Matrix Biolage Smoothproof Shampoo And Conditioner Duo Pack 2 x 1l

I decided to purchase the 1L bottle packs of shampoo n conditioner after my hairdresser used samples on my hair.' I have thick wavy/curly hair and can often appear dry and frizzy unless its got product in it. I noticed after using the matrix for awhile how much more manageable my hair was, it felt amazing, and the smell of your hair, even several hours later is sensational! My hairdresser even commented several times how healthy my hair was! The 1L bottles lasted me approx 4 months (cant remember exactly when i got them and also i busted my 14 and 11 year old using them from time to time :) ) even so at $27 a bottle each, it works out approx $1.70 a week for your decent salon quality shampoo and conditioner. I wont ever use anything again!! I will tell you but, that each time I order new bottles I order a different type. For example, the 1st one i ordered was Smooth Proof, the 2nd was Hydra Source. I was told that your hair can get used to it and not seem to be working as well as it did at the start after prolonged use. I am not sure how true it is, but it works for me. My hair has never felt better!
