You seem to be having seborrheic dermatitis
and androgenetic alopecia. Both might have contributed to hair fall
Shaving hair does not improve hair density and hence is not required.
To induce hair growth treatment of both the condition required
Seborrheic dermatitis or dandruff- use antifungal shampoo alternate days
Androgenetic alopecia- minoxidil
solution 1 ml twice in a day( 2 percent approved for females 5 percent for males) along with tablet finesteride 1 mg daily. If this does not help scalp mesotherapy with stem cells can be tried. If the condition has progressed beyond response to medical therapy then hair transplantation
I would suggest that you consult a dermatologist
near by or use ask a specialist feature of this site to get a personalised opinion of your concern.
