For a lot of people in the UAE, a pool isn't an occasional holiday treat, it's a regular part of life, at home, at the gym, or at a friend's place most weekends of the year. And if you have curly hair, you've probably noticed the same pattern every time: your curls come out of the water feeling stiff, straw-like, and duller than before you got in, sometimes for days afterward. That's because chlorine in swimming pools can damage curly hair by breaking down protein bonds and stripping away natural oils, which leaves curls drier, more porous, and more brittle than straight hair tends to be.
This isn't your imagination, and it isn't something you have to accept as the price of swimming regularly. With the right steps, like wetting your hair before you swim and using a leave-in conditioner, you can cut down a lot of that damage. Below, you'll find exactly how chlorine affects curly hair, why curls are more vulnerable, what the green hair myth gets wrong, what to do before and after pool time, and a simple pool-day routine using Zaphira Nature products to help keep curls healthy, especially if you're swimming often in the UAE where pool water and hard water can both work against your hair.
What chlorine actually does to your hair?
Chlorine is added to pool water as a disinfectant; as a chemical disinfectant and strong oxidizing agent, it breaks down organic material, including bacteria and algae, through a chemical reaction. The problem is that hair, being made of protein, is also organic material, and chlorine doesn't distinguish between what it's meant to disinfect and the keratin protein structure of your hair.
When chlorinated water sits on and penetrates the hair shaft, it can break down some of the same protein bonds that give hair its strength and structure. Over repeated exposure, this shows up as increased porosity, with the hair cuticle lifting in the same cuticle-lifting, moisture-losing structural change covered elsewhere in our porosity content, along with genuine protein loss that leaves hair feeling rough, brittle, and prone to breakage.
Chlorine is also drying in a more direct way. It strips natural oils from the hair shaft and scalp, and repeated exposure can also cause colour fading in colour-treated curls. Because curly hair is naturally drier and more porous than straight hair, those harsh effects show up faster: curls have a harder time moving sebum down each strand, so chlorine leaves them drier and more prone to breakage. A single swim can undo weeks of careful moisture-building work if the hair isn't protected beforehand.
Why curly hair is hit harder than straight hair?
Different hair types respond differently to pool water, and the same structural vulnerability that makes curly hair more prone to dryness in general applies directly here. Curly hair's bends and coils create a more porous, more textured surface than straight hair, with more surface area and more points where chlorinated water can penetrate and linger, and the curl pattern makes it harder for natural oils to travel, leaving curls more vulnerable. Straight hair tends to shed water more easily and dry with less chlorine retained; curly hair holds onto both the water and whatever is dissolved in it for longer, which can also make it harder to preserve the natural curl pattern.
Chemically treated or colour-treated curly hair is even more vulnerable. Colour treatment already lifts the cuticle to deposit or lift pigment, leaving hair more porous and more exposed to chlorine's protein-stripping effect. If you have colour-treated curls and swim regularly without protection, the combination of two porosity-increasing factors compounds faster than either would alone.
The green hair myth, and what's actually happening
Blonde or lightened hair sometimes takes on a greenish tint after swimming, and chlorine gets blamed, but chlorine itself isn't actually what causes the green tint. The real culprit is copper, which is present in many pools either from copper-based algaecides or from copper piping feeding the pool system. Chlorine's role is more indirect, it increases hair's porosity, making it easier for that copper to bind to and stain the hair shaft. If you have lightened or very porous hair and swim regularly, this is worth knowing, since the fix (a clarifying wash, and a barrier before swimming) is the same either way.
The single most effective thing you can do: wet your hair before you swim
This is the one piece of advice that makes the biggest measurable difference, and it's also the most commonly skipped. Hair is somewhat like a sponge: if you pre wet it with fresh water immediately before getting in the pool, it absorbs that clean water first, leaving significantly less room to absorb chlorinated pool water once you're in.
Take an extra thirty seconds at a shower or tap before swimming and rinse hair completely, or fully saturate hair with fresh water before you get into the pool; a spray bottle can help if a shower or tap isn’t convenient. This single step meaningfully reduces how much chlorine your hair actually takes on, regardless of what else you do.
Building a protective barrier with a swim cap before you swim
Beyond simply wetting your hair, pre swim protection helps protect curly hair before you get in the pool by adding a barrier between your hair shaft and the water.
Apply a conditioner generously to freshly wet hair before getting in the pool, with leave in conditioner applying as a simple prep step before swimming. Conditioner applying before swimming helps create a moisture barrier around the hair shaft. The Conditioner coats the hair shaft with conditioning agents that form a protective layer between your curls and the chlorinated water, reducing how much the pool water can penetrate and strip.
Seal with a hair oil for extra protection if you're swimming for an extended period or swim regularly. A light coating is more water-resistant than a water-based product alone, adds another protective layer and, with a swim cap, creates a stronger physical barrier against chlorine contact, helping keep curls hydrated, particularly useful before a long pool day or if you're swimming several times a week.
Consider a protective style. Braids, twists, or a bun keep hair contained, minimize exposure, and reduce tangling because there is less hair exposed to the water. This is a genuinely effective, low-effort option if you swim frequently and don't want to fully wash and restyle every single time. Braiding hair reduces tangling during swimming.
Use a swim cap and wear a swim cap to further reduce chlorine contact, especially for textured hair. If you swim in a saltwater pool, it usually has lower chlorine levels than a traditional pool, but pre-swim protection still matters.
What to do immediately after swimming?
The period right after you get out of the pool matters just as much as your preparation beforehand.
Rinse thoroughly with clean water as soon as possible, and rinse immediately after swimming to remove chlorine. The longer chlorine stays on your hair after you leave the pool, the more damage it can do. Left sitting on curly hair, pool water can wreak havoc. A prompt, thorough rinse limits this window significantly and reduces chlorine damage.
Follow with a proper cleanse, not just a rinse. Water alone won't fully remove chlorine residue or other pool chemicals. Use the Curl Cleanser after a swim to actually cleanse away chlorine and any mineral or copper residue, rather than just diluting it with a rinse. If you're in the pool often, add a clarifying shampoo now and then for a deeper cleanse, which also helps lift buildup from styling products, while a gentle co wash or gentle co option can work on lighter swim days when you want to cleanse without over-stripping.
Deep condition after regular swimming. If you swim more than once a week, build in a weekly deep conditioning treatment with the Hydrating Detangling Conditioner focused on restoring moisture and helping replenish moisture after chlorine exposure. After conditioning, detangle gently with a wide tooth comb to prevent frizz.
After swimming, minimize heat styling and avoid frequent heat tools when possible, opting for air drying or low heat instead.
Use a microfiber towel to dry hair after swimming.
Consider a barrier repair treatment for frequent swimmers. If chlorine exposure is a regular part of your routine, not an occasional summer activity, the Intense Regenerating Balm is worth incorporating weekly. It's formulated specifically for high porosity, damaged, and chemically compromised hair, exactly the profile that regular chlorine exposure creates over time, combining lipids that reinforce the cuticle with proteins that help fill the structural gaps chlorine leaves behind.
For swimmers, regular trims every 8–12 weeks help remove split ends and prevent breakage. Staying hydrated also supports a healthy scalp and healthy hair overall.
A pool-day routine using Zaphira Nature products
Before swimming:
-
Wet hair thoroughly with fresh water
-
Apply the Conditioner generously before getting in the pool to help form a barrier
-
Optionally seal with a light oil or the Serum Curl Gloss Allure, which works as a protective spray against chlorine and uv rays
-
Consider a protective style if swimming for an extended period to keep hair contained, and add a swim cap over the style for a more effective physical barrier
After swimming:
-
Rinse immediately with clean water
-
Cleanse properly with the Curl Cleanser, and rotate in a clarifying shampoo after heavy pool exposure for a deeper cleanse
-
Deep condition with the Hydrating Detangling Conditioner
-
Restyle with your usual leave-in, cream, and gel routine, using styling products in moderation so hair stays manageable without extra buildup
-
For frequent swimmers, add a weekly Intense Regenerating Balm treatment to your routine
-
Try to use less heat styling after pool days so curls defined are easier to maintain
The UAE factor
Pool access is genuinely more of an everyday reality in the UAE than in many other places, private pools, compound and building pools, and gym facilities all mean regular swimming is common rather than occasional. This makes chlorine protection worth treating as a standing part of a curl routine here specifically, not just something to think about on holiday.
There's also a compounding factor worth knowing: the UAE's hard water, already covered extensively elsewhere in our content, adds its own mineral buildup on top of whatever chlorine and pool copper residue accumulates. Swimmers here may also deal with ocean water or salt water, which can dehydrate curls differently from chlorinated pool water. If you swim regularly and also deal with hard water day to day, your hair is managing two separate sources of buildup and porosity increase simultaneously, which is exactly why the clarifying, barrier-repair approach above matters more here than it might in a climate with only one of these factors to contend with.
The Zaphira Nature approach
Regular swimming shouldn't mean choosing between an active lifestyle and healthy curls. With the right preparation before you get in the water and the right care once you're out, chlorine's impact on curly hair is genuinely manageable, not something you simply have to live with as a swimmer.
Every product in the routine above is formulated to support exactly this, protecting the barrier before exposure, and repairing what chlorine takes afterward. Consistent curly hair care also helps swimmers protect their curl pattern long term. For overnight upkeep, sleep on a silk pillowcase to reduce friction and help preserve curls.
