In general, it is very good.
Large packaging that withstands and lasts over time.
However, I did notice some differences compared to supermarket products, but not what I expected.
I would buy it again.

update 04/2023: Nothing has changed compared to what I wrote earlier, I don't know if I would buy it again because almost 6 months have passed and I haven't seen any improvement. However, I would prefer it if I had to choose between supermarket shampoos and this one.

Very good shampoo. I also have the corresponding mask from the same series. I believe it helped my hair a lot after bleaching.

After using it for 2 months, I can say that it is not like the common shampoos from the supermarket. It softens the hair and has a pleasant scent, but other than that, I didn't see a significant difference

Very good product, no comparison with common shampoos on the market. While I used to need to wash my hair every 2 days, with this one it doesn't get greasy easily and I now wash it every 3 days. The large packaging is worth it. In combination with the hair mask, it has very good results.

It takes a lot of quantity to create foam and make your fingers glide when massaging. Also, it takes a lot of quantity each time to fully clean the hair from styling products.
