SOOO Swim Shampoo — After-Swim Chlorine Care 500ml
A clarifying shampoo built for people who spend more time in the water than out of it. Chlorine, salt, and hard-water minerals quietly build up on hair and scalp after swimming — Swim Shampoo rinses them away without stripping the moisture that keeps lengths soft.
The formula pairs a gentle cleansing base with apple cider vinegar, aloe vera, hydrolyzed keratin, niacinamide, and a blend of plant-derived oils and peptides — chosen to leave the scalp clean and the hair smooth after every swim.
Why it works
- Lifts chlorine, salt, and mineral buildup after swimming

Hero ingredient — Apple Cider Vinegar.
What that benchmark led us to decide
Most 'swim' shampoos just perfume over the chlorine. This one carries sodium thiosulfate to neutralize it, clarifies with ACV, then puts protein, ceramide and peptides back — all on a sulfate-, silicone- and paraben-free base that screens 9.2. For anyone in the pool more than once a week, this is the swim shampoo we'd hand them first.
Swim today. Keep your hair tomorrow.
Every time you get in the water, chlorine, salt and hard-water minerals settle onto your hair and scalp. Left on, they're what turns healthy strands dry, rough and dull. Swim Shampoo is built to clear that buildup at the source — and then condition, so your hair feels soft instead of stripped. It's the wash for people who refuse to choose between the pool and good hair.

What the pool leaves behind
Chlorine is added to pool water to keep it clean — but it doesn't rinse off with plain water. It clings to the hair shaft along with salt and trace metals like copper, forming a film that builds up wash after wash.
That film is why swimmers' hair so often feels different from everyone else's. If any of this sounds familiar, it's the buildup talking:
Three things, every wash
Most shampoos only do the third part. Swim Shampoo is formulated to clear, calm and condition in one step, so you're not stacking three products after every session.
Clears the buildup
A chelating, chlorine-neutralizing base lifts chlorine, salt and hard-water minerals off the hair and scalp — the residue that plain shampoo tends to leave behind.
Comforts the scalp
Apple cider vinegar, aloe vera and centella help calm the tight, dry, itchy feeling chlorine leaves, and bring the scalp back toward its natural balance.
Softens & strengthens
Hydrolyzed keratin, panthenol and plant oils smooth the cuticle and recondition lengths, so hair is left soft and manageable — never squeaky or stripped.
The residual-chlorine test
Chlorine in water can be measured with a simple test strip. In this demonstration, pool water is dosed with the shampoo and re-tested — the residual chlorine reads as neutralized. The active behind it is sodium thiosulfate, a well-known chlorine-neutralizing agent that's part of the formula.
Pool water tests positive for residual chlorine on the strip.
Re-tested with the shampoo added, the residual chlorine reads neutralized.
A demonstration of how the formula's chlorine-neutralizing ingredient behaves in water. It illustrates ingredient action and is not a claim about hair growth, hair loss, or any medical outcome.

Bind, lift, condition
Binds — chelating and chlorine-neutralizing ingredients grab onto the chlorine and hard-water metals sitting on your hair so they can be rinsed away instead of building up.
Lifts — a gentle, sulfate-free lather carries that loosened residue off the hair and scalp without stripping the natural oils that keep hair flexible.
Conditions — keratin, panthenol and plant oils smooth and resoften in the same step, so you step out of the shower with hair that feels cared for.
Three steps
Rinse
Wet hair with clean water as soon as you're out of the pool or sea — the sooner you rinse, the less time buildup has to set.
Lather
Work a coin-sized amount through wet hair into a light lather and leave it for about a minute so the actives can do their job.
Rinse out
Rinse thoroughly. Follow with conditioner if you like. Use 1–2× a week, or after every swim if you're in the water daily.
Tip: for stubborn buildup or that faint green tint on light hair, leave the lather in for 2–3 minutes before rinsing.

People who live in the water
Daily chlorine exposure that regular shampoo can't keep up with.
Gentle enough for kids coming home from swim class.
Clears salt and minerals after the sea, not just the pool.
Helps protect tone from the dulling, brassy effect of chlorine.

Clear gel, clean rinse
A light, clear gel that builds into an easy lather and rinses clean — without the stripped, squeaky finish a harsh clarifier leaves. Hair feels soft and weightless straight out of the shower.
The scent is fresh and low-key — a clean, watery note that fades fast, so it never competes with the rest of your routine. No heavy perfume.
Questions, answered
Is it really sulfate-free?
Yes. Instead of SLS/SLES, it cleanses with a gentle, amino-acid-style surfactant base. It still clears chlorine and mineral buildup — it just does it without stripping the moisture that keeps hair soft.
How often should I use it?
For most people, 1–2 times a week keeps buildup in check. If you swim every day, you can use it after each session — it's gentle enough for frequent washing.
Is it safe for color-treated hair?
Yes. It's formulated to be gentle on color while it clears chlorine and minerals. Clearing that buildup is actually what helps color look truer for longer.
Will it fix the green or brassy tint after the pool?
It helps clear the copper and chlorine residue that causes dull or greenish tones on light hair, so color reads cleaner. It's a clarifying shampoo, not a toner or dye — for heavy discoloration, pair it with a toning treatment.
Can kids use it?
Yes — it's a gentle, sulfate-free wash suited to children coming out of swim lessons. As with any product, avoid the eyes and rinse well.
