I doubt common sense all the time.
For example,when you wash your hair,how do you do it?
I just use water.
Don’t see me as a dirty man.
Let me explain.
Generally shampoo has lots of chemical materials.
They really damage your scalp.
It’s like you are pulling your hair all the time.
Water is enough to wash your hair.
Let’s trust indigenous bacteria.
Have an amazing day!!!
