I feel for the OP as a woman struggling with hair loss. Society treats men with hair loss better than women, but I imagine it is rough all around. If you can accept it, shave it, and go on with your life, more power to you. I have not reached that zen state, so I won't judge anyone who isn't there either.
I'd recommend first going to a dermatologist. Get yourself a diagnosis, because there are different types of hair loss that would lead to different types of treatments. As a woman, I was told that ultimately my loss was triggered by chronic iron deficiency that came from going off the pill (starting to bleed again), followed by multiple pregnancies and nursing. I am also low in vitamin D, and both are needed for maintaining healthy hair. You can have hair loss due to one-off stressful events or just genetics. As a man, it is less likely that you will be iron deficient, but I see the occasional man in my iron deficiency support group, so it does happen. (You need your ferritin to be at least 70 for hair regrowth, something GPs often don't recognize).
A dermatologist can prescribe things that can help. The gold standard is minoxidil. You can buy it OTC as rogaine or the generics, but honestly I found it a pain in the butt to apply daily. Oral minoxidil is cheap and easy to take so I'm on that. It can be paired with something like finasteride for men. I'm also on Spironolactone which is prescribed to women.
