Depends on what you mean by rewetting. If you mean soaking hair like when you shampoo, then yeah, you can tame frizz without going that far.
You can use a spritz bottle to moisten, but not soak hair (so it would dry in minutes) and add a bit of product (I like to use CCCC
Lite or CIAB
or a moisturizer with some light oil to it).
Or if you want, you can apply some products to dry hair to quieten frizz (though I never see it totally eliminated). I find CCCC
Lite by Curl Junkie works really, really well for this. I've also used CIAB
and SS CEJ and Flax Seed Gelee on non-wash days to freshen curl and calm frizz. Some ladies swear by using a small amount of Jane Carter's Nourish and Shine (it's a pomade) to smooth down frizz and up shine on second day plus hair. Other pomades may help, too.
I think the best way to lessen frizz is to use products that work well for your hair type, keep it well moisturized with deep treatments weekly or every time you wash, and then protect hair from too much friction/movement/displacement by taking care how one sleeps on it.
But I don't know any cure for all frizz other than to oil up hair so much it looks greasy (and yes, I've gone th at far and it's not purdy). That took care of the frizz and gave me shine, but I had flat, low volume, heavy hair.
Needless to say, frizz will occur if you touch your hair a lot, comb or brush it while dry, roll around having energetic whoopie without a pineapple, hahaha
