Thanks for posting your query at DoctorSpring.com
I can understand your concern. I reviewed the pictures. I could see the two photos that you have sent of you at present.
But however from what I see now I would label it as male pattern baldness.
The pattern of thinning is quite characteristic. I would recommend application of rogaine solution on the scalp. This treatment if it works in your case has to be continued life long. I would recommend getting a prescription from your doctor.
Please follow up at regular intervals with your dermatologist.
Please let me know if you have any queries. Take care
