A simply mediocre (at best) product. The application is relatively easy because as soon as you put it on your hair, it dries and makes it "stiff". So if you haven't combed your hair before and you expect to apply it afterwards, you won't have success. Also, I should mention that on freshly washed hair (when you have just come out of the shower and your hair has dried), the application is very easy. But in the opposite case, even if you comb your hair, it is applied quite difficultly.
The hold is good on a calm day (without wind, without touching your hair or anything else), meaning it keeps your hair in place. However, if you go out and there is wind, well then you will have a big problem. It doesn't keep it in place and unless you want to stop every 2 minutes to fix it (carrying a comb and mirror with you), then it's not for you.
The result is indeed matte and the scent is quite good, but otherwise I wouldn't characterize it as a good product. Keep in mind, of course, that my hair is fine and relatively short, and it is not straight. (Perhaps it applies more easily to people with straight hair)

Mediocre product. Although the application is very easy (I must mention that it is not even clay, even though it claims to be. It's more like a paste that resembles clay), the hold is nonexistent!
Let me start by saying that it dries very easily on the hair, meaning that as soon as you apply it, the hair has already "hardened". It doesn't stick at all (which I find positive compared to another similar clay I had) and gives a relatively matte finish. When I say relatively, it's like being licked by a cow (literally) and then drying afterwards.
As for the hold I mentioned earlier, let's just say it's strong. For example, I went out in the wind and my hair was all over the place. It's better than not using anything, but I don't consider it a worthy product. And as for the longevity, it's a joke! I applied it in the morning and by noon it felt like it had been left over from the previous night!
The only positive aspects are that it has a nice scent (smells like soap) and it spreads easily on the hair without sticking. Now, if someone just wants to apply it for 1-2 hours during a casual outing (without wind, without disturbing the hair at all), then yes, it's worth it. But for everything else, it's so-so
