How can scalp hair follicles be maintained to be healthy?

The simple way is to use products that can care for scalp hair follicles. You can use hot springs. Anyway, I've been using it for more than three months now, not to mention that my hair is much longer, but now my hair oil is obviously much less, and I basically lose very little every time I wash my hair, like four or five hairs. This is really incomparable with my previous state.
