the science

Not a mask.
A mechanism.

Chlorine doesn't just dry you out. It chemically bonds to your hair and skin. PLECOTECH™ is the technology engineered to neutralize it and lift it away, before and after every swim. It's why TRIHARD is the only 360ยฐ pre & post-swim system.

Red algae complex under the microscope
The problem

What chlorine actually does

Three things happen the moment you hit the water, and regular shampoo and body wash make none of them better.

01It bondsChlorine binds to the hair fibre and strips natural oils, leaving hair dry, brittle and rough, and skin tight and itchy.
02It greensChlorine oxidizes copper in the water, which deposits onto hair as the tell-tale green tint, worst on light or color-treated hair.
03It lingersRepeated exposure breaks down the skin barrier and leaves that chlorine smell that a normal rinse never fully removes.

How it actually works

PLECOTECH™ binds to the chlorine and copper bonded to your hair and skin and lifts them away, while 100% natural red algae lays down a protective layer that stops them bonding in the first place. One system, head to toe, before and after every swim.

1
ProtectBefore you swim, lay down the red-algae barrier that blocks chlorine from bonding.
2
ExtractStraight out of the water, lift bonded chlorine, copper and salt, without stripping.
3
RestoreReplenish the moisture and barrier chlorine takes, so the damage never sets in.

Questions, answered

Frequently asked questions

What is TRIHARD?

TRIHARD is swim-specialized care, the only complete pre & post-swim system for your hair, skin and eyes. We neutralize and remove the chlorine, copper and salt that bond to you in the pool, before and after every swim, powered by our PLECOTECH™ red-algae technology.

How is it different from a clarifying shampoo or normal body wash?

Regular products are built for a normal shower. They mask the smell or strip aggressively. TRIHARD is engineered for what chlorine actually does: it binds chemically to hair and skin. We lift it away at the source and restore the moisture barrier, instead of stripping what little is left.

What is PLECOTECH™?

It is our core technology, built around 100% natural red algae, a marine polysaccharide that binds chlorine and metal ions and lays down a protective film. It is paired with Dead Sea minerals and botanical extracts to remove, protect and restore in one system.

Why use something before I swim?

Pre-swim products lay down a protective barrier so less chlorine and copper bond to your hair and skin in the first place, so there is far less damage to undo afterwards. Protect before, remove after.

Will it fix or prevent green hair?

Yes. Green comes from copper (oxidized by chlorine) depositing on the hair, worst on light or color-treated hair. Our pre-swim step blocks it from bonding, and the post-swim step lifts what is already there.

Is it safe for color-treated and sensitive skin?

Yes. Our formulas are dermatologically tested, free from parabens, SLS and alcohol, vegan and cruelty-free. They remove chlorine without stripping color. As with any new product, patch-test if you have known sensitivities.

Do you offer subscriptions?

Yes. Subscribe & Save 15% on any product via Recharge, and skip or cancel anytime. You pick the cadence and we keep your routine stocked.

What is your shipping and returns policy?

We ship from warehouses in the US, Canada, the EU and the UK, so most orders leave from a region close to you. Every order is backed by a 30-day money-back guarantee. International customers are responsible for any customs and duties.

Are your products and packaging sustainable?

Yes. Our red algae is grown by sustainable land-based aquaculture, our formulas are reef-safe, and our packaging is made from 50 to 80% recycled plastic.

Which products do I actually need?

Start with the area that bothers you most, hair, skin or eyes, or go with a prebuilt bundle and save. Not sure? The bestsellers are the easiest place to start.
