Lets say your scalp has a hairline scar and that part was hairless. After excising that portion and applying powder, it regrew hair back.

Does it mean that the scar is gotten rid of? And also, would these be an amazing breakthrough for people out there?

What kind of powder?

We have not really learned how to cut human skin without leaving a scar. Unless they’re doing really remarkable things with lasers nowdays that I’m not aware of, any excision would leave a scar. So, these would not be an amazing breakthrough. But what kind of is an amazing breakthrough is that they figured out a while back not to make scars on the head that go straight across, but rather in a zigzag fashion, so that hair can grow back in a somewhat normal way.

You need to try to rephrase what you want to know. What you typed is not clear in meaning.

through research i found this:

[http://www.nyhairloss.com/acell.htm](http://www.nyhairloss.com/acell.htm)

it seems like the scalp which was hairless because of the scar inhibiting the growth of the hair managed to regenerate hair after that portion of the scalp was excised and placed with ecm.

what does anyone think about this? I have other stuff to show you if you’re interested.
