I'm 40yrs old 2 months post brow/forehead lift (endo w/ entodines) and am healing well. Hair is growing back over the incisions, but not so well on a couple of the incisions/scars. Is it better to use scar gel or hair growth serum on these two scars? I've been using a mix of rogaine with latisse ($$ but I get wholesale) and am very happy with results. But am wondering if I'm better to use scar gel to soften the 2 scars which may allow hair to grow through? Please let me know - much appreciated!
