Is it safe to wear cap after one week after FUE?

sagarkk,It is quite safe to use a cap one week after a hair transplant. It is a very good idea to wear especially if you are going to be exposed to prolonged Sun for 3-4 months after your procedure.Sincerely, Bernardino A. Arocha, MD

Yes, one week is fine for loose hats that don't rub too much on the new grafts. At two weeks you can wear essentially any hat you'd like, assuming all your crusts are off by then.
