very good. with a very small amount it makes a lot of foam. generally it makes the hair soft and nice when drying.

Great shampoo, but my hair easily gets used to shampoos and then I have to change them. I used it for about eight months and it was perfect

I am using it for the first time and I bought it as a supplement together with the reconstruction lotion...I am satisfied

This is a very dense and thick shampoo. Try to use half of the quantity you usually apply with other shampoos and it will do the job perfectly. It is very gentle with the hair and leaves a nice feeling after washing.

I have been using it for 5 months now and it has helped me a lot with hair damaged from dye and highlights. I use the entire Olaplex range and all the products are amazing.

3.5 ⭐ (but I give it 3 because I don't think it deserves more than 4)
I bought the 250mL through Skroutz hub (I mention this because I have seen fake Olaplex products circulating) trusting Skroutz to have authentic products. The shampoo doesn't have any particular scent. It is very important to use a small amount, you don't need more than a hazelnut-sized portion, especially for the second wash, no matter how long your hair is. Let's not forget that shampoo is mainly to clean the dirt from our scalp, not the ends. Now, the reason I give it 3.5 is that it promises hydration and doesn't deliver. It doesn't dehydrate the hair, but it doesn't hydrate it either. In any case, it's a much better choice than supermarket shampoos and thanks to the minimal amount needed, even 250mL might last as long as 3-4 equivalent bottles of typical shampoo. Overall, good but not ideal and definitely not what it claims to be.

Very good, it really made a difference to my hair which was dry and damaged from highlights and nothing like the mud that I saw it being compared to in other reviews! You just need a small amount (even though I have long hair) and after you apply it to your hair, add some water with the shower... I also got the mask from the same line which is also amazing. They are not particularly expensive, especially if you buy the liter bottles which last a long time. I will definitely buy them again

I have blonde hair from highlights.
I feel like I'm washing my hair with mud every time... it has a muddy texture... my hair gets oily even faster and feels weighed down.

Good, cleans well, only a small amount is needed. Much better than the supermarket ones, quality-wise of course. You definitely need conditioner at the end, preferably from the same brand. When you straighten your hair, it lasts and makes it stronger.

I expected much more from this shampoo. I have fine blonde hair with balayage, it makes my hair quite oily without moisturizing it! The only good thing is that it requires a small amount.

It is indeed expensive for the quantity, but it is like concentrated, meaning you will need much less compared to one from the supermarket, and I say this as someone with very long hair. One bottle lasts me 3-4 months, using it with every wash. Also, I take great care of my hair and it has always been in good condition with the fine hair I have, nevertheless, since I started using it, my hair grows very quickly. For good and economical results, I do the first wash with a regular shampoo to remove impurities and "dirt," and the second wash with Olaplex. I will continue to buy it forever, really. I recommend it with my eyes closed.

The best shampoo ever!
I have blonde hair but not damaged thanks to Olaplex! I have the whole line for years... everyone tells me how wonderful my hair is! And all of this thanks to Olaplex. I have tried many well-known hair care products in the past

Expensive but worth it. You wash your hair fewer times a week, so you use less product. I also saw a huge difference in my hair, which because I mistreat it a lot needed to be cut for split ends three times a year. I used these shampoos and conditioners and only needed to cut it once. For me, they worked great

It is very good! It does what it promises!
This time I bought another well-known brand, as my hair is very damaged and I wanted to try something more "advertised". However, I believe that I will buy Olaplex again!

Honestly, the worst thing I have ever tried! Hair like mud, greasy and unimaginable dryness, which I have never had before!

It is suitable for all hair types and with a small amount, you can wash a lot of hair. The price is the only negative aspect.

The first sulfate-free shampoo that I try after reading about their benefits for a long time. I didn't expect it to make much of a difference, but after the first week of use, I saw results both in my hair and even more so on my scalp.

Only the scent is worth it. Otherwise, I wasted my money. Not to mention the quantity. Pure deception.

The shampoo is garbage, it caused hair loss even though I didn't immediately realize it was from the shampoo. I didn't have any other issues like stress or poor diet, and it also leaves the hair very wild

The packaging is very small for its price, especially if you have long hair like me, it finishes quickly, although the shampoo in the series foams a lot! Overall, overrated, personally I didn't see any difference in my hair.

If you choose not to buy a product again as soon as it finishes, it means something. I don't know if it does what it promises... at least on my hair. Maybe it's overpriced.

Disappointing product, I had to throw it away after 2 weeks of use. It leaves the hair very dry, to such an extent that it damaged the ends (and we're talking about a healthy, freshly cut hair). Only Kerastase, in my opinion, for professional care.

I had an allergic reaction. I was itching a lot and developed redness on my throat. It took me a month to figure out which product was causing it. As soon as I stopped using it, the symptoms disappeared. I don't understand why it is heavily advertised despite causing allergies. It was mediocre as a supermarket-type product.
