That does not seem to be shock loss as shock loss relates to the native hair that was their prior to surgery. That more looks like grafts that did not survive the procedure and it is strange why they would be in a pattern such as your photo. The grafts also look quite large meaning most likely a larger punch was used for your procedure if this was an FUE or the grafts were cut large if you had a strip procedure done. If large grafts are placed too close to each other there is a chance of decreased survival of the grafts which is what has possibly happened here. The only thing you can do is wait and see how it grows. It is likely you may need a 2nd procedure to correct this but only time will tell
It may be lost grafts or it may NOT be lost grafts. Photos do not make a diagnosis.
It may be lost grafts or it may NOT be lost grafts. Photos do not make a diagnosis. It is also impossible to tell without knowing what was done. For photo comparison you would need a very high resolution photo of what where there BEFORE and AFTER. If you are concerned about lost grafts, it is best to follow up with your doctor for a recheck.
some people may experience general thinning after procedure. However for the loss to be localized just in one area is unusual at this point all you can do is wait and see if it grows back.
Shock loss means the loss of native hair, not the grafts, so by definition you have not experienced shock loss just loss of a few grafts by what you are describing.
Loss of grafts or shock loss?
Judging by the picture alone it is difficult to tell if you lost grafts. It is not uncommon, however, to see a few hairs shedding as the scabs shed. It looks like you are healing well. I would go back to the doctor who performed your surgery and ask him or her if these empty areas were actually transplanted or not. A simple exam with a videomicroscope should answer this question.
