Hi I had a tranplant before 3 months. I have noticed some growth till now but there are areas with no growth, they are kind of patches. I just wanna know whetehr there is any way like microscope or something which can detect whether patches have hairs beneath. Or I must say that may be the microscope or something just ensure that : " yes there small hairs coming out which are invisible to naked eye".

Thanks in advance for the replies.
