Wanting to grow out mustache to cover scar on upper lip. Will hair grow where there's scar tissue?

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.

The answer to your question depends on whether there are healthy hair follicles in the scar.

If there are then hair will grow from the follicles.  If not hair will not grow.

The simplist approach is to not shave the area for a few  days and see if there is a bald spot in the scar or whether hair grows from the scar.

In general, hairs do not grow in/through scars in any significant quantity. As a consequence, you may still be able to clearly see the scar as a hairless area even with a moustache but this would depend on several factors. The only way to determine if it can help camouflage the scar is to grow one and see if it is an improvement (or if you look better with a moustache in general!).

If the scar is fairly wide, a scar revision may be able to reduce it enough so that it won't be as visible or can be better hidden with a moustache.
