for anyone whose hair and skin gave up
It wasn't you.
It was the water.
The dryness, the dullness, the itch after every shower. You blamed your products. But city water carries the same disinfectant as a swimming pool, and you soak in it every single day.

the oxidant gap
City water is disinfected.
Your skin pays the toll.
Chlorine leaves with the water
The disinfectant that keeps water safe in the pipes does not switch off at your showerhead. It arrives with every shower, at pool-level concentrations.
Hot water opens the door
Warm water opens pores and lifts the hair cuticle, so the disinfectant gets easier access to skin and hair than it ever gets in a pool.
Your filter missed the real one
Over 1 in 5 American homes now get chloramine, a disinfectant ordinary carbon filters barely touch. That is why the last filter changed nothing.
the oxidant seal
Don't trap it. Convert it.
Ordinary filters are sponges: they trap a little chlorine and give up fast. The Litmus Showerhead runs a two-stage conversion core instead.
Stage one: KDF-55 and calcium sulfite neutralize free chlorine on contact, at shower temperature and full pressure.
Stage two: a dedicated Vitamin C stage takes apart chloramine, using the same chemistry cities themselves use to de-chloraminate water.

Filter does not soften water or remove dissolved minerals (calcium and magnesium). Cosmetic benefits (softer-feeling hair and skin) reflect reduced chlorine exposure. Individual experiences vary.
