Hair used to grow vertically, but recently it always grows close to the scalp. What is the reason?

Your hair used to grow vertically, which means that you are in good health and there is nothing wrong with it, so your hair grows vertically. Later, it always sticks to your scalp, because your body fat is too high and your hair is oily. The most important thing is that your body is too wet, and your hair is aggravated by oil and moisture, so your head can't grow vertically, so you can only grow vertically against your scalp. If you want your hair to stand on end, you must eat less greasy food and more wet food.
