How to glue in the hairline

Im new to mask finishing (mask art?) and im working on hairing a blank, I know how to apply the rows, but i can’t use that method for the hairline, any advice?

I know this may not be the best advice, but hot glue worked really well when I readjusted the hair line on my TOTS 78.

i use latex to adhere the hair, with the exception of the very front hairline , where i use tacky glue. If you want to search my youtube site SINGWITHNICK , you’ll see videos on hairing…look for tots tramer conversion. i think i show it on that one.
also do live feeds on my fb page when i’m working

Thank you for the advice!
