Frequently asked questions

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.

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.

It's 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's paired with Dead Sea minerals and botanical extracts to remove, protect and restore in one system.

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's far less damage to undo afterwards. Protect before, remove after.

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's already there.

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.
