I have developed menopause hair which is now so frizzy ! I like to get a keratin blow dry once a year to tame the frizz and of course with this you’re not supposed to use a sulphate shampoo which this is. So off I go on an expensive sulphate free shampoo hunt! I’ve spent so much money on top brands which all still somehow manage to irritate my scalp. It’s a constant battle. I wish PK could look to develop this itchy flaky shampoo as a sulphate free (I know they have a sulphate free option but it’s not the flaky itchy scalp one) … anyway I am back because there is simply nothing else that compares !
