Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain 
Male Pattern Baldness or  Androgenic Alopaecia is due to sensitivity of hair follicles to Androgenic hormones Ieading to destruction of hair follicles and hairfall..
Application of 2% Mintop lotion that contains 
Minoxidil solution is a low concentration and you should apply atleast 5% Minoxidil solution..
You should consult a Trichologist and get evaluated and a thorough clinical evaluation and investigations like Dermoscopy, Trichogram and blood tests can help in confirming the diagnosis and treatment can be done accordingly..
You can be advised to apply  5%  Minoxidil lotion over the scalp..
You can also be advised to take 
Biotin and 
Multivitamin supplements..
You can be advised to take Finestaride orally..
You can also 
massage your scalp with warm coconut oil..
Avoid brushing your hairs vigorously..
You can also keep the scalp clean and dry..
Hope this information helps..
Thanks and regards.
