A friend had psoriasis and it looked like big flakes coming from his scalp. Maybe you could ask the doctor (or a different doctor) whether this could be the case for you.
what was the kind of treatment ur frnd received?
I think it was a medicated shampoo made for the kind of psoriasis he had. Don't know any other details (I wasn't a close enough friend for him to comment about taking medication).
From your description, it appears like a dandruff issue, in which case anti dandruff shampoo should have helped. May be, you need to consult a general physician (if not already done) and do a full blood test, hormone panel and other health check up to find out if you are suffering from any other health issues and hair fall is just a symptom. Do you have a family history of baldness, especially on mother's side?.
The following link will give you a good discussion on the effectiveness of MESO therapy and other choices, apparently, MESO is not very effective in male pattern baldness treatment.
Hope it helps,
The other thing is, get your thyroid checked. Thyroid problems can cause loss of hair.
