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. This isn't your imagination, and it isn't something you have to accept as the price of swimming regularly. Here's exactly what chlorine does to curly hair, and how to actually protect against it.
What chlorine actually does to your hair?
Chlorine is added to pool water as a disinfectant, and it works by being a 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, 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, which matters more for curly hair than any other hair type, since curly hair already struggles to distribute what little natural oil it produces down the length of each strand. 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?
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. 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.
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, it can only absorb so much liquid. If you thoroughly saturate your hair with clean, chlorine-free water immediately before getting in the pool, your hair 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 get your hair completely wet, not just damp, all the way through to the scalp. This single step meaningfully reduces how much chlorine your hair actually takes on, regardless of what else you do.
Building a protective barrier before you swim
Beyond simply wetting your hair, applying a leave-in product before swimming creates an additional physical barrier between your hair shaft and the pool water.
Apply a leave-in conditioner generously to freshly wet hair before getting in the pool. The Leave-In Conditioner coats the hair shaft with a layer of moisture and conditioning agents that sit between your curls and the chlorinated water, reducing how much the pool water can penetrate and strip.
Seal with an oil-based product for extra protection if you're swimming for an extended period or swim regularly. A light coating of oil is more water-resistant than a water-based product alone and adds a further layer of defence, 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 tuck away more of your hair's surface area, meaning less total hair is directly 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.
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. The longer chlorinated water sits on your hair after you leave the pool, the more time it has to continue its drying, protein-stripping effect. A prompt, thorough rinse limits this window significantly.
Follow with a proper cleanse, not just a rinse. Water alone won't fully remove chlorine residue. 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.
Deep condition after regular swimming. If you swim more than once a week, build in a weekly deep conditioning session with the Hydrating Detangling Conditioner specifically to counteract the cumulative protein and moisture loss that regular chlorine exposure causes over time.
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.
A pool-day routine using Zaphira Nature products
Before swimming:
-
Wet hair thoroughly with clean water
-
Apply the Leave-In Conditioner generously
-
Optionally seal with a light oil or the Serum Curl Gloss Allure, which also offers UV protection, a genuine bonus given how much sun exposure typically comes with pool time
-
Consider a protective style if swimming for an extended period
After swimming:
-
Rinse thoroughly with clean water as soon as possible
-
Cleanse properly with the Curl Cleanser
-
Deep condition with the Hydrating Detangling Conditioner
-
Restyle with your usual leave-in, cream, and gel routine
-
For frequent swimmers, add a weekly Intense Regenerating Balm treatment to your routine
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. 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.
