Hello - I am looking for alternatives to brazilian keratin treatment / blow-dry that I can use safely while pregnant. Not really looking and feeling my best right now so at least I can try and get my hair looking half decent - blow drying it at the moment takes ages and I'm still left with loads of frizz and unruly curls. I've heard of Frizz Ease 3 day straight and Tresemme keratin 7 day smooth which you can buy from boots. Are any of these any good?
