Instead of spraying hairspray or laundry products in your hair don't brush it that will make it more staticy, just wet your hands slightly and run them through your hair. You don't have to have soaking wet hands just slightly damp. I hope this helps you not have to put laundry projects or hairspray in your hair.
I always used hairspray, spraying it in a hair brush or on a comb and running it through my hair - no sticky helmet hair and it settled it down nicely for the day - and it is a product made for hair, unlike fabric softener.
Then I discovered John Frieda's FrizzEase at the local K-mart. I like the serum - just a drop or two worked into my hair and my hair behaves for a couple of weeks, but there are several other types of products in this line you could try as well.
Most importantly, increase the humidity in the air with a humidifier. It should be at least 35% for comfortable livable conditions; I keep my house between 40 and 42% during the dry winter months - it does not take much cold dry air to suck that moisture out of the air.
Believe me...I have super long...super thick and super curly hair...plus I live in the south where it is very humid - hot as the dickens in the summer and cold as a well digger's butt in the winter - so static is a problem and so is frizz - obviously - and nothing works better than dryer sheets for static (like some others have mentioned) and for taming frizz...plus it makes your hair smell nice. Also, if you have used a straightening iron on your hair - which I wouldn't recommend too frequently because it does damage your hair...they help as a touch up to smooth out the ends - you take two dryer sheets and pull sections of your hair between them - they smooth the hair back out and make the "smooth, straight & shiny" hair last longer.
