Chlorine is not a mineral, but an oxidizer. Chlorine is put into drinking water and swimming pools to kill bacteria. Active chlorine in the hair can cause it to feel gummy when wet, and straw-like & brittle when dry.  It also causes your hair to lack shine.

Chlorine can discolor hair, no matter if it's natural color, or hair that's colored.

Copper is a mineral that bonds strongly to the hair shaft. It gets on your hair from underground water, particles from copper water pipes, or copper sulfates added to pool & drinking water to control algae growth. Oxidized copper discolors light hair, producing a green tint, and causes dark hair to tint even darker, especially on the ends. It can also weigh hair down.

Chlorine and minerals attach to the hair from repeated exposure. This builds up over time, creating a "wall" of minerals on your hair's protein that will prevent penetration of color, perms, and straighteners.
