HASCI and Dr. Gho have never shown a case of a NW7 to NW1. NEVER.
On Bald Truth Talk, there were many attempts to get them to do a 50 graft test but instead they turned it into a 200+ graft test. A subsequent request was made and they denied it. No regrowth was ever noted. Gho likely splits grafts and spreads out individual hairs. Furthermore, and this is peculiar... after the forums investigations into Gho and HASCI, they pulled down their claims of 80% regeneration from their website, leaving it now as a general statement.
The regeneration claim is clearly mostly bullsh*t. The only positive out of a HASCI procedure is that its scarless.
