First time a product actually works from the first application, on my damaged hair. Worth it!

Amazing product! From the very first use I saw a big difference in the ends of my hair... which had become very weak after bleaching and dyeing! I will definitely use it 2-3 times a week!

This particular product really works wonders. You need to follow the instructions closely for maximum results. From the very first use, the difference is noticeable, the hair feels fuller and smoother. With the next 2-3 uses, the hair gets better and better!! The best way is to wash your hair just with shampoo, without conditioner or mask, gently towel dry your hair and apply the product from the roots to the lengths, with extra emphasis on the ends where there is more damage. 30-40 minutes is enough, then wash your hair as usual and then use a mask for about 10 minutes to lock in the moisture.

It does what it says, I have hair after a perm and I didn't believe it would give such hydration! My hair is shiny as if I just came out of a hair salon! Worth every last euro

What can I say about this product! Even in ten minutes, it softened and gave body to my hair, which was dry from bleaching. For me, the only things I need are this and a shampoo without sulfates.

It revived weak and damaged hair from split ends and dryness. However, it does not make it grow longer. Decent, although expensive. If I had more hair, it would run out much faster. Also, the remnants are very difficult to remove, meaning residue remains that needs a lot of effort to come off. Although it helped, and although it was money worth, I would not buy it again because my hair is not damaged by dyes

It's good but I wouldn't buy it again. I have now found cheaper products that satisfy me more

Whatever I say is not enough, it's the best thing I've ever used on my hair. I buy it and I don't even know for which time. Unfortunately, it doesn't last long (runs out quickly) and of course it's very expensive. Buuuut my hair loves it ??

I did the treatment with No0 and No3 on hair damaged by bleaching, which break and tend to tangle and form small knots. When I rinsed the treatment, I was momentarily thrilled because the hair felt like in between, however, after washing it with regular shampoo, that sensation disappeared. I might need to buy the shampoo from the line to maintain the result. I also used No8 as a mask, but my hair was perhaps more wet than it should have been, and it seemed like the mask "disappeared." On slightly dry hair, No6 and No7 worked. On completely dry hair, it was the first time in a while that I could use a fine comb. The next day I could still feel the leave-in No6 and 7, but unfortunately, small "knots" had formed again. This was without re-combing my hair for 24 hours. Damaged hair is only a small part of my hair; the hair that hasn't suffered from bleaching feels like silk with just No8, 6, and 7. I will return when I do the treatment with No0 and 3 again.

I find the packaging problematic, you have to almost break it by squeezing it for the product to come out... It did nothing for my hair, it has no scent and its texture is unremarkable. Very expensive for nothing. What can I say, maybe you need to use all the products in the line... Personally, I wouldn't buy it again.

very heavy product softens the hair but weighs it down a lot I stopped using it and now I use the redken acid bonding line which is much better

It upgrades the quality of the hair. A wonderful product, which however needs to be used according to its instructions in order to work, otherwise it's a futile effort. It is a treatment, not a mask or conditioner (the company has such products, just with different numbering, e.g., the conditioner is no.5). Therefore, if you are going to purchase it and invest in the product, make sure you know how to use it. On the downside, it requires a considerable amount of product during use and the 100ml packaging will not last long if you have long hair. Either way, I buy it again and again because with its use I saw a significant difference.

treatment that you leave on all night,,, after washing it moisturizes excellently,, combines with its own shampoo and conditioner and then the cream for frizz,,, like a complete treatment

Unfortunately, the specific product I received has nothing to do with the one shown.. Inside it is pure white while the smell resembles that of a lotion. The actual product does not smell like this and its color is yellowish. Its sticker is silver instead of gold and when I used it, my hair was dull and dry. With the regular product, my hair was light and silky from the very first application. It's a shame because it's very expensive. (Calvani)

I used Olaplex 3 and the number 8 mask for a month. From the first time, I noticed various changes in my hair as it was easier to comb and softer, but by the third time, as I was using them once a week during washing, I experienced hair loss, and the same happened in the fourth week. I simply didn't use them again; I threw away what was left and hope the hair loss stops there since I have never had a problem with hair loss

Mediocre for its price, nothing amazing. I have gotten much cheaper masks that hydrate more. I don't think I will buy it again as you expect much more from a product with such an expensive price.

It really does what it promises; from the first time, you see noticeable differences.

I bought it with number 0, but I didn't see a difference with that. I think this one is better on its own

I have curly hair and I usually leave it for half an hour before the shower after wetting it, once a week. It gives me the most beautiful curls and with regular use, you see a difference in the hair.

It is not a mask. Many people think it is a mask and use it after shampooing. If the hair has styling products on it, it would be good to lightly wash it before. We leave it on for at least 10 minutes and then wash and apply conditioner, mask, or whatever else we want. Of course, a hair oil is also necessary if we have frizzy hair. In my case (hair damaged from dyeing), I saw immediate results from the first use. It gave me back the softness, shine, and cleanliness of my childhood hair. Proper use brings the right result. It's worth every euro. You should try it!

The multiplex is a category on its own. This product has saved my hair from many damages and blow-drying.

The best product... I had the treatment at the hair salon... and I continue at home... with the 3...4...5 and the silver.

Amazing!!! I never saw my hair like this before. It's truly like having a hair salon at home. I tried many treatments and didn't see any results. With this one, from the first application my hair seemed to have double the volume and shine. A bit expensive but cheaper than an expensive treatment at the salon

With the very first application, I saw a difference in my hair. It became more hydrated, more elastic, soft like cotton, which had been damaged and was dry and brittle due to styling. Of course, we don't expect miracles and for the hair to suddenly become something else, but what it promises, it clearly delivers and it does so in the comfort of your own home!

The only thing that works from Olaplex is the 4 in 1!!! I have given it many chances but I didn't see any difference

I bought it in the summer because my hair felt dry and brittle. It does something, but I can't say that it moisturizes. You also need a good oil afterwards to see an improvement in texture. It definitely makes them more manageable though. You'll see that straightening/combing becomes easier afterwards.

I can't confidently say if it's worth the money... honestly, everyone sets their own standards. But I would say that it can be used several times... it makes you save a bit on the product and still see results.

I have hair that has been balayaged... relatively good quality hair, not damaged.

The only product out of all the ones I have generally bought (shampoos, masks, oils, etc.) that actually does the job and helps the damaged hair.

I bought it after a lot of research because I heard great things about this product.
I have thin hair, normal hair density, and colored hair. I have curly hair and I use a flat iron (heat) twice a week for straightening, so I would say there is moderate damage to my hair. I don't have damage from bleaching, for example, but I do have split ends and damaged tips...
I have used it three times so far. Unfortunately, I can't say that I have seen any results... I leave it on for 1-1.5 hours on damp hair, rinse, shampoo, conditioner (or mask), and that's it. I will reserve judgment for the future... I will revise my review if I see any results.

I don't know yet if it does what it promises, it definitely moisturizes and leaves the hair shiny, but I can't say that I saw a difference in hair reconstruction. I have thin and dry hair, of course I didn't leave it on for more than a quarter, I will try it for a longer time, I have used it 3 times and the bottle is halfway.. I have hair up to my chest

I used it twice and both times it made my hair look like straw, even though I kept it on for a maximum of one hour. It was disappointing, luckily it was a gift and I didn't pay for it
