Bests & Worsts Reviews from Amazon

These are not authentic. I do feel like it made my hair feel nice, but that is the only reason I’m giving two stars. I bought some more Olaplex no. 0 and no. 3 from Sephora when the bottles I ordered from Amazon were getting low. When I used the new Sephora bottles the no. 3 was visibly thinner and had a more yellow hue than the Amazon no. 3 bottle. The olaplex from Amazon was white and very thick, so thick it just stayed in the bottom of the bottle when I flipped it upside down, while the Sephora bottle was thin enough to move quickly as you turn the bottle from side to side. The labels also seemed slightly different. I will definitely be ordering from more reputable stores from now on.
