When you get a hair loss test, do you look at the scalp instead of the hair?

When I thought of hair loss, I only considered the shedding of hair, but the more I looked into it, the more I heard that the scalp environment is also important.

It caught my eye that overall care is necessary rather than simply changing a single product, as factors such as sebum, dryness, and lifestyle habits can have an impact.

In the past, I only cared about the amount of hair loss.
