Now I understand this craze came along last year and I am very late to the game. So apologies if you have read about this else where and I am 'so last year' and all that.
I actually only came across this
I was reading one of my favourite beauty bloggers who I am obsessed with. So much so that when a new post came up on her daily hair and make up routine my prayers were answered. She casually dropped into it that she reversed washed her hair as though this was common knowledge. Thanks to the help of Google my ignorance was cured and my curiosity fuelled.
It is pretty self explanatory - you first put the conditioner in and leave for 3 minutes. You then splash a bit of water on the hair, but don't wash out the conditioner. Then lather in some shampoo, wash it out, blow dry and ta da! You are then left with fresh shiny hair as though you just stepped out the hairdressers.
