I do rock baby hair, it doesn't help that I have a cowlick right in the front of my head. Thats the only place I tend to do it and its not crazy like the 90's. Very soft and girly.....
Ironically, I feel like my hairline behaves best when I just leave it alone and moisturize with olive or coconut oil regularly. My edges look 100x better since I stopped relaxing and obsessing over having my hairline look perfect all the time.
And yeah, I've been slicking my baby hairs too. I never really stopped either, just didn't do it all the time. I've started doing it all the time now. I think it's become popular again partly because of FKA Twigs but I've always liked the look and thought it was cute.
