Review title is I Don't Get It [SEP] A couple of years ago my hair was in rough shape from bleaching and coloring. I found out about Olaplex shampoo. After a couple of weeks of using the shampoo my hair was in such improved condition I was seriously impressed. So I invested in the No. 5 conditioner. It was okay, but really no more effective than any decent conditioner. After a few months, I had had a hair cut, continued using Olaplex No. 4 shampoo, and my hair was in pretty healthy shape. But, I figured I could make it even healthier by using the No. 0 and No. 3 method. The first time I did it I didn't notice anything, at all. So I thought I'd try it again. Nothing. A few weeks later (considering the availability of the trial sizes) I gave 0 and 3 another try. That time my hair was dry, rough, and flyaway. Anything but sleek and well-bonded. As for the No. 8 mask, again, nothing outstanding. The take-away: I love Olaplex shampoo, both the regular and their purple for blondes shampoo. As for the rest of the Olaplex line of products, I am not at all impressed. They are so pricey, but tend to either do nothing or damage rather than repair. Aside from the shampoo, I'm calling Olaplex way overrated.
