How often can it be used?

As long as you have a good conditioner afterwards, (I strongly recommend ''Szhwarzkopf Professional Blond Me Brilliance Intense Treatment''), you can use it as much as you need to make your hair look the way you want. You'll know. Just try it till you know how you like it. Everyone's hair is different.

It depends on your hair colour I would, say or if your hair pulls in colour very quickly. It will leave a purple hue if left on too long but it washes out next wash. I use it three times a week, just a small amount and rinse it out immediately after applying. It is great for removing brassiness or yellowness from blonde hair. hope this helps

my friend who knows about thes things say not to use it every day or my hair which is grey will turn purple. so i use it 3=4 times per week.

I didn't use it for its original purpose, so I don't know how long it lasts. I suppose it depends on how much and how often you use it.

I use it every other watering, so about every other week, but that is just based on my needs and there are probably a bunch of variables that would determine how often you would want to use it. I know certain plants recommend more or less frequent fertilizing.

Yes it can be used over and over again. Just make sure the parts you put in don't have paint, plastic or gaskets still on or they will be dissolved. Also can be used on any metals needed cleaned.

that depends on usage, every other day unless you are a heavy user. Than once a day.

You use it as little as once per month or as much as once per week , depending on your need.

It depends on use. In substantial use, a few days.No use, or little use: few weeks.It last far more than its competition

The unit has a shelf life. At 24/7 it might get used up more quickly than you would like.

It depends upon your environment. I wouldn't do it everyday maybe...twice a week? One or two spritz?

You can use it as many times as you want. The battery is the only thing that needs to be replaced. My battery lasted roughly 2 months of HEAVY usage. The device will let you know that the battery is low when maybe 5% charge is remaining.

My dental hygienist told me I could use it as much as I wished but shouldn't need to use it very often. Currently I probably use it monthly, definitely not daily or weekly. But I was never told about a any time restrictions.

We've only used it once so far. We used it at the end of October 2013. I was told by a plumber to use it every 18 months. Hope that helps!

Quite a few. Figure at least 7-8 uses, maybe more. I generally buy several at a time.

Every six months for two users. Well ....sensibles users. :-). If you frequently run out of hot water in long showers it will be six months for one user. :-)

We use ours at least 12 to15 times a year on a 2.5 A parcel, I'm on my 4th year and have a new one which I'll use next year. Hope
