I know this is years down the line, but when Juvista comes out, do you think that Juvista combined with tricho closure on HT scars (either after the process or in a revision) will allow men to cut their hair down to a 1 grade or even to the skin without the scar being too obvious? I know your response would be conjecture at this point, but it would be interesting to get your thoughts.
The scarring may be reduced, giving it a better ability to blend in (without being hyper- or hypo-pigmented or raised), but the hair will not grow on the scar. Scarring is very individualized. Even under the worst case scenario without a trichophytic closure, some people heal great and are able to cut their hair really short without visible scarring in the donor area. How well you scar is also a genetic factor (much like hair loss) and there is only so much you can do.
If Juvista does as it sets out to (eliminate scarring with a simple injection at incision site), it could be great for a percentage of those that it works for, but the drug just failed in its most recent clinical trial. Read Renovo, Shire Developing Anti-Scar Drug and Bad news on drug rocks Renovo for more.
So, the short answer to your question is… probably not.
