Chlorine is well-known for its ability to kill bacteria and keep pool water safe. However, it can also be harsh on your nails, causing them to weaken, peel, and break. This is because chlorinated water can dehydrate your nails, stripping them of their natural oils and causing discolouration. So, what does this mean for gel nails? Gel nail polish is known for its durability and ability to repel water. But does this mean it can stand up to chlorine?

What You'll Learn

Chlorine lifts gel nails
Gel nails are porous, and while they repel water, the areas between the polish and cuticles and the undersides of the nails can still absorb water. This absorption leads to lifting and chipping, especially around the edges. Chlorine exposure can also soften and discolour gel nails, causing staining, especially in lighter shades.
To prevent this, it is recommended to wear gloves while swimming or to apply a protective base coat and non-breathable nail polish. A high-performance base coat, combined with a top coat, creates multiple cured layers that protect the nails from water damage. Additionally, it is essential to restore nail moisture after swimming by using hand creams with hydrating ingredients or cuticle oils with essential oils and antioxidants.
Some gel nail products are specifically designed for those who frequently come into contact with water, such as Calgel and Iz Gel, which may be more suitable for swimmers.

Chlorinated water dehydrates nails
Chlorinated water can be extremely harsh on your nails. Nails are a very sensitive part of the body, and they can easily absorb water, which contributes to the weakening of the bonds in your nails over time. Chlorinated water can induce similar nail changes as regular water exposure, but it is often even more severe because chlorine can strip your nails of the natural oils that keep the cuticles hydrated. This can cause your nails to become dehydrated, leading to brittleness, splitting, peeling, and breakage.
Chlorinated water can also soften and discolour gel nails. While gel nail polish repels water, keeping chlorine out, the areas between the polish and cuticles and the undersides of the nails can still absorb water, leading to lifting and chipping on the edges. A top coat can help seal out water, but it may not be enough to protect your nails from the effects of chlorine.
To protect your nails from the damaging effects of chlorinated water, it is recommended to always wear a protective base coat and non-breathable nail polish. Applying a thin layer of petroleum jelly, such as Vaseline, before swimming can also create a protective barrier between the pool water and your nails. After swimming, it is important to restore your nails' moisture levels with a nourishing cuticle oil or a hand cream containing moisturising ingredients.
Overall, while it is possible to take steps to protect your nails, chlorinated water can still be very harsh and dehydrating, leading to various types of nail damage.

Chlorine softens and discolours gel nails
Chlorine is known to be harsh on nails. Nails are very sensitive and can absorb water, which contributes to the weakening of the bonds in your nails over time. Chlorinated water can induce similar changes as regular water, but it is often even more damaging because chlorine can strip your nails of the natural oils that keep the cuticles hydrated. This can cause nails to become dehydrated, leading to brittleness, splitting, peeling, and breakage.
Gel nails are porous, and this is why they may become stained or discoloured after extended wear, especially after frequent exposure to chlorine. Chlorine can also soften gel nails, and this may cause them to lift or chip. However, this does not happen in the same way as with regular nail polish because gel polish repels water. The only places where the nail comes into contact with water are the areas between the polish and the cuticles and the underside of the nails. Since these areas can still absorb water, it could account for lifting and chipping on the edges.
To prevent chlorine from damaging gel nails, it is recommended to wear gloves while swimming or to apply a protective base coat and non-breathable nail polish. A high-performance base coat is an essential first step for nail colour application because it is the layer that directly contacts the nail. Combining it with a top coat will provide several cured layers between the nail and the water, which is helpful in keeping nails protected.
Additionally, it is important to restore the moisture of the nails and skin after swimming in chlorinated water. A hand cream containing ceramides, hyaluronic acid, or lanolin can be used to draw in and trap moisture. Alternatively, a cuticle oil formulated with essential oils and antioxidants can be applied to protect and boost hydration.

Chlorine damage prevention
Chlorine is an essential chemical that keeps swimming pools free from bacteria and infections. However, it can have some negative side effects on the skin, hair, and nails. Chlorine can strip the skin of its natural oils, causing dryness, itchiness, and irritation, which can lead to premature aging and acne. It can also cause discolouration and fading, similar to what happens to bathing suits.
To prevent chlorine damage to your nails, it is recommended to use a strengthening top coat, especially if your nails are dry and brittle. Products like Sally Hansen's Advanced Hard As Nails Strengthening Top Coat can protect your nails from chipping, fading, and discolouration caused by chlorine exposure.
Additionally, choosing the right type of gel nails can make a difference. Some products, such as Calgel and Iz Gel, are known to be more suitable for those who spend a lot of time in the water. These gels are designed to withstand constant exposure to water and prevent lifting or softening of the gel nails.
It is also important to practice proper aftercare. Washing your hands with soap and water immediately after swimming can help remove any chlorine residue and reduce its adverse effects.
Lastly, opting for outdoor pools over indoor pools can also reduce chlorine exposure. Indoor pools are enclosed spaces where chlorine can spread into the air and be inhaled, potentially causing respiratory issues and triggering asthma.
