I've never liked my hairline and therefor never wear my hair slicked back outside my home. I'm now starting up a project to try to change it. I massage the temples (that's where I want the hairline to fill in) once or twice every day with Moonchaser's Sweet Success Hair Oil ( http://forums.longhaircommunity.com/showthread.php?t=38114 ). I've started doing this on May 22 and I believe the babyhair has gotten a little longer and maybe even a few more. Could be just wishful thinking though....
