5 stars because it is the only one that creates a rich lather as you add water compared to the others that are for keratin. Unfortunately, hair gets oily faster so more frequent washes are needed. Nice scent as well.

Very good shampoo. Ideal if you have keratin. It also makes a lot of foam, which keratin shampoos usually don't. The only relatively negative thing is that it doesn't have any amazing scent

For me, it is the best shampoo for those who have undergone keratin treatment... I used it and it lasted me a year and I believe that the shampoo played a big role. While other ones I tried didn't lather well, they left my hair feeling heavy... this one was wonderful! A bit expensive but very good.

Shampoo recommended for keratin maintenance. It does its job, but the gold shimmer it gives is only for effect in my opinion, it sticks to the bottom. Initially, it seemed like the color of the bottle. It does not mix even with shaking the bottle. Now that the shampoo is finishing, I scraped it with a wooden object but it was stuck to the bottom for good. I think the effect is unnecessary. Something more general and important, in my opinion, that I would like to point out is the absence of a complete list of ingredients in cosmetics and personal care products on Greek websites. I believe it takes away the consumer's right to check what they are buying. It is good for this to change and for someone not to be obliged to refer to foreign websites that have ingredient lists. The ingredient list is the only way to protect the consumer.

Very good product, especially for those who do keratin. I don't know why I hear that it makes the hair oily or dry. Just for your information, shampoo alone doesn't work miracles. Hair needs occasional special oil, conditioner, and mask, while always washing it twice, two hands. Also, every person has a different hair type, some more dry, some more oily, and sometimes someone may recommend the wrong product.

The next day after using it, my hair is greasy to the point that it feels like I haven't washed it for 5 days!!!! They recommended it to me at the hair salon, if you can believe it!!! I do not recommend it at all!!!!

The worst thing ever!! My hair generally doesn't get oily, but when I started washing it with this specific shampoo, the next day instead of looking freshly washed like with all the previous shampoos, the result was exactly the opposite, by the third day I desperately needed to wash it!! I spent a bunch of money and ruined my hair!
