Patchy growth at 11 months?

Dear tomforde,Thank you for your question.  Following a hair restoration procedure, typically by 11 months, the overwhelming majority of hairs that are going to grow have either grown out or at least started to grow.  This is determined by the physiology of the hair follicle.  Unlike nail beds, which make our fingernails for the duration of our lives, hair follicles make hair in cycles.  The timing of the cycles is as follows:Anagen (growing phase): 2-7 yearsCatagen (short phase before resting phase): 2-3 weeksTelogen (resting phase): 3-8 monthsThe stress of the FUE hair transplant can trigger a portion of the follicles to come out of the anagen phase of growth and enter catagen, followed by 3-8 months of telogen.  The hairs re-enter the anagen, or growing phase, after 3-8 months.  So, the follicles that shed their hairs as a result of the transplant typically return by 8 months.  By 11 months I would consider you nearly at the end of the "new hair" growth.  Uncommonly it can take 18-24 months to see the full effect of the hair restoration. I would suggest a return appointment with your treating physician to discuss the results.

First and foremost follow up with your doctor.You may have un-diagnosed hair loss such as alopecia areata (patchy hair loss).You may have an infection causing hair loss (such as ring worms)You may have poor surgical results.The best bet is to follow up with your doctor. 

Generally at 11 months you should not really have patchy results.  Most likely those grafts did not survive.  I would recommend following up with your doctor and discuss about possibly having it corrected.
