Review (1/5): It hasn't worked for me
I've used this shampoo 5 times and my hair hasn't changed a bit. Also, it leaves my hair feeling rough. I have to put a conditioner in after using and according to your sales pitch, this shampoo is supposed to darken the grey, make the hair thicker and longer. I don't know how many times I need to use it to see it work but so far I am very disappointed.
