Products for fine hair

Finally some salon hair care products became available in the pharmacy stores, at least here in Canada I can buy lots of designer products in Pharma Plus or Shoppers Drugmart, so there is no need to call through the salons, ask what line do they carry and then drive to another part of the city just to pay enormous amount for little bottle of shampoo.
In general I noticed that no matter how good the product is after long time of using it - it just stops working, so you need to change it for a while.
These are the products that I tried:
Joico K_PAK daily shampoo and detangling solution - hair looked shiny and healthy, there was no volume increase but detangling conditioner helped a lot - I had longer hair at that point and, before using joico detangler, combing them would just leave half of hair on the comb tangled into balls.
Thicker Fuller Hair - this is a great line to try if you are thight on budget. This product definitely gives a volume, I even thought that my hair felt coarser - you know that feeling of baby fine hair that you get used to - it was gone.
Biolage Bodifying shampoo and conditioner. It was excellent until at some point my hair didn't look clean and shiny after washing anymore.
Sebastian - bought it, tried once, not my thing. I found it gave a lot of moisture to my hair.
Amplify Volumizing shampoo followed by Amplify volumizing conditioner. It works wonders especially if I don't blow dry, just let my hair air dry and go easy on conditioner - while using one bottle of conditioner I go through two bottles of shampoo - applying it only to the ends and rinsing right away. After one and a half year it still worked. Give it a try if you didn't yet - definitely worth the money spent.
I would still use Amplify, but then read encouraging reviews on Redken line for fine hair, as a result now I am using Redken Body Full shampoo and conditioner. It is pretty good product too, just feels a bit squeeky - as in too clean and light and tangly on my hair. But the good side is - I was able to move from everyday washing to almost every second day. Hair look very healthy and shiny. I would recommend this product for shorter haircuts that don't suffer from tangling much.
I don't plan to keep using Redken after bottle ends. Next I am going to try Rene Furterer and Phyto brands (I just read reviews but never tried them) and if they are not for me - will get back to Amplify.
