I have fine hair and oily roots. I definitely needed to wash my hair 3 times a week. I used it exclusively for 2 weeks and then once a week along with another shampoo for oily hair.
It is not a mask, but a shampoo. It lathers a lot. If my hair is quite greasy, I first use the other shampoo to remove most of the oil and then I dip my fingers a little in this one so I don't take a large amount and apply it to the roots. I rub them well and with whatever foam I have, I also go over the rest. I rinse well and apply conditioner.
As for hydration and strengthening, I can't say I've noticed anything special after a month and a half of use, but it does work for oiliness. Its smell is as described, like eucalyptus, but not unpleasant. Anyway, it doesn't linger in the hair. You don't need a large amount, so it lasts a long time. My hair is dyed copper and it doesn't ruin the color even though it's sensitive. I will buy it again.

Very good mask. BUT, it needs a strong moisturizer immediately after, because it leaves the hair feeling like straw when rinsed. It works very well with oiliness, it does what it promises - volume, lightweight hair, deep cleansing against oiliness. I'm bothered by the eucalyptus-tea tree scent, but okay, almost all shampoos/masks I've tried against oiliness smell like that.... They call it freshness.... I will buy it again.

It is shampoo, not a mask. I used it for 2 out of the 3 washes/week that I did for the first 2 weeks of use and then, after the oiliness in the roots had significantly decreased, I now use it for 1 of my weekly washes. And now I don't need 3 washes every week anymore!

I had a sample from a well-known cosmetics store, and as soon as I tried it, I bought the full-size packaging. It leaves a feeling of cleanliness and freshness, and the hair is soft and lightweight after use

There isn't! It's not actually a mask. It's like a mask that foams as soon as you put it on your hair. Like a shampoo. It removes any trace of oiliness, leaving the hair really clean and voluminous. For me, who has extremely oily hair, if it was possible, I would use it as my permanent shampoo. AMAZING

I have been wanting to try this specific product for a while now. It is not a mask in the traditional sense. It is like a shampoo that is used once a week for cleansing and hydration at the same time. I have to say, it is fantastic! It cleanses very well, respects the color in dyed hair (very important for me), and leaves a light and voluminous feeling! It also smells wonderful!

I had a sample of it and it is excellent. I did feel a slight burning sensation on my hair and immediately afterwards they felt very clean and light. It is a cleansing mask and it helped a lot with the greasiness
