Admittedly drawing faces is a thing that can be learned very intuitively, as we've seen the faces of many people throughout our lives and it is easy to tell when something is wrong. The first thing I suggest is that you should try to break the face into simpler forms, you can try to simplify the facial features with simple forms (like the nose as a simple box), and you can try to break it down into planes. Avoid drawing flat shapes and do your best to always use 3D forms.
All of this should be done from imagination, this may sound daunting at first but you will learn a lot by trial and error.
And if you want to complement it with an actual method to draw the face/head you can search for the Loomis method on the internet, I personally have never used it, but I've seen plenty of people recommend it
