17 weeks post 4300 FUE. Not sure of the result so far (Photo)

Your results at 17 weeks post hair transplant may not be indicative of the final result. While new growth typically becomes more apparent 3 to four months after a hair transplant, the final result of a hair transplant can take between 12 to 18 months to manifest. Based on these frames of reference, there does not seem to be a cause for alarm about your results so far. You may still want to monitor your growth and keep your doctor appraised of new developments. You may notice shedding in the recipient area within the first few months afterwards, which is a normal part of the growing process—this is due to the hair follicles preparing for new growth.
I have included a link below about the hair transplant process and an estimated timeline of what to expect after the surgery.

It may take six to twelve months to appreciate the results of a hair transplant surgery.  If you are concerned it is best to contact your doctor. 

Most patients experience some results starting as early as 4 months but at times it takes over 6 months to the the result of a hair transplant.  At times you can only see your full results after 8-10 months. 

After three month the new hair will come out of the skin slowly. You should be patient and wait for 10-12 month to see the final result. If you have any questions so please consult with your doctor as he/she knows your case and can give you detailed informations.

There is often not much growth visible to the naked eye at four months.  It takes a good 8-12 months to get final your final results.  I suggest waiting and avoiding YouTube in the interim. 

It takes up to 6 months for the grafts to start growing in some people. I tell everyone to wait at least 6 months before panicing
