This is by far my favourite shampoo to use as it doesn't leave my very thin hair looking flat. I find it leaves my hair looking shiny and really really smooth. A small amount of the product also goes a really long way so you're not consuming a bottle within a matter of weeks. I also noticed that the product after a few weeks of use improved the thickness of my hair (i.e. less breakage and hjair loss). The smell of the product is also really nice.
Would definitely recommend to people looking to prevent breakage. However, please be mindful to cycle on and off with this product and overuse of this product can actually have the opposite affect (due to your hair being saturated with proteins). SO one week use a non protein based shampoo and the other this. :)
