Do you need to spray the new grafts after hair implant?

Our clinic has gone back and forth over the need to spray grafts after surgery. We always supply patients with saline to spray and also recommend progressive washes after surgery. I find that those who keep the scalp moist and clean heal well and that their scabs fall off easier. I don't like large crusts forming. Though I don't stress spraying every 30 min like I used to, I still recommend spraying the scalp. I'm not aware of any good studies done to compare the two aftercare methods though this would be an interesting experiment. 

I recommend to all my patients that they should be spraying normal saline spray (salt spray) for the first 4-5 days post surgery. 

I always wash off the crusts in the first day so that they never form, I recommend that it is done every day so that the recipient area always remains clean. Crusting on the recipient area is a reflection of poor post operative care
