3 months post fue I had 2700 grafts to the temple area but only a few have grown in and mostly on the left? (Photos)

It can take 6 to 12 months after surgery to see results.  If you are concerned it is best to contact your doctor

At 3 months no appreciable results can be noted.  The follicles are in a resting phase that will last for several months.  On average, the follicles will start to regrow between 4 to 6 months after the procedure.  

At 3 months I wouldn't worry too much about patchy or uneven growth. This is the very beginning of your hairs sprouting. If there's still some significant differences in different areas on your scalp past 6 months, you should talk to your doctor about your concerns.
