The only way for me to lay my hands on their defaults is through this:
https://spookymuffinsims.tumblr.com...for-a-while-and - please take note it's a MASSIVE file with almost all defaults in it, with no previews. I'm 100% there's the first hair you wanted there but I'm not sure what it replaces. As for the second one, I can't remember if it was there or not, you'd have to look it up. I assume you weren't able to access their defaults as for today? I keep getting the "access denied" and all I can do is request it but I doubt I'll ever get it.
