I've started to notice some new hair growth around the 3 month mark. It's not a whole lot yet but some very fine thin hairs. When I look in the mirror it's difficult to see to be quite honest because the hairs are so short and thin. The way I really noticed them was taking pictures without flash close to my scalp at an angle and not top down. Take a pic in a room with natural daylight coming in without having any direct sunlight hitting your head. It's still very early so anything you do see will be quite thin and only around 10% of your growth. I think by the end of this month you should see growth if nothing yet.
Hang in there, I know it's tough not too continuously examine your hair but you have made it past the waiting stage.
Plus Dr. Bloxham has some great results. You'll be surprised once it starts growing you will see how quickly things fill in.
