Everyone responds a little bit different post-op. Most guys see the need to begin trimming the exisitng hair between one month and roughly three months post-op depending on how short of a hair style they wish to have.

On average, exisitng hair grows at roughly 1/2 inch per month. But sometimes this can be slower as the scalp recovers from the overall trauma from the surgery.

Eventually as the new transplants gain length and you trim the exisitng hair, they will both blend in togethor and then you can begin cutting the entire hair mass togethor.
