My hair has been falling out a lot for 3 months now and I decided to try this since in the past I had also used the corresponding capsules and they had helped (back then the hair loss was due to significant weight loss, nothing to do with today when the cause is unknown). I have used it only a few times but it really has helped—when I wash my hair, the drain doesn't get clogged with hair, the situation is somewhat under control! I have truly seen improvement, but let me explain why 4 stars! I have long and oily hair, before I needed to wash it every 2 days when I was using shampoo for oily hair! Now with this one from Ducray, it just never feels clean, its composition is so oily that unfortunately my hair needs washing every day and even when freshly washed it doesn't feel clean or shiny, I feel it dirty, oily, and very heavy! And of course, the next day it definitely needs washing again! You might say this is medicinal, not a simple shampoo, we use it as a 'medicine'—yes, that's fine, but it should somehow also clean the hair from oiliness! That's all I had to say, there are also people who don't have oily hair and I believe it will be perfect for you! It helps with hair loss but it should be more cleansing for those of us with oily scalp!
