Do you feel that your hair is accustomed to the shampoo you use for some time? Of course, only fantasize. The hair on the head is dead cells and can not get used to anything. So does a hair treatment even works? Another issue is that you are familiar with the use of a shampoo and see the difference when changing the shampoo, but this is normal because shampoos have different active ingredients.

But the truth is that the shampoo you use for a very long time has the same effect and your hair can not get used to it.
