"There is no shampoo without sulfates. These are business tricks."
This is a sentence people say when they confuse sulfates with surfactants
surfactants It is a substance that has a hydrophilic molecule and a hydrophobic molecule
One catches water and the other picks up the oil and dirt in your hair. The result is that they mix with each other, and your hair gets clean in a few seconds.
There are surfactants that contain sulfates and there are sulfates freeThe sulfates free cleanse your hair without removing a large part of the natural oils in it or causing erosion of its particles or dryness.
You can use sulfate-containing shampoo once every month or two if you want to do a deep cleaning of your hair and scalp, but it is not suitable for permanent use.
Our shampoo is suitable for use up to 3 times a week without damage as it does not contain sulfates 
Is there a shampoo without sulfates or trade tricks?
