Would highly recommend Platelet Rich Plasma Treatment  in conjunction with Oral Nutritional and Topical Application supplements to boost your hair with abundant active growth factors that shorten the Telogen (falling)Phase and fasten the onset of Anagen  (Active growth) phase. Results with PRP in Telogen Effluvium are seen as soon as few days following the first session itself.

Your hair (after an acute illness) undergoes severe trauma where no nutrition is supplied to it. So , all your hair that is in the growth phase(anagen)gets 'thrown ' into the falling phase (Telogen). So for the hair to grow back (Anagen phase) it will take anywhere between 6 to 8 months. The maths is confusing so I will not confuse you further :) . All I will say is that don't worry . Continue the treatment with your current dermatologist and trust your dermatologist. Things should be fine. And so that you get a clearer picture and an idea on what I am talking about read this please : http://www.skinmatra.com/single-post/2016/11/10/Hair-Woes-10-Things-You-Should-Know-About-Hair
