I have very thick, dry, slightly wavy hair which is a nightmare to style. It’s ok when just straightened but when I go outside it goes poofy/ rizzy. Would love it to be sleeker/shinier/more manageable! I’ve been looking at either Olaplex 3 or 6, though noticed there are some knock offs eg Revolution, and for the same price I could get the whole range rather than just one product. Any ideas on which might be better (ie one of Olaplex or using whole range of another)?! Or any other brand recommendations? Thanks!
