Very good shampoo from a Greek company with a nice scent. It is one of the mildest shampoos, without sulfates, so it foams less than regular ones. Its use should be according to the hair type - for example, in my case, with fine oily hair, I alternate between this shampoo and a regular one (with sulfates) for better cleansing and less oiliness.

I am very picky when it comes to shampoos since I have a sensitive scalp that occasionally shows dandruff and hair loss. We used it with two people and we agree on the following:
It significantly reduces oiliness but not to an extreme extent. However, it leaves the hair soft and shiny. It has a wonderful scent. You don't need conditioner. We also both noticed a difference in hair loss, which may be coincidental but it's worth mentioning.
The negatives are that it doesn't lather (which I expected), you use a lot of product on long hair, and I have the impression that it weighs down the hair and is not easy to rinse out.
