@Walter Hinteler,
Not to you, Walter, just whom I am answering -
I need to inform you that our hair is different, around the world, and within countries, and within families. I remember giving bad advice to some guy from India when I didn't know then what I was talking about, perhaps twelve years ago. I stopped that shortly, but hope that guy lived through my bad advice.
Anyway, hair growth varies.
Live with it. Enjoy your hair, however it is.
