How to say that this product is ... MAGIC! I am constantly at war against my greasy hair. In full adolescence, sebum is really too excessive. I really galérais to space my shampoo less damaging to my hair. Between sport etc ... 3 days, it was impossible to hold. No dry shampoo had convinced me, leaving white residue .. After everything I've read, I left one last chance with this brand. This product is the original, I can not tell you anything about the other as I have not tried them, but this one is perfect! In 5 minutes, my roots are no longer fat, and my hair is no longer dull. They shine and take the volume. It's really impressive! So above all, please, I assure you. Especially that customer service is really serious. An old order had not arrived home, but returned at Amazon, and while I was refunded immediately. And deadlines are met. NOTHING TO SAY!
