مصل منشط للشعر الشبابي Kerastase Densifique Serum Jeunesse

I didn't buy it here, but I will leave a positive review. This product is very effective and lightweight, making your hair simply incredible! Hair loss has stopped, and there is shine and radiance! My dyed, dry, and thick brittle hair has become healthier and more shiny!

I really wanted this serum, and it is quite expensive. So, while I was in Poland, I bought it from you.
I was very disappointed because my hair became thinner and started to fall out more after using it. The serum doesn't provide any volume and doesn't have any effect on hair loss; it actually dries out my hair even more, especially the ends. It's really bad!
The only good thing about it is the smell, which is very nice.
I have a question: I'm really regretting spending money on it because I tried it only twice. Can I return the product to you even if I threw away the receipt?
