Sez you.

I've seen plenty of blonde kids (no "artificially colored hair") with
green hair from a SWIMMING POOL or SPA, but not from CHLORINE. I have
observed this in pools or spas I know to have copper added, with various
concentrations of chlorine down to ZERO. Morever, I have observed those
same kids in pools I know to have *no* copper but lots of chlorine, and
never found any trace of green.

I defy you to produce a chemical reaction of hair protein plus chlorine
equals anything green.

When hair turns green from a swimming pool, it is because of a COPPER
compound likely added as an algaecide, most commonly copper sulfate.
Not chlorine. Typically concentrated in the tips of hair by gravity
during drying, the concentration being too slight to otherwise produce a
visible effect.

You also see this effect in fingernails. You won't typically see it in
dark hair.

Kinch is a nut job, who doesn't know how to think things through.

No, you're given to foolish statements like that.
