It produces a pleasant amount of lather for its size and smells fantastic.
I have very oily hair and after washing, it literally squeaks with cleanliness.
I don't think I will go back to store-bought shampoos after this one.
Update: Almost a month after using it, I noticed fewer hairs in the bathtub drain than almost always after washing.
Now, I wouldn't change it for anything.

After using the product for just over a week I can say it has dramatically improved my hair ! and less breakage and falling out

It smells nice! If you're in a hurry, it's not... It's quite a difficult process. It leaves a feeling of cleanliness! I will buy it again!
My husband, who has oily hair and needs to wash it daily, tried it. And with this, his hair can last 2-3 days without getting greasy!
I had an incredible itchiness lately with conventional shampoos like Pantene (without symptoms like dandruff or dry skin). I was saved!

I hadn't washed my hair for a while - which is extremely damaged - and to feel that they are already soft before applying a mask. Amazing hydration. I recommend it!
