Joico vs. Tigi - which is best?

joico definitely! i have been using this for months. the kpak. the keratin is a lot for my hair because i have an oily scalp but if your hair is dry, this is perfect! using both is obviously the most effective. i have definitely seen a difference in my hair. it works so well that i can't use it all the time because now my hair is a bit greasy looking from allll of that protein. just use it when you really need it and it works wonders:) hope this helped
