Getting bald, bro?
I think as long as its not so cold or hot that it hurts... it wont matter much to your hair. neither will your choice of shampoo... none of that stuff was ever proven.
In factos, lemme tell you a story...
My father once had this big long haired cat. You know the fluffball kind. I think it was like, 40 years ago. So one time this lady sees it who is into breeding cats and says it's a uniquely perfect specimen of its race etc and its fur is so good etc and you should take it to a cat show
There was a cash price involved for the winner and my father took his cat to the cat show. He won the overall price. All these people had a special bathing and combing schedule for their cats... gave them expensive cat food, used expensive shampoos on them....
My father used to go to the park on sundays, shoot some pigeons down from trees and use them to feed his cat, serving them in whole. Once a week He washed the cat in the kitchen sink using ordinary washup liquid.
owned.
That was a mighty boring irrelevant story
Anyway whether or not your hair looks good depends on how clean it is, what you put in it to style it, and how it was cut.... and whether it stays on depends on genetics and hormonal situation
