I heard about this product on YouTube by a popular grooming Channel. Than I decided to buy it. You have to use twice a week. This is a Mild Shampoo, If you have a dry scalp than you can go through this. But this is harsh reality that this decreases your hair density and treats your hair smoothly. I would suggest you that first you have to check the condition of your scalp and than buy this. Definitely this affect your hair density but gives strength to your hairs and make them shiny so you can easily use it. This is a sulphate and parabeens free shampoo. And I have a good experience with this. I also suggest you to use the WOW conditioner with this shampoo once a week. And you also know that this is most recommended shampoo on Amazon. So I would say that yes this is GAME CHANGER.
