Cleft Lip, What Shall of Do?

I have a scar on the upper side of the lip and I need to get a hair implant/transplant. I’m nearly 18 years old and I have a beard/mustache and the scar doesn’t help at all. Any help or advice will be appreciated

A hair transplant into the scar will completely hide the scar. This is an excellent solution. If the scar is small and you don’t have to grow a mustache or can’t because you don’t have enough mustache hair, then a highly specialized cosmetic tattoo called SMP can hide it.  You can actually do have both SMP and a mustache transplant for the absolute best result, see https://scalpmicropigmentation.com/
