Question about all these future treatments...

[goldbondmafia]

Do all of them (adderans, replicel, histogen, dr. nigram/stem cell, etc) only grow hair on the top and crown? Say they end up working and being FDA approved, what happens with our hairlines? In every photo ive seen the hairline is gone and not improved in the after photos. It looks like we'll still need some type of hairline restoration followed by fin anyways..

hopefully someone can prove me wrong and show me a future treatment that actually fixes and maintains the hairline!!!!
