First of all, don't expect to grow hair from all these shampoos, ampoules, etc.; the only thing they can do, if they are indeed a good product, is to delay or even stop (in very few cases) hair loss.... THAT'S IT. Don't expect miracles!!! If you have a serious problem, you should see a doctor, and even then, it doesn't mean 100% that it will be fixed, especially if there is heredity involved. After several uses of this particular shampoo, I can say that at least for me (because the scalp varies from person to person), there is a toning effect on my hair, and since I have oily hair, I believe it corrects the oiliness, contrary to other comments I read. Keep in mind that the shampoo, as stated in the instructions, should be left on your hair for at least 5 minutes, twice, to be able to work, and usually, all shampoos of this type need time to take effect; they are not like regular shampoos that you wash, rinse, and go. It requires some patience to give (if it can give) results!!!!

I have been using it for a week now. It dries out the hair a lot and makes it difficult to comb. I don't have an opinion on the result yet
