect the nails by wearing gloves during activities that involve harsh chemicals or staining agents.

Interaction with clothing
While there are several reasons why gel nail polish may change colour, one of the most common causes is interaction with clothing. This typically occurs when the dye from dark-coloured clothing rubs off onto the nail polish, causing it to turn black or take on a different shade. This is particularly noticeable on the tips of the nails and the thumb, index, and middle fingers, which are more likely to come into direct contact with fabric.
Several factors can contribute to this issue. One factor is the type of fabric used in the clothing. For example, dark-wash or new blue jeans are known to transfer dye easily, as are certain types of black lace skirts. Another factor is the use of lotions or moisturisers, which can further facilitate the transfer of dye onto the nails. Additionally, some users have reported that their nail polish changed colour after coming into contact with their black bedspread, indicating that the dye from bedding can also affect nail polish colour.
To prevent this issue, it is recommended to avoid direct contact between dark-coloured clothing and freshly painted nails. This may involve choosing light-coloured clothing for a few days after painting your nails or wearing gloves while handling dark-coloured items. Additionally, avoiding the use of lotions or moisturisers that can facilitate dye transfer can also help reduce the likelihood of colour transfer onto the nails.
While clothing dye is a common culprit, it is worth noting that other factors, such as exposure to sunlight, self-tanners, or cigarette smoking, can also contribute to nail polish discolouration. Therefore, it is advisable to be mindful of various potential causes and take appropriate precautions to maintain the desired nail polish colour.
