I didn't moisten my scalp for the first 3 days after the Hair Transplant procedure, did I dry my grafts out?

The short answer is no- you probably did not affect the grafts at all, but you may have increased your recovery time.After hair transplant, surgeons will recommend gently washing the area with water or saline to keep the area moist and prevent crusting. The grafts themselves, however, are receiving nutrients from the surrounding skin. While not following these instructions can lead to a build up of crusting and delayed healing, it is unlikely it would have a major affect on the viability of the grafts. You are 4 months out and often at least some of the grafts are in a temporary shock phase. Be patient, stay in close contact with your surgeon and give things time.

It is best to follow your doctor's advice over advice from the Internet. Don't follow advice from YouTube videos.  Follow your doctor's advice.

Thanks for your query. You did absolutely what was required to be done post hair transplant. Continuously using wet towel is not very required. Just keep applying Minoxidil and your hair transplant will be perfect. For even the slightest doubt you can still visit your treating doctor. Hope it helps.All The Best
