Sounds like this is a star in L.A. (as opposed to N.Y.) who's hyping
an alleged miracle product privately rather than as celebrity endorser
on an infomercial that I've missed because I don't have the TV on in
the wee hours.
Google cached this exchange from a hair-loss chat board on 2/8/1999:
j**2: Luke Perry is thinning and receeding, but I expected him to be
worse off than he is now....
B*****n: Luke had to have had something done.
Is Luke Perry's hair the shade of a chestnut?
It's gotta be Matthew McConaughey. A while back, he was photographed in
airports, restaurants, etc., forever massaging Rogaine into his scalp.
And more recently, he went on Letterman and did an interview with
People, attributing his miraculous hair regrowth to some potion called
Regenix (apparently, the company even has the Letterman clip running on
their website).
