People are telling me I have diffuse unpatterned hair loss. Is it true? (Photo)

I have been told on many forum that i might have male pattern baldness or seeing the thinning on my sides and back they are telling me i might have diffues thinning too! I am on currently almost 5 months into finasteride and ketoconazole shampoo! No sides but not good improvement regarding hair too! I was just wondering that could i use 2 mg oral minoxidil. I used topical and it was great but had to stop it as it caused psoriasis! So my question is can i use oral minoxidil and what dose?
