The only thing that's in haircolor is ammonia and peroxide and those are used in cleaning agents anyway. If your scalp isnt harmed... your holding tank sure won't be harmed,, and besides,,,you dump it at LEAST once a week,,, i'd think. But rest easy on the tank part..

I don't mean to "beat a dead horse" but professional haircolor products are comprised of much finer quality ingredients than the crap we poor lay people have to buy at the drug store. If you leave it on your scalp for longer than recommended you will burn it right down to your skull and all your hair will burn off..so with that in mind I would opt for keeping it out of my tanks....but, I bet you're right about it not harming the seals, I just can't afford to have any expensive issues expecially ones that I caused myself...the ol ounce of prevention.....
