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

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

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.

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.
