I've been dealing with dandruff and a really itchy scalp for a long time now, and it seems to be getting worse. Over the past two years, I've noticed a significant amount of hair shedding. A few doctors have diagnosed me with seborrheic dermatitis, but nothing seems to be helping.
This could be fungal infection u need to evaluate with your Dermatologist and get appropriate treatment with oral antifungal medications and topical lotions,once the infection is resolved your hair fall would come down,I suggest you not to use minoxidil with active fungal infection,above this your personal hygiene care is more important.
