Second application of keratin fair swishy treatment today, first lasted three months and has been fabulous. I have used salt free shampoo and conditioner but reading packaging it only says about salt Fred shampoo. I have three if those huge tubs of Treseme conditioner ( been using their keratin ones) for the first time ever I have washed my hair after three days, has looked and felt fab and with a newborn and two other dc had been a godsend!!
