bought two bottles based on recommendations and clinical check. finished both bottles in couple months or so, initially regularly, then after every wash. didn't notice ANY improvements about grey hair or quality of hair overall. Spray form is not economical at all, hard to apply right on scalp. Though the review stated that it's more like a fluid, it's liquid and application requires to put more than "two drops on all the head". after a while started feeling bit greasy on hair. Don't have any intentions to continue or second buy unfortunately

Прекрасно!

Melted this vegan self-tanning mousse for a natural bronze. No smell. Clear on application. Doesn’t stain. Fades evenly.

Interesting

Easy to use on the hair, nice scent, no irritation to the scalp, but obviously it takes time to see the real benefit. Seems to be of good quality

Not enough quantity’s

The amount is so small you use so much in one application it doesn’t make sense. If you want to cover your whole scalp. Has anyone else found this to be a problem?

Nice but no result yet

Haven’t seen much results yet, but I like that tingly sensation. The bottle is too small though and you need to apply a lot to cover the scalp

The product is excellent, the ingredients are lovely, the quantity is suitable, it has good immunity, the hair is wonderful, but the packaging is unhealthy, I think.
