It resembles the corresponding one from Redken. It is a 5-minute treatment before washing, no more is needed. A mask or conditioner is required afterwards because it is not intended to make the hair soft.

I didn't go crazy..I don't feel my hair is hydrated..I got the whole line...and the leave-in serum...a bit sticky and it doesn't provide any hydration at all..

Very good result. I didn't find much difference from Olaplex 3, which is more expensive. I don't have damaged hair from dyes, but I have dry blonde hair dyed with regular dye. (not bleach). I will buy it again and I won't pay for expensive products for the same job.

I only bought the shampoo from this series and it is very good. I believed it was the best of this company and it really is very good. Bravo to them for creating something that resembles the expensive shampoos I have tried over time. I imagine if I also get the other two products from the series, I will be even more impressed.

I have purchased all four products. After the third use combined, I really saw a difference in my hair, which I had never seen with supermarket products. My hair became soft, frizz improved, and with a simple blow dryer, it smoothed out perfectly, which I did not expect. Even those around me noticed the difference. They require a good rinse because otherwise the hair feels a bit heavy, but other than that, I am very satisfied. They truly deserve it and have nothing to envy from very expensive product lines that personally did absolutely nothing.

I have bought the pre-shampoo, the shampoo, and the conditioner. Okay, I don't want to sound exaggerated but guys, personally, I was thrilled! First of all, let me talk about its scent, which is the best! And it stays on the hair for hours. I recommend getting the whole range to see full results. My hair has been dyed many times lately because I changed the color. They are damaged and dry. With just one application, I saw results and for me, that is impressive. It made them incredibly soft, the shampoo does not have SLS, it is gentle but foams up. It literally transformed them. It's as if I had an expensive treatment at the salon. It made them shiny, glossy, gave them volume, truly restored them. I highly recommend the entire range. It is professional-grade, no comparison to supermarket products. And the best part is that they are available at the supermarket and their price is relatively affordable. The best thing I have ever bought and I don't think I will stop purchasing them! They are worth it! I didn't expect it, and that's why the joy is twofold for me! My opinion: they all work together cooperatively (like all the products), not individually. Get all four of them to see full results! They compete with extremely expensive salon products.

I have oily, thin hair and my daughter recommended me to buy a leave-in serum. By far, the best leave-in I have tried. It leaves the hair incredibly soft and shiny without any trace of greasiness! It also tamed my curly hair and gave me nice curls! I won't change it! I highly recommend it.
