Advance Techniques leave in treatment/strengthen and protect

Advance Techniques strengthen & protect is a leave in treatment for all hair types with Arginine and Keratin proteins.
I bought this product a while ago and it made me sad. It is a 100ml container.
My hair is dyed but it's naturally thin so I need a good product that helps to prevent breakage.
Unfortunately this product didn't work for me at all.
My hair quality stayed the same, it didn't change in any way so I use it time to time just to finish up the bottle :)
Nothing so special about this product although I like Avon products very much.
