I dont think i would buy again

I bought this shampoo and conditioner about 2 months ago in the 1 liter size. I still use it hoping I would see results and nothing yet. I find it makes my hair feel gritty if you don't leave it on for 3-5 minutes like it says. I don't see my hair feeling any thicker after 2 months of use, but ill still keep using it until its gone. I would like it if any one else tried and tested it and let me know how it was for them.
