The ingredients should be declared in my opinion clearly and openly - then everyone can make smart and decide whether he / she wants to do on such a hair.
That the hair feel great first is another matter - but I had from my hairdresser and a skin care product with silicones a few years ago there - and the quality of my
Hair has been gradually getting worse!
As I said, everyone can decide for themselves the yes - but then you have to have at least clear info's decision-making.
