What Kind Of Hair Treatment Is This?

my hairdresser talked me in to a treatment that is temporary that she said will hold the frizz and curl down for 2 wks. she washed my hair then massaged this stuff in. it sat 5 min, then she put a cap on the hair and put me under the dryer for 10 min, then washed off. it leaves your hair soft and sort of frizz free. does anyone know what this is. ?? we happened to be talking about keratin treatments when she suggested this. but this is only a tempory one.
