Years ago, a stylist recommended an Olaplex product for my highlighted hair. It made my hair really dry and didn't seem to do much for my overall hair health. I was perplexed and disappointed because Olaplex was the all the rage.Fast forward to last week when I decided my hair was a mess and needed damage repair. I'm middle aged and my hair is very long and slightly wavy. I highlight once or twice a year. Decided to take a chance on this set after doing some research on the best products for my hair type.I first used the pre shampoo bonder followed by this set. Afterwards I applied the No 6 smoothing leaving in bonder. It took a couple of days for me to realize how great my hair looks and feels. It's very shiny, soft and manageable.I usually style my hair by air drying and then using a round dryer brush on it. Sometimes I hot roll or use my Beachwaver. After using this regimen, I did nothing but towel dry and my hair looks terrific.The shampoo has a rich creaminess to it and a little goes a long way. The conditioner is thick as well, but spreads easily form scalp to ends.I was concerned that such small bottles of product would disappear quickly, especially given my hair length. Washing twice a week I feel confident that this set should last me a full month. Small price to pay for such great hair.Happily surprised and looking forward to trying more Olaplex products.March 2026: I wanted to update my review. I can't believe how much better my hair health is since I've been using this group of products. I never do anything but use these products and towel dry and my hair looks terrific. I have a natural wave to my hair that is suddenly far more pronounced. My waves have turned into lovely little spirals, and my hair is the shiniest it's been since I was a child! My hair is also softer, and the texture is far less fragile. I'm 55 and my hair look better now than it did in my 20's!! I'm sticking with this routine. When your teenage son tells you how good your hair looks you know you're doing something right, lol.
