Attention: What are we doing WRONG with shampooing of hair?

A lot of women do that but it’s wrong….
Our hair don’t need every day shampooing and hair but most women do this. According to the experts, hair needs shampooing depending on the oil that comes out of the head, and depending on the diameter of them!
There are women with more oily hair, and so they need frequent bathing and there are women with more dry hair that doesn’t require very frequent bathing!
