How to Get Chlorine Out of Your Hair (Without Drying It Out)

Quick answer

To get chlorine out of your hair: rinse with clean water before you swim so the strands soak up tap water instead of pool water, then wash with a chlorine-removing shampoo (not a clarifying one) as soon as you're out, and follow with conditioner to put the moisture back. The order matters more than the products, protect first, extract second, restore third. A plain water rinse after swimming removes some chlorine, but not the part that's already bonded to the hair.

Why chlorine is so hard to rinse out

I'm a swimmer. For years I'd shower after training, scrub with whatever shampoo was in the locker room, and still walk out with hair that felt like straw and smelled like a pool deck until dinner. I assumed I was doing it wrong. I wasn't, the products were.

Here's what's actually happening. Chlorine doesn't just sit on top of your hair like dust you can rinse away. It chemically bonds to the hair fibre and strips the natural oils that keep each strand smooth and flexible. That's why your hair feels rough and looks dull after swimming, and why the smell lingers, it's not on your hair, it's in it. Plain water can't break that bond. Neither can a normal shampoo designed for a regular shower, because it was never built for this problem.

If you swim a few times a week, this compounds. The hair never fully recovers between sessions, so it gets progressively drier, more brittle, and more prone to breakage and that faint green tint (more on the green below).

The 3-step method that actually works

This is the routine I now follow every single time, and it's the one I built TRIHARD around.

Step 1, Protect before you get in (pre-swim)

Hair is like a sponge. Get it wet with clean water before you swim and it will absorb far less pool water once you're in. Take it one step further and work a Pre & Post Swim Conditioner through your hair before you put your cap on, it lays down a protective barrier so less chlorine reaches the fibre in the first place. The single biggest mistake swimmers make is skipping this step and trying to fix everything afterward. Prevention is easier than removal.

Step 2, Extract after you get out (post-swim)

As soon as you're out of the water, wash with a true chlorine-removing shampoo. This is the one non-negotiable. A chlorine-removal formula is designed to bind to the chlorine and lift it off the hair, instead of just sudsing the surface. Our Swimmers Shampoo is a post-swim product for exactly this reason, it does its job after exposure, neutralising the chlorine and the smell rather than masking them. Don't reach for it before you swim; that's the conditioner's job.

Step 3, Restore the moisture (post-swim)

Removing chlorine is only two-thirds of the job. Chlorine left your hair stripped, so the last step is putting the moisture back. Condition again after shampooing, the same Pre & Post Conditioner works here, with Argan oil, Vitamin B5 and Shea to soften and smooth. Skip this and your hair will be clean but still dry. Do it and it'll feel like hair again.

That's the whole system: condition to protect, shampoo to extract, condition to restore. We bundle the two products that do it as The Hair Comb-O because they're meant to work as a loop, not in isolation.

Why not just use a clarifying shampoo?

This is the most common swap people make, and it backfires. Clarifying shampoos are built to strip everything, product buildup, oils, minerals, with no plan to put anything back. Used after every swim, they leave already-chlorine-stripped hair even drier and more brittle. A chlorine-removal shampoo is targeted: it lifts the chlorine and metals, but it's formulated to hydrate at the same time. You want removal, not demolition.

What about green hair?

If your hair has ever turned faintly green after swimming, the chlorine isn't the direct culprit, copper is. Pools contain trace copper (from pipes and some algaecides), and chlorine oxidises that copper onto your hair, where it deposits as a green tint. It shows up most on light, blonde, or colour-treated hair. The fix is the same routine above: a protective barrier before you swim means less copper binds in the first place, and a proper post-swim wash lifts what does. We wrote a full breakdown in Why does my hair turn green from swimming? if that's your main concern.

This isn't just for competitive swimmers

I built TRIHARD as a triathlete, but the people who need this most aren't only athletes. If you own a pool, take your kids to swim lessons, sit in a hot tub, or spend a week at a water park, your hair is taking the same chlorine hit, often without the daily-rinse habits a lap swimmer builds. The routine scales down: even just rinsing with clean water before you get in and using a chlorine-removal shampoo afterward makes a visible difference for occasional swimmers.

How is TRIHARD different?

TRIHARD is the only swim-care brand built around both pre-swim protection and post-swim removal, a 360° system rather than a single bottle. Every formula is dermatologically tested and powered by PLECOTECH™, our patent-pending technology built on a ratio of 100% natural red algae, Dead Sea minerals, and botanical extracts that neutralise and remove chlorine instead of masking it. The products are made in the USA, use 50% recycled-plastic packaging, and are trusted by the largest roster of supporting athletes in the category.

FAQ

How do I remove chlorine from my hair without a special shampoo? Rinse with clean water before swimming, then wash promptly afterward and condition. It helps, but a regular or clarifying shampoo can't break the chlorine bond the way a dedicated chlorine-removal shampoo does, so expect partial results.

Does rinsing with water after swimming remove chlorine? Partly. A rinse removes surface pool water, but not the chlorine that has already bonded to the hair fibre. That bonded portion is what causes the dryness, dullness, and smell, and it needs a chlorine-removal wash to lift it.

Should I use the chlorine-removal shampoo before or after swimming? After. TRIHARD's Swimmers Shampoo is a post-swim product, it removes chlorine once you're out. For before swimming, use the Pre & Post Conditioner to lay down a protective barrier.

How often should I wash my hair if I swim every day? Wash after every swim to remove the chlorine, but always re-condition to replace the moisture you've stripped. Daily chlorine removal without re-hydrating is what leaves frequent swimmers with brittle hair.

Will this help my kids' hair after swim lessons? Yes, the same protect-then-remove logic applies. Rinse them with clean water before the lesson and wash afterward. TRIHARD also makes a dedicated kids' line formulated for younger swimmers.
